Power Integrations
2015 Annual Report
igbt drivers
Dear Fellow Stockholders,
While our revenues and earnings fell in 2015 against a challenging economic backdrop, cash flows increased nicely from the
prior year, and we returned a substantial amount of cash to investors while also making important investments to support our
future growth. We also demonstrated the tremendous potential of our new InnoSwitch™ products, which have garnered a
significant share of the “rapid” charger market for smartphones and are now making inroads in other applications. We
believe not only that InnoSwitch will be our next flagship product family for the AC-DC power-supply market, but that the
technological breakthroughs embodied in InnoSwitch chips will be the foundation of a mega product cycle, spawning
products for a wider range of power-conversion applications and driving a significant expansion of our addressable market
in the years ahead. I’ll expand on that idea further after a brief recap of our 2015 results.
Full-year revenues fell by one percent in a tough economic climate and in the face of challenging conditions in certain end-
markets. Most notably, we saw a 30-percent reduction in sales into the computing market, where power-supply vendors
slashed purchases to reduce inventories in the face of falling PC demand. High-power revenues – from sales of our SCALE™
IGBT-driver products – were also lower, reflecting softness in energy markets and the effects of currency fluctuations on our
European sales. Finally, we saw lower sales into the LED-lighting market, reflecting our decision to deemphasize low-end
bulb designs in favor of brand-name bulbs as well as commercial and industrial lighting applications, where the benefits of
integration (i.e., reliability, size and efficiency) are valued more highly. This repositioning has improved the stability and
profitability of our lighting business and, with the transition now largely complete, we are poised to grow our lighting
revenues once again on the strength of several promising new products in our LYTSwitch™ line of LED-driver chips.
In light of these revenue headwinds, we managed our spending carefully, and held operating expenses essentially flat in
2015 compared to the prior year. Our earnings nevertheless declined at a rate greater than that of our revenues, due mainly to
a lower gross-profit margin. While a lower gross margin is nothing to boast about, the good news is that in this case it
largely reflects the early success of our InnoSwitch products. Throughout our history, new products have at times created
short-term pressure on our margins when their revenue contributions have ramped before we’ve had time to optimize unit
costs. In the case of InnoSwitch, this issue is compounded by the fact that our first target market has been smartphone
chargers, which inherently bring a below-average gross margin due mainly to high volumes and a relatively concentrated
customer base.
Fortunately, we believe these margin issues are largely transitory, and we expect our gross margin to stabilize in 2016.
InnoSwitch ICs are now being designed into higher-margin industrial and consumer-appliance applications, and we expect
these designs to begin contributing revenues later this year. Also this year we plan to introduce our next-generation of
InnoSwitch products, which we believe will not only expand the addressable market for InnoSwitch by addressing higher-
power applications, but also improve the product family’s cost-effectiveness by utilizing a new, higher-density process
technology.
Despite the reduction in earnings, cash flow from operations grew by eight percent from the prior year to $92 million, and
we put our cash to good use during the year. In January 2015 we bolstered our design talent with the acquisition of UK-
based Cambridge Semiconductor for $23 million, and in September we invested $10 million to acquire a third building in
our Silicon Valley headquarters complex, ensuring that we will have adequate space to grow for years to come. We also
returned a considerable amount of cash to stockholders during the year, repurchasing more than 1.2 million shares for $54
million. This resulted in a four-percent reduction in weighted-average diluted share count for the full year; in fact, our share
count has declined by more than ten percent since mid-2008 as we have taken advantage of market volatility to repurchase
shares at opportune moments. We paid out $14 million in dividends during the year, and announced in February 2016 that
we have increased our quarterly dividend to $0.13 per share for 2016 (from $0.12 per share throughout 2015). Even after
these cash outflows, our balance sheet remains as healthy as ever, with no debt and $174 million in cash and investments
exiting the year (a decrease of just $1 million from the prior year).
While not satisfied with our 2015 results, we believe we exited the year on an improving trajectory. Fourth-quarter revenues
increased modestly on a year-over-year basis, which compares favorably to a four-percent decrease for the analog
semiconductor market.1 Likewise, the outlook we issued in February for the first quarter of 2016 called for two-percent year-
over-year growth at the midpoint of the range, in contrast to the declines projected by many of our industry peers.

Perhaps a more noteworthy indicator of our improving outlook is our performance last year in the communications end-
market. Fueled largely by the success of InnoSwitch products in rapid-charging applications for smartphones, revenues from
the communications market grew more than 20 percent in 2015. We see this as an important harbinger for two reasons.
First, we believe the growth in communications is more than a one-year story. Rapid-charging emerged as a disruptive force
in the mobility market last year, creating a need for high-value integrated solutions in a market where commodity discrete
designs had become predominant. InnoSwitch products fulfill the needs of this market beautifully, and we are winning a
sizeable share, with designs now in production at many top-tier smartphone OEMs. We believe rapid-charging will be a
growth driver for years to come as power levels continue to rise, charging speed becomes an important differentiator in
mobile devices, and new technologies such as USB-PD and type-C connectors come to market.
Second, as successful as we’ve been in chargers with InnoSwitch, we believe the technology may prove even more attractive
in embedded power supplies, where efficiency specifications tend to be more challenging and where reliability is often the
most important consideration due to the high repair and replacement cost of many end products. We now have InnoSwitch
designs in progress across dozens of applications, including appliances, consumer electronics and industrial applications.
Looking further ahead, we also have in our pipeline products that will bring InnoSwitch technology to other end markets
such as lighting and even high-power IGBT-driver applications such as renewable energy systems and industrial motor
drives. Whereas our current portfolio of IGBT-driver products is aimed primarily at very high-power applications, these new
products will extend our reach to lower power levels, roughly doubling our served available market (SAM) for IGBT drivers
and expanding our total SAM to more than $3 billion. We also continue to invest in longer-term R&D projects with the
potential to expand our SAM even further, while maintaining focus on our core competency of high-voltage power
conversion.
Finally, I’d like to highlight yet another favorable result in our patent litigation against Fairchild Semiconductor. In 2014 a
jury in California found that Fairchild infringed two of our patents, and awarded us $105 million in damages. Fairchild
contested the award based on changes in case law that occurred after the initial verdict, and was granted a new trial to
determine a revised damage award. As we announced in December, the award resulting from the new trial was $140 million,
one-third larger than the original amount. While the outcome of the case is subject to further challenges, we are hopeful that
this verdict marks a turning point, and that Fairchild’s infringement will finally cease.
In summary, while our 2015 financial results were impacted by a variety of factors, a closer look reveals improving trends
relative to our industry peer group, and early indications that our investments in innovation are paying off in the form of a
promising new product cycle. The high-voltage power-conversion market continues to demand ever-greater levels of
innovation, integration and energy efficiency, and no company is better equipped to meet these demands. We are as
confident as ever in the future of our business, and I look forward to reporting on our progress in the year ahead.
Sincerely,
Balu Balakrishnan
President and Chief Executive Officer

PART I.
Item 1. Business.
Overview
We design, develop and market analog and mixed-signal integrated circuits (ICs) and other electronic
components and circuitry used in high-voltage power conversion. Our products are used in power converters that
convert electricity from a high-voltage source (typically 48 volts or higher) to the type of power required for a
specified downstream use. In most cases, this conversion entails, among other functions, converting alternating
current (AC) to direct current (DC) or vice versa, reducing or increasing the voltage, and regulating the output
voltage and/or current according to the customer’s specifications.
A large percentage of our products are ICs used in AC-DC power supplies, which convert the high-voltage
AC from a wall outlet to the low-voltage DC required by most electronic devices. Power supplies incorporating
our products are used with all manner of electronic products including mobile phones, computers, entertainment
and networking equipment, appliances, electronic utility meters, industrial controls and LED lights.
Since our May 2012 acquisition of CT-Concept Technologie AG (Concept), we also offer insulated-gate
bipolar transistor (IGBT) drivers - circuit boards containing multiple ICs, electrical isolation components and other
circuitry - used to operate arrays of high-voltage, high-power transistors known as IGBT modules. These driver/
module combinations are used for power conversion in high-power applications (i.e., power levels ranging from
tens of kilowatts up to one gigawatt) such as industrial motors, solar- and wind-power systems, electric vehicles
and high-voltage DC transmission systems.
Our products bring a number of important benefits to the power-conversion market compared with less
advanced alternatives, including reduced component count and design complexity, smaller size, higher reliability
and reduced time-to-market. Our products also improve the energy efficiency of power converters, helping our
customers meet the increasingly stringent efficiency standards that have been adopted around the world for many
electronic products, and improving the efficacy of renewable-energy systems, electric vehicles and other high-
power applications.
While the size of our addressable market fluctuates with changes in macroeconomic conditions, the
market has generally exhibited only a modest growth rate over time as growth in the unit volumes of power
converters has largely been offset by reductions in the average selling price of components in this market. Therefore,
the growth of our business depends primarily on our penetration of the addressable market, and our success in
expanding the addressable market by introducing new products that address a wider range of applications. Our
growth strategy includes the following elements:
•
•
Increase the penetration of our ICs in the “low-power” market. The largest proportion of our
revenues comes from power-supply applications requiring 500 watts of output or less. We continue
to introduce more advanced products that make our IC-based solutions more attractive in this
market. We have also increased the size of our sales and field-engineering staff considerably in
recent years, and we continue to expand our offerings of technical documentation and design-
support tools and services to help customers use our ICs. These tools and services include our PI
Expert™ design software, which we offer free of charge, and our transformer-sample service.
Increase the penetration of our products and the size of our market opportunity in “high-power”
applications. By virtue of our acquisition of Concept in 2012, we are now able to bring the benefits
of integration to higher-power applications (up to one gigawatt). In particular, we sell our IGBT-
driver products into applications such as industrial motor drives, renewable energy systems, DC
4
transmission systems and electric vehicles. We seek to further expand the size of our market
opportunity in the future by introducing new IGBT-driver products that will enable us to serve a
wider range of power levels in the “high-power” market.
•
Capitalize on the growing demand for more energy-efficient electronic products and lighting
technologies, and for cleaner energy and transportation technologies. We believe that energy-
efficiency is becoming an increasingly important design criterion for power supplies due largely
to the emergence of standards and specifications that encourage, and in some cases mandate, the
design of more energy-efficient electronic products. For example, in 2008 the U.S. Department of
Energy implemented mandatory federal standards governing the efficiency of external power
supplies; these standards have been tightened as of early 2016. Power supplies incorporating our
ICs are generally able to comply with all known efficiency specifications currently in effect,
including the new U.S. federal standards mentioned above.
Additionally, technological advances combined with regulatory and legislative actions are resulting
in the adoption of alternative lighting technologies such as LEDs. We believe this presents a
significant opportunity for us because our ICs are used in driver (i.e., power-supply) circuitry for
high-voltage LED lighting applications. Finally, the growing desire for less carbon-intensive sources
of energy and modes of transportation represents an opportunity for us since our IGBT drivers are
used in renewable-energy systems as well as electric trains and electric vehicles.
Industry Background
Virtually every electronic device that plugs into a wall socket requires a power supply to convert the high-
voltage alternating current provided by electric utilities into the low-voltage direct current required by most
electronic devices. A power supply may be located inside a device, such as a consumer appliance or desktop
computer, or it may be outside the device as in the case of a mobile-phone charger or an adapter for a cordless
phone.
Until approximately 1970, AC-DC power supplies were generally in the form of line-frequency, or linear,
transformers. These devices, consisting primarily of copper wire wound around an iron core, tend to be bulky and
heavy, and typically waste a substantial amount of electricity. In the 1970s, the invention of high-voltage discrete
semiconductors enabled the development of a new generation of power supplies known as switched-mode power
supplies, or switchers. These switchers generally came to be a cost-effective alternative to linear transformers in
applications requiring more than about three watts of power; in recent years the use of linear transformers has
declined even further as a result of energy-efficiency standards and higher raw-material prices.
Switchers are generally smaller, lighter-weight and more energy-efficient than linear transformers.
However, switchers designed with discrete components are highly complex, containing numerous components and
requiring a high level of analog design expertise. Further, the complexity and high component count of discrete
switchers make them relatively costly, difficult to manufacture and prone to failures. Also, some discrete switchers
lack inherent safety and energy-efficiency features; adding these features may further increase the component
count, cost and complexity of the power supply.
In high-power systems such as industrial motor drives, electric locomotives and renewable-energy
systems, power conversion is typically performed using arrays of high-power silicon transistors known as IGBT
modules; these modules are operated by electronic circuitry known as IGBT drivers, whose function is to ensure
accurate, safe and reliable operation of the IGBT modules. Much like discrete power supplies, discrete IGBT
drivers tend to be highly complex, requiring a large number of components and a great deal of design expertise.
5
Our Highly Integrated Approach
In 1994 we introduced TOPSwitch, the industry’s first cost-effective high-voltage IC for switched-mode
AC-DC power supplies; we have since introduced a range of other product families such as TinySwitch, LinkSwitch,
Hiper and InnoSwitch which have expanded the range of power-supply applications we can address. In May 2012
we acquired Concept, further expanding our addressable market to include IGBT drivers.
Our ICs and IGBT drivers drastically reduce the complexity and component count of power converters
compared to typical discrete designs by integrating many of the functions otherwise performed by numerous discrete
electronic components, and by eliminating (or reducing the size and cost of) additional components through
innovative system design. As a result, our products enable power converters to have superior features and
functionality at a total cost equal to or lower than that of many competing alternatives. Our products offer the
following key benefits:
•
Fewer Components, Reduced Size and Higher Reliability
Our highly integrated ICs and IGBT drivers enable designs with up to 70% fewer components than
comparable discrete designs. This reduction in component count enhances reliability and efficiency, reduces size,
accelerates time-to-market and results in lower manufacturing costs for our customers. Power supplies that
incorporate our ICs are also lighter and more portable than comparable power supplies built with copper-and-iron
linear transformers, which are still used in some low-power applications.
•
Reduced Time-to-Market, Enhanced Manufacturability
Because our products eliminate much of the complexity associated with the design of power converters,
designs can typically be completed in much less time, resulting in more efficient use of our customers' design
resources and shorter time-to-market for new designs. The lower component count and reduced complexity enabled
by our products also makes designs more suitable for high-volume manufacturing. We also provide extensive
hands-on design support as well as online design tools, such as our PI Expert design software, that further reduce
time-to-market and product development risks.
•
Energy Efficiency
Our patented EcoSmart technology, introduced in 1998, improves the energy efficiency of electronic
devices during normal operation as well as standby and “no-load” conditions. This technology enables
manufacturers to cost-effectively meet the growing demand for energy-efficient products, and to comply with
increasingly stringent energy-efficiency requirements. Our Concept IGBT drivers also enable very high efficiency
in high-power systems; in many such systems, such as renewable-energy installations, even small efficiency gains
can dramatically shorten the payback period over which the cost of a system is recovered through energy savings.
•
Wide Power Range and Scalability
Products in our current IC families can address AC-DC power supplies with output power up to
approximately 500 watts as well as some high-voltage DC-DC applications; our Concept IGBT drivers are used
in applications with power levels as high as one gigawatt. Within each of our product families, the designer can
scale up or down in power to address a wide range of designs with minimal design effort.
Energy Efficiency
Power supplies often draw significantly more electricity than the amount needed by the devices they
power. As a result, billions of dollars' worth of electricity is wasted each year, and millions of tons of greenhouse
gases are unnecessarily produced by power plants. Energy waste occurs during the normal operation of a device
6
and in standby mode, when the device is plugged in but idle. For example, computers and printers waste energy
while in “sleep” mode. TVs that are turned off by remote control consume energy while awaiting a remote-control
signal to turn them back on. A mobile-phone charger left plugged into a wall outlet continues to draw electricity
even when not connected to the phone (a condition known as “no-load”). Many common household appliances,
such as microwave ovens, dishwashers and washing machines, also consume power when not in use. In fact, a
2015 study by the National Resources Defense Council found that devises that are "always-on" but inactive may
be causing as much as $19 billion in annual energy waste in the U.S alone.
Lighting is another major source of energy waste. Less than 5% of the energy consumed by traditional
incandescent light bulbs is converted to light, while the remainder is wasted as heat. The Alliance to Save Energy
has estimated that a conversion to efficient lighting technologies such as compact fluorescent bulbs and light-
emitting diodes, or LEDs, could save as much as $18 billion worth of electricity and 158 million tons of carbon
dioxide emissions per year in the United States alone.
In response to concerns about the environmental impact of carbon emissions, policymakers are taking
action to promote energy efficiency. For example, the ENERGY STAR® program and the European Union Code
of Conduct encourage manufacturers of electronic devices to comply with voluntary energy-efficiency
specifications. In 2007 the California Energy Commission (CEC) implemented mandatory efficiency standards
for external power supplies. The CEC standards were implemented nationwide in the United States in July 2008
as a result of the Energy Independence and Security Act of 2007, or EISA; these federal standards have been
tightened in early 2016. Similar standards for external power supplies took effect in the European Union in 2010
as part of the EU’s EcoDesign Directive for Energy-Related Products.
In 2009 the CEC announced mandatory efficiency standards for televisions, which took effect in 2011,
and in January 2012 the CEC announced mandatory efficiency standards for battery-charging systems, which took
effect in 2013.
In 2010, the EU EcoDesign Directive implemented standards limiting standby power consumption on a
wide range of electronic products; the limit was reduced by 50 percent beginning in 2013, with many products
now limited to 500 milliwatts of standby usage. The EISA law also required substantial improvements in the
efficiency of lighting technologies beginning in 2012; as of 2014, traditional 100-, 75-, 60- and 40-watt bulbs may
no longer be manufactured or sold in the United States. Plans to eliminate conventional incandescent bulbs have
also been announced or enacted in other geographies such as Canada, Australia and Europe.
We believe we offer products that enable manufacturers to meet or exceed these regulations, and all other
such regulations of which we are aware. Our EcoSmart technology, introduced in 1998, dramatically reduces waste
in both operating and standby modes; we estimate that this technology has saved billions of dollars’ worth of
standby power worldwide since 1998. In 2010 we introduced our CapZero and SenZero IC families, which eliminate
additional sources of standby waste in some power supplies; we have also introduced a range of product families
designed specifically for LED-lighting applications.
Products
Below is a brief description of our products:
•
AC-DC power conversion products
TOPSwitch, our first commercially successful product family, was introduced in 1994. Since that time
we have introduced a wide range of products (such as our TinySwitch, LinkSwitch and Hiper families) to increase
the level of integration and improve upon the functionality of the original TOPSwitch, and to broaden the range
of power levels we can address. In 2010 we introduced our CapZero and SenZero families, which reduce standby-
power consumption in certain applications by eliminating waste caused by so-called bleed resistors and sense
7
resistors. Also, by virtue of our 2010 acquisition of Qspeed Semiconductor, we offer a range of high-performance,
high-voltage diodes known as Qspeed diodes.
In 2014 we introduced our InnoSwitch product family, which are the first-ever power-supply ICs to
combine primary, secondary and feedback circuits into a single package, utilizing a proprietary technology known
as FluxLink to enable precise control without the need for optical components, which tend to add cost and diminish
the reliability of power supplies.
In January 2015 we further expanded our product portfolio with the acquisition of Cambridge
Semiconductor Ltd., a producer of controller ICs for low-power AC-DC applications. Since 2010 we have also
introduced products designed specifically for LED-lighting applications, including our LYTSwitch family.
This portfolio of power-conversion products generally addresses power supplies ranging from less than
one watt of output up to approximately 500 watts of output, a market we refer to as the “low-power” market. This
market consists of an extremely broad range of applications including mobile-device chargers, consumer appliances,
utility meters, LCD monitors, main and standby power supplies for desktop computers and TVs, LED lamps, and
numerous other consumer and industrial applications.
•
IGBT drivers
As a result of our May 2012 acquisition of Concept, we offer a range of IGBT-driver products sold
primarily under the SCALE and SCALE-2 product-family names. These products are fully assembled circuit boards
incorporating multiple ICs, electrical isolation components and other circuitry. We offer both ready-to-operate
“plug-and-play” drivers designed specifically for use with particular IGBT modules, as well as “driver cores,”
which provide more basic driver functionality that customers can customize to their own specifications after
purchase. In addition, we offer custom drivers based on our SCALE technology.
•
High-voltage DC-DC products
The DPA-Switch family of products, introduced in June 2002, was the first monolithic high-voltage DC-
DC power conversion IC designed specifically for use in distributed power architectures. Applications include
power-over-Ethernet powered devices such as voice-over-IP phones and security cameras, as well as network hubs,
line cards, servers, digital PBX phones, DC-DC converter modules and industrial controls.

Sales, Distribution and Marketing
We sell our products to original equipment manufacturers, or OEMs, and merchant power-supply
manufacturers through our direct sales staff and a worldwide network of independent sales representatives and
distributors. We have sales offices in the United States, Switzerland, United Kingdom, Germany, Italy, India, China,
Japan, South Korea, the Philippines, Singapore and Taiwan. Direct sales to OEMs and merchant power supply
manufacturers represented approximately 25% of our net product revenues for each of 2015, 2014 and 2013, while
sales to and through distributors accounted for approximately 75% for each of 2015, 2014 and 2013. Most of our
distributors are entitled to return privileges based on sales revenue and are protected from price reductions affecting
their inventories. Our distributors are not subject to minimum purchase requirements, and sales representatives
and distributors can discontinue marketing our products at any time.
Our top ten customers, including distributors that resell to OEMs and merchant power supply
manufacturers, accounted for 60% of our net revenues for 2015 and 59% in each of 2014 and 2013.

In 2015, 2014 and 2013 sales to customers in the United States accounted for approximately 5% of our
net revenues in each of the respective years, and sales to customers outside of the United States accounted for
approximately 95% of our net revenues in the same periods. See Note 6, “Significant Customers and International
Sales,” in our Notes to Consolidated Financial Statements regarding sales to customers located in foreign countries.
See our consolidated financial statements regarding total revenues and profit for the last three fiscal years.
We are subject to risks stemming from the fact that most of our manufacturing and most of our customers
are located in foreign jurisdictions. Risks related to our foreign operations are set forth in Item 1A of this Annual
Report on Form 10-K, and include: potential weaker intellectual property rights under foreign laws, the burden of
complying with foreign laws and foreign-currency exchange risk. See, in particular, the risk factor “Our international
sales activities account for a substantial portion of our net revenues, which subjects us to substantial risks” in Item
1A of this Form 10-K.
Backlog
Our sales are primarily made pursuant to standard purchase orders. The quantity of products purchased
by our customers as well as shipment schedules are subject to revisions that reflect changes in both the customers'
requirements and in manufacturing availability. Historically, our business has been characterized by short-lead-
time orders and quick delivery schedules; for this reason, and because orders in backlog are subject to cancellation
or postponement, backlog is not necessarily a reliable indicator of future revenues. Furthermore, except in the case
of our IGBT-driver products, we do not recognize revenue on distribution sales until our distributors report that
they have sold our products to their customers. As a result, our revenues in a given period can differ significantly
from the value of the products we ship in the same period. We believe this further reduces the reliability of order
backlog as an indicator of future revenues.
Research and Development
Our research and development efforts are focused on improving our technologies, introducing new
products to expand our addressable markets, reducing the costs of existing products, and improving the cost-
effectiveness and functionality of our customers' power converters. We have assembled teams of highly skilled
engineers to meet our research and development goals. These engineers have expertise in high-voltage device
structure and process technology, analog IC design, system architecture and packaging.
In 2015, 2014 and 2013, we incurred costs of $57.5 million, $55.0 million and $51.7 million, respectively,
for research and development (R&D). R&D expenses increased in 2015 compared to 2014, driven primarily by
the addition of employees in connection with our acquisition of Cambridge Semiconductor Limited (CamSemi)
(refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements, for details); the increase in
headcount caused a corresponding increase in salary and other employee-related expenses. R&D expenses increased
in 2014 compared to 2013, driven primarily by increased payroll and related expenses as a result of increased
headcount, due mainly to the expansion of our product-development efforts.
Intellectual Property and Other Proprietary Rights
We use a combination of patents, trademarks, copyrights, trade secrets and confidentiality procedures to
protect our intellectual-property rights. As of December 31, 2015, we held 814 U.S. patents and had received
foreign patent protection on these patents resulting in 462 foreign patents. The U.S. patents have expiration dates
ranging from 2016 to 2035. We also hold trademarks in the U.S. and various other geographies including Taiwan,
Korea, Hong Kong, China, Europe and Japan.
We regard as proprietary some equipment, processes, information and knowledge that we have developed
and used in the design and manufacture of our products. Our trade secrets include a high-volume production process
that produces our patented high-voltage ICs. We attempt to protect our trade secrets and other proprietary-
10
information through non-disclosure agreements, proprietary information agreements with employees and
consultants, and other security measures.
Long-lived Assets
Our long-lived assets consist of property and equipment as well as intangible assets. Our intangible assets
consist of developed and in-process technology, licenses, patents, customer relationships, trade name, domain name
and goodwill. Our long-lived assets, including property and equipment and intangible assets, are located in the
United States and in foreign countries. Approximately 40% of our long lived assets were located in the United
States in 2015, 2014 and 2013, while approximately 60% were held outside of the United States. In 2015, 2014
and 2013 a significant amount of our foreign long-lived assets were located in Switzerland, which held
approximately 18%, 31% and 33%, respectively, of our total long-lived assets. See Note 2, Summary of Significant
Accounting Policies, in our Notes to Consolidated Financial Statements regarding total property and equipment
located in foreign countries.
Manufacturing
We contract with three foundries for the manufacture of the vast majority of our silicon wafers: (1) ROHM
Lapis Semiconductor Co., Ltd., or Lapis, (formerly OKI Electric Industry), (2) Seiko Epson Corporation, or Epson,
(3) X-FAB Semiconductor Foundries AG, or X-FAB. These contractors manufacture wafers using our proprietary
high-voltage process technologies at fabrication facilities located in Japan, Germany and the United States.
Our IC products are assembled and packaged by independent subcontractors in China, Malaysia, Thailand
and the Philippines. Our ICs are tested predominantly at the facilities of our packaging subcontractors in Asia and,
to a small extent, at our headquarters facility in San Jose, California. Our IGBT-driver boards are assembled by
an independent subcontractor in Sri Lanka and tested at our facility in Switzerland.
Our fabless manufacturing model enables us to focus on our engineering and design strengths, minimize
capital expenditures and still have access to high-volume manufacturing capacity. We utilize both proprietary and
standard IC packages for assembly. Some of the materials used in our packages and aspects of assembly are specific
to our products. We require our assembly manufacturers to use high-voltage molding compounds which are more
difficult to process than industry standard molding compounds. We work closely with our contractors on a
continuous basis to maintain and improve our manufacturing processes.
Our proprietary high-voltage processes do not require leading-edge geometries for them to be cost-
effective, and can therefore use our foundries’ older, low-cost facilities for wafer manufacturing. However, because
of our highly sensitive high-voltage process, we must interact closely with our foundries to achieve satisfactory
yields. Our wafer supply agreements with Lapis, Epson and X-FAB expire in April 2018, December 2020 and
December 2020, respectively. Under the terms of the Lapis agreement, Lapis has agreed to reserve a specified
amount of production capacity and to sell wafers to us at fixed prices, which are subject to periodic review jointly
by Lapis and us. In addition, Lapis requires us to supply them with a rolling six-month forecast on a monthly basis.
Our agreement with Lapis provides for the purchase of wafers in U.S. dollars, with mutual sharing of the impact
of the fluctuations in the exchange rate between the Japanese yen and the U.S. dollar. Under the terms of the Epson
agreement, Epson has agreed to reserve a specified amount of production capacity and to sell wafers to us at fixed
prices, which are subject to periodic review jointly by Epson and us. The agreement with Epson also requires us
to supply rolling six-month forecasts on a monthly basis, to provide for the purchase of wafers in U.S. dollars and
to share the impact of the exchange rate fluctuation between the Japanese yen and the U.S. dollar. Under the terms
of the X-FAB agreement, X-FAB has agreed to reserve a specified amount of production capacity and to sell wafers
to us at fixed prices, which are subject to periodic review jointly by X-FAB and us. The agreement with X-FAB
also requires us to supply them with rolling six-month forecasts on a monthly basis. Our purchases of wafers from
X-FAB are denominated in U.S. dollars.
11
Although some aspects of our relationships with Lapis, Epson and X-FAB are contractual, some important
aspects of these relationships are not written in binding contracts and depend on the suppliers' continued cooperation.
We cannot assure that we will continue to work successfully with Lapis, Epson or X-FAB in the future, that they
will continue to provide us with sufficient capacity at their foundries to meet our needs, or that any of them will
not seek an early termination of their wafer supply agreement with us. Our operating results could suffer in the
event of a supply disruption with one or more of our foundries if we were unable to quickly qualify alternative
manufacturing sources for existing or new products or if these sources were unable to produce wafers with acceptable
manufacturing yields.
We typically receive shipments from our foundries approximately four to six weeks after placing orders,
and lead times for new products can be substantially longer. To provide sufficient time for assembly, testing and
finishing, we typically need to receive wafers four weeks before the desired ship date to our customers. As a result
of these factors and the fact that customers’ orders can be placed with little advance notice, we have only a limited
ability to react to fluctuations in demand for our products. We try to carry a substantial amount of wafer and
finished-goods inventory to help offset these risks and to better serve our markets and meet customer demand.
Competition
Competing alternatives to our high-voltage ICs for the power-supply market include monolithic and hybrid
ICs from companies such as Fairchild Semiconductor, STMicroelectronics, Infineon, ON Semiconductor and
Sanken Electric Company, as well as PWM-controller chips paired with discrete high-voltage bipolar transistors
and MOSFETs, which are produced by a large number of vendors, including those listed above as well as such
companies as NXP Semiconductors, Diodes Inc., On-Bright Electronics and Dialog Semiconductor. Self-oscillating
switchers, built with discrete components supplied by numerous vendors, are also commonly used. For some
applications, line-frequency transformers are also a competing alternative to designs utilizing our products. Our
IGBT-driver products compete with alternatives from such companies as Avago, Infineon and Semikron, as well
as driver circuits made up of discrete devices.
Generally, our products enable customers to design power converters with total bill-of-materials (BOM)
costs similar to those of competing alternatives. As a result, the value of our products is influenced by the prices
of discrete components, which fluctuate in relation to market demand, raw-material prices and other factors, but
have generally decreased over time.
While we vary the pricing of our ICs in response to fluctuations in prices of alternative solutions, we also
compete based on a variety of other factors. Most importantly, the highly integrated nature of our products enables
designs that utilize fewer total components than comparable discrete designs or designs using other integrated or
hybrid products. This enables power converters to be designed more quickly and manufactured more efficiently
and reliably than competing designs. We also compete on the basis of product functionality such as safety features
and energy-efficiency features and on the basis of the technical support we provide to our customers. This support
includes hands-on design assistance as well as a range of design tools and documentation such as software and
reference designs. We also believe that our record of product quality and history of delivering products to our
customers on a timely basis serve as additional competitive advantages.
Warranty
We generally warrant that our products will substantially conform to the published specifications for 12
months from the date of shipment. Under the terms of our purchase orders, our liability is limited generally to
either a credit equal to the purchase price or replacement of the defective part.

Item 1A. Risk Factors.
In addition to the other information in this report, the following factors should be considered carefully
in evaluating our business before purchasing shares of our stock.
Our operating results are volatile and difficult to predict. If we fail to meet the expectations of public
market analysts or investors, the market price of our common stock may decrease significantly. Our net revenues
and operating results have varied significantly in the past, are difficult to forecast, are subject to numerous factors
both within and outside of our control, and may fluctuate significantly in the future. As a result, our operating
results could fall below the expectations of public market analysts or investors. If that occurs, the price of our
stock may decline.
Some of the factors that could affect our operating results include the following:
•
•
•
•
•
•
•
•
•
•
•
•
•
•
•
the demand for our products declining in the major end markets we serve, which may occur due to
competitive factors, supply-chain fluctuations or changes in macroeconomic conditions;
our products are sold through distributors, which limits our direct interaction with our end customers,
which reduces our ability to forecast sales and increases the complexity of our business;
competitive pressures on selling prices;
the ability of our products to penetrate additional markets;
the volume and timing of orders received from customers;
the inability to adequately protect or enforce our intellectual property rights;
reliance on international sales activities for a substantial portion of our net revenues;
fluctuations in exchange rates, particularly the exchange rate between the U.S. dollar and the Japanese
yen, the Euro and the Swiss franc;
expenses we are required to incur (or choose to incur) in connection with our intellectual property
litigations;
the volume and timing of delivery of orders placed by us with our wafer foundries and assembly
subcontractors, and their ability to procure materials;
our ability to develop and bring to market new products and technologies on a timely basis;
earthquakes, terrorists acts or other disasters;
continued impact of changes in securities laws and regulations, including potential risks resulting from
our evaluation of our internal controls over financial reporting;
the lengthy timing of our sales cycle;
undetected defects and failures in meeting the exact specifications required by our products;
15
•
•
•
•
•
•
•
audits by the Internal Revenue Service, and potential future changes in tax laws may increase the amount
of taxes we are required to pay;
our ability to attract and retain qualified personnel;
risks associated with acquisitions and strategic investments;
our ability to successfully integrate, or realize the expected benefits from, our acquisitions;
changes in environmental laws and regulations, including with respect to energy consumption and climate
change;
interruptions in our information technology systems; and
uncertainties arising out of economic consequences of current and potential military actions or terrorist
activities and associated political instability.
If demand for our products declines in our major end markets, our net revenues will decrease. A limited
number of applications of our products, such as cellphone chargers, LED lights, desktop PCs and consumer
appliances make up a significant percentage of our net revenues. We expect that a significant level of our net
revenues and operating results will continue to be dependent upon these applications in the near term. The demand
for these products has been highly cyclical and has been impacted by economic downturns in the past. Any economic
slowdown in the end markets that we serve could cause a slowdown in demand for our ICs. When our customers
are not successful in maintaining high levels of demand for their products, their demand for our ICs decreases,
which adversely affects our operating results. Any significant downturn in demand in these markets would cause
our net revenues to decline and could cause the price of our stock to fall.
Our products are sold through distributors, which limits our direct interaction with our end customers,
therefore reducing our ability to forecast sales and increasing the complexity of our business. Sales to distributors
accounted for approximately 75% of net revenues in each of the years ended December 31, 2015, 2014 and 2013.
Selling through distributors reduces our ability to forecast sales and increases the complexity of our business,
requiring us to:
• manage a more complex supply chain;
• monitor the level of inventory of our products at each distributor, and
• monitor the financial condition and credit-worthiness of our distributors, many of which are located outside
of the United States and not publicly traded.
Since we have limited ability to forecast inventory levels at our end customers, it is possible that there
may be significant build-up of inventories in the distributor channel, with the OEM or the OEM’s contract
manufacturer. Such a buildup could result in a slowdown in orders, requests for returns from customers, or requests
to move out planned shipments. This could adversely impact our revenues and profits. Any failure to manage these
complexities could disrupt or reduce sales of our products and unfavorably impact our financial results.
Intense competition in the high-voltage power supply industry may lead to a decrease in our average
selling price and reduced sales volume of our products. The high-voltage power supply industry is intensely
competitive and characterized by significant price sensitivity. Our products face competition from alternative
technologies, such as linear transformers, discrete switcher power supplies, and other integrated and hybrid
solutions. If the price of competing solutions decreases significantly, the cost effectiveness of our products will be
adversely affected. If power requirements for applications in which our products are currently utilized go outside
the cost-effective range of our products, some of these alternative technologies can be used more cost effectively.
16
In addition, as our patents expire, our competitors could legally begin using the technology covered by the expired
patents in their products, potentially increasing the performance of their products and/or decreasing the cost of
their products, which may enable our competitors to compete more effectively. Our current patents may or may
not inhibit our competitors from getting any benefit from an expired patent. Our U.S. patents have expiration dates
ranging from 2016 to 2035. We cannot assure that our products will continue to compete favorably or that we will
be successful in the face of increasing competition from new products and enhancements introduced by existing
competitors or new companies entering this market. We believe our failure to compete successfully in the high-
voltage power supply business, including our ability to introduce new products with higher average selling prices,
would materially harm our operating results.
If our products do not penetrate additional markets, our business will not grow as we expect. We believe
that our future success depends in part upon our ability to penetrate additional markets for our products. We cannot
assure that we will be able to overcome the marketing or technological challenges necessary to penetrate additional
markets. To the extent that a competitor penetrates additional markets before we do, or takes market share from
us in our existing markets, our net revenues and financial condition could be materially adversely affected.
We do not have long-term contracts with any of our customers and if they fail to place, or if they cancel
or reschedule orders for our products, our operating results and our business may suffer. Our business is
characterized by short-term customer orders and shipment schedules, and the ordering patterns of some of our
large customers have been unpredictable in the past and will likely remain unpredictable in the future. Not only
does the volume of units ordered by particular customers vary substantially from period to period, but also purchase
orders received from particular customers often vary substantially from early oral estimates provided by those
customers for planning purposes. In addition, customer orders can be canceled or rescheduled without significant
penalty to the customer. In the past, we have experienced customer cancellations of substantial orders for reasons
beyond our control, and significant cancellations could occur again at any time. Also, a relatively small number
of distributors, OEMs and merchant power supply manufacturers account for a significant portion of our revenues.
Specifically, our top ten customers, including distributors, accounted for 60% of our net revenues in the year ended
December 31, 2015, and 59% in the year ended December 31, 2014. However, a significant portion of these
revenues are attributable to sales of our products through distributors of electronic components. These distributors
sell our products to a broad, diverse range of end users, including OEMs and merchant power supply manufacturers,
which mitigates the risk of customer concentration to a large degree.
If we are unable to adequately protect or enforce our intellectual property rights, we could lose market
share, incur costly litigation expenses, suffer incremental price erosion or lose valuable assets, any of which could
harm our operations and negatively impact our profitability. Our success depends upon our ability to continue our
technological innovation and protect our intellectual property, including patents, trade secrets, copyrights and
know-how. We are currently engaged in litigation to enforce our intellectual property rights, and associated expenses
have been, and are expected to remain, material and have adversely affected our operating results. We cannot assure
that the steps we have taken to protect our intellectual property will be adequate to prevent misappropriation, or
that others will not develop competitive technologies or products. From time to time, we have received, and we
may receive in the future, communications alleging possible infringement of patents or other intellectual property
rights of others. Costly litigation may be necessary to enforce our intellectual property rights or to defend us against
claimed infringement. The failure to obtain necessary licenses and other rights, and/or litigation arising out of
infringement claims could cause us to lose market share and harm our business.
As our patents expire, we will lose intellectual property protection previously afforded by those patents.
Additionally, the laws of some foreign countries in which our technology is or may in the future be licensed may
not protect our intellectual property rights to the same extent as the laws of the United States, thus limiting the
protections applicable to our technology.
Our international sales activities account for a substantial portion of our net revenues, which subjects
us to substantial risks. Sales to customers outside of the United States of America account for, and have accounted
17
for a large portion of our net revenues, including approximately 95% of our net revenues for the years ended
December 31, 2015, and 2014. If our international sales declined and we were unable to increase domestic sales,
our revenues would decline and our operating results would be harmed. International sales involve a number of
risks to us, including:
•
•
•
•
•
•
potential insolvency of international distributors and representatives;
reduced protection for intellectual property rights in some countries;
the impact of recessionary environments in economies outside the United States;
tariffs and other trade barriers and restrictions;
the burdens of complying with a variety of foreign and applicable U.S. Federal and state laws; and
foreign-currency exchange risk.
Our failure to adequately address these risks could reduce our international sales and materially and
adversely affect our operating results. Furthermore, because substantially all of our foreign sales are denominated
in U.S. dollars, increases in the value of the dollar cause the price of our products in foreign markets to rise, making
our products more expensive relative to competing products priced in local currencies.
Fluctuations in exchange rates, particularly the exchange rate between the U.S. dollar and the Japanese
yen, Swiss franc and Euro, may impact our gross margin and net income. Our exchange rate risk related to the
Japanese yen includes two of our major suppliers, Epson and Lapis, with which we have wafer supply agreements
based in U.S. dollars; however, these agreements also allow for mutual sharing of the impact of the exchange rate
fluctuation between Japanese yen and the U.S. dollar. Each year, our management and these suppliers review and
negotiate pricing; the negotiated pricing is denominated in U.S. dollars but is subject to contractual exchange rate
provisions. The fluctuation in the exchange rate is shared equally between Power Integrations and each of these
suppliers. We completed the acquisition of Concept (located in Biel, Switzerland) in the second quarter of 2012.
We maintain cash denominated in Swiss francs and euros to fund the operations of our Swiss subsidiary. The
functional currency of our Swiss subsidiary is the U.S. dollar; gains and losses arising from the re-measurement
of non-functional currency balances are recorded in other income in our consolidated statements of income, and
material unfavorable exchange-rate fluctuations with the Swiss franc could negatively impact our net income.
If we do not prevail in our litigation, we will have expended significant financial resources, potentially
without any benefit, and may also suffer the loss of rights to use some technologies. We are currently involved in
a number of patent litigation matters and the outcome of the litigation is uncertain. See Note 10, Legal Proceedings
and Contingencies, in our Notes to Consolidated Financial Statements included in this Form 10-K. For example,
in one of our patent suits the infringing company has been found to infringe four of our patents. Despite the favorable
court finding, the infringing party filed an appeal to the damages awarded. In another matter, we are being sued
in an ongoing case for patent infringement. Should we ultimately be determined to be infringing another party’s
patents, or if an injunction is issued against us while litigation is pending on those claims, such result could have
an adverse impact on our ability to sell products found to be infringing, either directly or indirectly. In the event
of an adverse outcome, we may be required to pay substantial damages, stop our manufacture, use, sale, or
importation of infringing products, or obtain licenses to the intellectual property we are found to have infringed.
We have also incurred, and expect to continue to incur, significant legal costs in conducting these lawsuits, including
the appeal of the case we won, and our involvement in this litigation and any future intellectual property litigation
could adversely affect sales and divert the efforts and attention of our technical and management personnel, whether
or not such litigation is resolved in our favor. Thus, even if we are successful in these lawsuits, the benefits of this
success may fail to outweigh the significant legal costs we will have incurred.
18
We depend on third-party suppliers to provide us with wafers for our products and if they fail to provide
us sufficient quantities of wafers, our business may suffer. Our primary supply arrangements for the production of
wafers are with Epson, Lapis, and X-FAB. Our contracts with these suppliers expire on varying dates, with the
earliest to expire in April 2018. Although some aspects of our relationships with Lapis, X-FAB and Epson are
contractual, many important aspects of these relationships depend on their continued cooperation. We cannot assure
that we will continue to work successfully with Epson, Lapis and X-FAB in the future, and that the wafer foundries’
capacity will meet our needs. Additionally, one or more of these wafer foundries could seek an early termination
of our wafer supply agreements. Any serious disruption in the supply of wafers from Epson, Lapis and X-FAB
could harm our business. We estimate that it would take 12 to 24 months from the time we identified an alternate
manufacturing source to produce wafers with acceptable manufacturing yields in sufficient quantities to meet our
needs.
Although we provide our foundries with rolling forecasts of our production requirements, their ability to
provide wafers to us is ultimately limited by the available capacity of the wafer foundry. Any reduction in wafer
foundry capacity available to us could require us to pay amounts in excess of contracted or anticipated amounts
for wafer deliveries or require us to make other concessions to meet our customers’ requirements, or may limit our
ability to meet demand for our products. Further, to the extent demand for our products exceeds wafer foundry
capacity, this could inhibit us from expanding our business and harm relationships with our customers. Any of
these concessions or limitations could harm our business.
If our third-party suppliers and independent subcontractors do not produce our wafers and assemble our
finished products at acceptable yields, our net revenues may decline. We depend on independent foundries to
produce wafers, and independent subcontractors to assemble and test finished products, at acceptable yields and
to deliver them to us in a timely manner. The failure of the foundries to supply us wafers at acceptable yields could
prevent us from selling our products to our customers and would likely cause a decline in our net revenues and
gross margin. In addition, our IC assembly process requires our manufacturers to use a high-voltage molding
compound that has been available from only a few suppliers. These compounds and their specified processing
conditions require a more exacting level of process control than normally required for standard IC packages.
Unavailability of assembly materials or problems with the assembly process can materially and adversely affect
yields, timely delivery and cost to manufacture. We may not be able to maintain acceptable yields in the future.
In addition, if prices for commodities used in our products increase significantly, raw material costs would
increase for our suppliers which could result in an increase in the prices our suppliers charge us. To the extent we
are not able to pass these costs on to our customers; this would have an adverse effect on our gross margins.
If our efforts to enhance existing products and introduce new products are not successful, we may not be
able to generate demand for our products. Our success depends in significant part upon our ability to develop new
ICs for high-voltage power conversion for existing and new markets, to introduce these products in a timely manner
and to have these products selected for design into products of leading manufacturers. New product introduction
schedules are subject to the risks and uncertainties that typically accompany development and delivery of complex
technologies to the market place, including product development delays and defects. If we fail to develop and sell
new products in a timely manner then our net revenues could decline.
In addition, we cannot be sure that we will be able to adjust to changing market demands as quickly and
cost-effectively as necessary to compete successfully. Furthermore, we cannot assure that we will be able to
introduce new products in a timely and cost-effective manner or in sufficient quantities to meet customer demand
or that these products will achieve market acceptance. Our failure, or our customers’ failure, to develop and introduce
new products successfully and in a timely manner would harm our business. In addition, customers may defer or
return orders for existing products in response to the introduction of new products. When a potential liability exists
we will maintain reserves for customer returns, however we cannot assure that these reserves will be adequate.
19
In the event of an earthquake, terrorist act or other disaster, our operations may be interrupted and our
business would be harmed. Our principal executive offices and operating facilities are situated near San Francisco,
California, and most of our major suppliers, which are wafer foundries and assembly houses, are located in areas
that have been subject to severe earthquakes, such as Japan. Many of our suppliers are also susceptible to other
disasters such as tropical storms, typhoons or tsunamis. In the event of a disaster, such as the earthquake and
tsunami in Japan, we or one or more of our major suppliers may be temporarily unable to continue operations and
may suffer significant property damage. Any interruption in our ability or that of our major suppliers to continue
operations could delay the development and shipment of our products and have a substantial negative impact on
our financial results.
Securities laws and regulations, including potential risk resulting from our evaluation of internal controls
over financial reporting, will continue to impact our results. Complying with the requirements of the federal
securities laws and NASDAQ’s conditions for continued listing have imposed significant legal and financial
compliance costs, and are expected to continue to impose significant costs and management burden on us. These
rules and regulations also may make it more expensive for us to obtain director and officer liability insurance, and
we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These rules
and regulations could also make it more difficult for us to attract and retain qualified executive officers and members
of our board of directors, particularly qualified members to serve on our audit committee. Further, the rules and
regulations under the Dodd-Frank Wall Street Reform and Consumer Protection Act, which became effective in
2011, may impose significant costs and management burden on us.
Additionally, because these laws, regulations and standards are expected to be subject to varying
interpretations, their application in practice may evolve over time as new guidance becomes available. This
evolution may result in continuing uncertainty regarding compliance matters and additional costs necessitated by
ongoing revisions to our disclosure and governance practices.
Because the sales cycle for our products can be lengthy, we may incur substantial expenses before we
generate significant revenues, if any. Our products are generally incorporated into a customer’s products at the
design stage. However, customer decisions to use our products, commonly referred to as design wins, can often
require us to expend significant research and development and sales and marketing resources without any assurance
of success. These significant research and development and sales and marketing resources often precede volume
sales, if any, by a year or more. The value of any design win will largely depend upon the commercial success of
the customer’s product. We cannot assure that we will continue to achieve design wins or that any design win will
result in future revenues. If a customer decides at the design stage not to incorporate our products into its product,
we may not have another opportunity for a design win with respect to that product for many months or years.
Our products must meet exacting specifications, and undetected defects and failures may occur which
may cause customers to return or stop buying our products. Our customers generally establish demanding
specifications for quality, performance and reliability, and our products must meet these specifications. ICs as
complex as those we sell often encounter development delays and may contain undetected defects or failures when
first introduced or after commencement of commercial shipments. We have from time to time in the past experienced
product quality, performance or reliability problems. If defects and failures occur in our products, we could
experience lost revenue, increased costs, including warranty expense and costs associated with customer support
and customer expenses, delays in or cancellations or rescheduling of orders or shipments and product returns or
discounts, any of which would harm our operating results.
Audits of our tax returns and potential future changes in tax laws may increase the amount of taxes we
are required to pay. Our operations are subject to income and transaction taxes in the United States and in multiple
foreign jurisdictions and to review or audit by the U.S. Internal Revenue Service (IRS) and state, local and foreign
tax authorities. In addition, the United States, countries in Asia and other countries where we do business have
been considering changes in relevant tax, accounting and other laws, regulations and interpretations, including
20
changes to tax laws applicable to multinational companies. These potential changes could adversely affect our
effective tax rates or result in other costs to us.
We must attract and retain qualified personnel to be successful and competition for qualified personnel
is intense in our market. Our success depends to a significant extent upon the continued service of our executive
officers and other key management and technical personnel, and on our ability to continue to attract, retain and
motivate qualified personnel, such as experienced analog design engineers and systems applications engineers.
The competition for these employees is intense, particularly in Silicon Valley. The loss of the services of one or
more of our engineers, executive officers or other key personnel could harm our business. In addition, if one or
more of these individuals leaves our employ, and we are unable to quickly and efficiently replace those individuals
with qualified personnel who can smoothly transition into their new roles, our business may suffer. We do not have
long-term employment contracts with, and we do not have in place key person life insurance policies on, any of
our employees.
We are exposed to risks associated with acquisitions and strategic investments. We have made, and in the
future intend to make, acquisitions of, and investments in, companies, technologies or products in existing, related
or new markets such as Concept. Acquisitions involve numerous risks, including but not limited to:
•
•
•
•
inability to realize anticipated benefits, which may occur due to any of the reasons described below, or
for other unanticipated reasons;
the risk of litigation or disputes with customers, suppliers, partners or stockholders of an acquisition target
arising from a proposed or completed transaction;
impairment of acquired intangible assets and goodwill as a result of changing business conditions,
technological advancements or worse-than-expected performance, which would adversely affect our
financial results; and
unknown, underestimated and/or undisclosed commitments, liabilities or issues not discovered in our due
diligence of such transactions.
We also in the future may have strategic relationships with other companies, which may decline in value
and/or not meet desired objectives. The success of these strategic relationships depends on various factors over
which we may have limited or no control and requires ongoing and effective cooperation with strategic partners.
Moreover, these relationships are often illiquid, such that it may be difficult or impossible for us to monetize such
relationships.
Our inability to successfully integrate, or realize the expected benefits from, our acquisitions could
adversely affect our results. We have made, and in the future intend to make, acquisitions of other businesses, such
as CamSemi and Concept, and with these acquisitions there is a risk that integration difficulties may cause us not
to realize expected benefits. The success of the acquisitions could depend, in part, on our ability to realize the
anticipated benefits and cost savings (if any) from combining the businesses of the acquired companies and our
business, which may take longer to realize than expected.
Changes in environmental laws and regulations may increase our costs related to obsolete products in
our existing inventory. Changing environmental regulations and the timetable to implement them continue to
impact our customers’ demand for our products. As a result there could be an increase in our inventory obsolescence
costs for products manufactured prior to our customers’ adoption of new regulations. Currently we have limited
visibility into our customers’ strategies to implement these changing environmental regulations into their business.
The inability to accurately determine our customers’ strategies could increase our inventory costs related to
obsolescence.
21
Interruptions in our information technology systems could adversely affect our business. We rely on the
efficient and uninterrupted operation of complex information technology systems and networks to operate our
business. Any significant system or network disruption, including but not limited to new system implementations,
computer viruses, security breaches, or energy blackouts could have a material adverse impact on our operations,
sales and operating results. We have implemented measures to manage our risks related to such disruptions, but
such disruptions could still occur and negatively impact our operations and financial results. In addition, we may
incur additional costs to remedy any damages caused by these disruptions or security breaches.
Uncertainties arising out of economic consequences of current and potential military actions or terrorist
activities and associated political instability could adversely affect our business. Like other U.S. companies, our
business and operating results are subject to uncertainties arising out of economic consequences of current and
potential military actions or terrorist activities and associated political instability, and the impact of heightened
security concerns on domestic and international travel and commerce. These uncertainties could also lead to delays
or cancellations of customer orders, a general decrease in corporate spending or our inability to effectively market
and sell our products. Any of these results could substantially harm our business and results of operations, causing
a decrease in our revenues.
Item 1B. Unresolved Staff Comments.
Not applicable.
Item 2. Properties.
We own our principal executive, administrative, manufacturing and technical offices which are located
in San Jose, California. We also own an R&D facility in New Jersey, which was purchased in 2010 in connection
with our acquisition of an early-stage R&D company, and a test facility in Biel, Switzerland which was acquired
in connection with our acquisition of Concept. We lease administrative office space in Singapore and Switzerland,
R&D facilities in Canada and the United Kingdom and a design center in Germany, in addition to sales offices in
various countries around the world to accommodate our sales force. We believe that our current facilities are
sufficient for our Company; however, if headcount increases above capacity we may need to lease additional space.

of directors authorized the use of an additional $30.0 million for the repurchase of our common stock, with
repurchases to be executed according to pre-defined price/volume guidelines. In the year ended December 31,
2015, we purchased 1.3 million shares for $53.7 million. As of December 31, 2015, we had $30.0 million available
for future stock repurchases. Authorization of future repurchase programs is at the discretion of the board of directors
and will depend on our financial condition, results of operations, capital requirements, business conditions as well
as other factors.
We did not repurchase any of our common stock during the fourth quarter of fiscal 2015.

Item 6. Selected Financial Data.
The following selected consolidated financial data should be read in conjunction with ‘’Management’s
Discussion and Analysis of Financial Condition and Results of Operations’’ and the consolidated financial
statements and the notes thereto included elsewhere in this Form 10-K to fully understand factors that may affect
the comparability of the information presented below. The selected consolidated financial data for each of the
years ended December 31, 2015, 2014 and 2013 are derived from our audited consolidated financial statements,
and accompanying notes, included in this Annual Report on Form 10-K. The selected consolidated statement of
income (loss) data for each of the years ended December 31, 2012 and 2011 and the consolidated balance sheet
data as of December 31, 2013, 2012 and 2011 are derived from our audited consolidated financial statements
which are not included in this report. Our historical results are not necessarily indicative of results for any future
period. In 2012, our net loss was affected by the impairment charges related our investment in SemiSouth
Laboratories, and from our settlement with the IRS related to the examination of our tax returns for the years
2003 through 2006. In 2012, we acquired CT Concept Technologie AG (Concept), a Swiss company. In 2015,
we acquired Cambridge Semiconductor Limited (CamSemi), a UK company (refer to Note 11, Acquisitions, in

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.
The following discussion and analysis of our financial condition and results of our operations should be
read in conjunction with the consolidated financial statements and the notes to those statements included elsewhere
in this Annual Report on Form 10-K. This discussion contains forward-looking statements that involve risks and
uncertainties. See “Cautionary Note Regarding Forward-Looking Statements” at the beginning of this Form 10-
K. Our actual results could differ materially from those contained in these forward-looking statements due to a
number of factors, including those discussed in Part I, Item 1A “Risk Factors” and elsewhere in this report.
Business Overview
We design, develop and market analog and mixed-signal integrated circuits (ICs) and other electronic
components and circuitry used in high-voltage power conversion. Our products are used in power converters that
convert electricity from a high-voltage source (typically 48 volts or higher) to the type of power required for a
specified downstream use. In most cases, this conversion entails, among other functions, converting alternating
current (AC) to direct current (DC) or vice versa, reducing or increasing the voltage, and regulating the output
voltage and/or current according to the customer’s specifications.
A large percentage of our products are ICs used in AC-DC power supplies, which convert the high-voltage
AC from a wall outlet to the low-voltage DC required by most electronic devices. Power supplies incorporating
our products are used with all manner of electronic products including mobile phones, computers, entertainment
and networking equipment, appliances, electronic utility meters, industrial controls and LED lights.
Since our May 2012 acquisition of CT-Concept Technologies AG (Concept), we also offer insulated-gate
bipolar transistor (IGBT) drivers - circuit boards containing multiple ICs, electrical isolation components and other
circuitry - used to operate arrays of high-voltage, high-power transistors known as IGBT modules. These driver/
module combinations are used for power conversion in high-power applications (i.e., power levels ranging from
tens of kilowatts up to one gigawatt) such as industrial motors, solar- and wind-power systems, electric vehicles
and high-voltage DC transmission systems.
Our net revenues were $344.0 million, $348.8 million and $347.1 million in 2015, 2014 and 2013,
respectively. In 2015 revenues decreased by $4.8 million due primarily to lower unit sales into the computer end-
market, reflecting reduced demand for power supplies for desktop computers, and the industrial end-market,
reflecting a broad-based slowdown in demand from the industrial sector of the economy. These reductions were
partially offset by higher unit sales into the communications end-market, largely as a result of the success of our
InnoSwitch products in mobile-device chargers and by the effect of our acquisition of Cambridge Semiconductor
Limited (CamSemi), whose products are used primarily in the communications end-market. In 2014 revenue
increased by $1.7 million, due primarily to growth in three of our primary end-market categories (consumer,
industrial and computer), driven by higher unit sales for a range of applications including consumer appliances,
industrial motor drives and desktop computers. The increase was partially offset by lower sales into the
communications end market due primarily to lower unit sales for residential-networking applications and cellphone
chargers.
Our top ten customers, including distributors that resell to OEMs and merchant power supply
manufacturers, accounted for 60% of our net revenues for 2015 and 59% for each of 2014 and 2013. Our top two
customers, both distributors of our products, collectively accounted for approximately 31% of our net revenues
for 2015 and 28% in both 2014 and 2013. In each of 2015, 2014 and 2013, international sales made up 95% of
net revenues.
Because our industry is intensely price-sensitive, our gross margin (gross profit divided by net revenues)
is subject to change based on the relative pricing of solutions that compete with ours. Variations in product mix,
end-market mix and customer mix can also cause our gross margin to fluctuate. Also, because we purchase a large
26
percentage of our silicon wafers from foundries located in Japan, our gross margin is influenced by fluctuations
in the exchange rate between the U.S. dollar and the Japanese yen. All else being equal, a 10% change in the value
of the U.S. dollar compared to the Japanese yen would eventually result in a corresponding change in our gross
margin of approximately 0.8% to 1.0%; this sensitivity may increase or decrease depending on the percentage of
our wafer supply that we purchase from Japanese suppliers. Also, although our wafer fabrication and assembly
operations are outsourced, as are most of our test operations, a portion of our production costs are fixed in nature.
As a result, our unit costs and gross profit margin are impacted by the volume of units we produce.
Our gross profit, defined as net revenues less cost of revenues, was $173.4 million, or 50% of net revenues,
in 2015, compared to $189.6 million, or 54% of net revenues in 2014, and $183.2 million, or 53% of net revenues,
in 2013. The decrease in gross margin in 2015 was due primarily to an unfavorable change in end-market mix,
with a greater percentage of revenue coming from lower-margin end-markets. In addition, we incurred higher
period costs resulting from the amortization of intangibles and inventory write-up related to our acquisition of
CamSemi, which took place in the first quarter of 2015 (refer to Note 11, Acquisitions, in our Notes to Consolidated
Financial Statements, for details). The increase in 2014 was due primarily to: a favorable end-market mix, with a
greater percentage of revenue coming from higher-margin end markets; a decline in the value of the Japanese yen
versus the U.S. dollar, which decreased the cost of silicon wafers purchased from our Japanese wafer-fabrication
foundries; and unit-cost benefits resulting from higher production volumes.
Total operating expenses in 2015, 2014 and 2013 were $134.4 million, $133.8 million and $129.2 million,
respectively. The increase in operating expenses in 2015 was driven primarily by the addition of employees in
connection with our acquisition of CamSemi (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial
Statements, for details); the increase in headcount caused a corresponding increase in salary and other employee-
related expenses. Sales and marketing expenses decreased, due primarily to a decrease in amortization of intangible
assets, as our Concept trade name was fully amortized as of the second quarter of 2014, and lower advertising and
promotional expenses in 2015. Operating expenses increased in 2014 compared to 2013 as a result of higher R&D
expenses, including increased headcount as well as greater engineering-materials and equipment-depreciation
expenses, all in support of our product-development efforts. Sales and marketing expenses also increased, due
primarily to the expansion of our sales and application-support staffs, which resulted in higher salary and related
expenses.
Critical Accounting Policies and Estimates
The preparation of financial statements and related disclosures in conformity with accounting principles
generally accepted in the United States of America, or U.S. GAAP, requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and
liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the
reporting period. On an ongoing basis, we evaluate our estimates, including those listed below. We base our
estimates on historical facts and various other assumptions that we believe to be reasonable at the time the estimates
are made. Actual results could differ from those estimates.
Our critical accounting policies are as follows:
•
•
•
•
•
•
revenue recognition;
stock-based compensation;
estimating write-downs for excess and obsolete inventory;
income taxes;
business combinations; and
goodwill and intangible assets.
Our critical accounting policies are important to the portrayal of our financial condition and results of
operations, and require us to make judgments and estimates about matters that are inherently uncertain. A brief
27
description of these critical accounting policies is set forth below. For more information regarding our accounting
policies, see Note 2, Summary of Significant Accounting Policies, in our Notes to Consolidated Financial Statements.
Revenue recognition
Product revenues consist of sales to original equipment manufacturers, or OEMs, merchant power supply
manufacturers and distributors. Approximately 75% of our net product sales were made to distributors in 2015.
We apply the provisions of Accounting Standards Codification (ASC) 605-10, Revenue Recognition, and all related
appropriate guidance. Revenue is recognized when all of the following criteria have been met: (1) persuasive
evidence of an arrangement exists, (2) delivery has occurred, (3) the price is fixed or determinable, and
(4) collectability is reasonably assured. Customer purchase orders are generally used to determine the existence
of an arrangement. Delivery is considered to have occurred when title and risk of loss have transferred to our
customer. We evaluate whether the price is fixed or determinable based on the payment terms associated with the
transaction and whether the sales price is subject to refund or adjustment. With respect to collectability, we perform
credit checks for new customers and perform ongoing evaluations of our existing customers’ financial condition
and require letters of credit whenever deemed necessary.
Sales to international OEMs and merchant power supply manufacturers for shipments from our facility
outside of the United States are pursuant to EX Works, or EXW, shipping terms, meaning that title to the product
transfers to the customer upon shipment from our foreign warehouse. Sales to international OEM customers and
merchant power supply manufacturers that are shipped from our facility in California are pursuant to Delivered at
Frontier, or DAF, shipping terms. As such, title to the product passes to the customer when the shipment reaches
the destination country and revenue is recognized upon the arrival of the product in that country. Shipments to
OEMs and merchant power supply manufacturers in the Americas are pursuant to Free on Board, or FOB, point
of origin shipping terms meaning that title is passed to the customer upon shipment. Revenue is recognized upon
title transfer for sales to OEMs and merchant power supply manufacturers, assuming all other criteria for revenue
recognition are met.
Sales to most distributors are made under terms allowing certain price adjustments and rights of return
on our products held by the distributors. As a result of these rights, we defer the recognition of revenue and the
costs of revenues derived from sales to these distributors until our distributors report that they have sold our products
to their customers. Our recognition of such distributor sell-through is based on point of sales reports received from
the distributor, at which time the price is no longer subject to adjustment and is fixed, and the products are no
longer subject to return to us except pursuant to warranty terms. The gross profit that is deferred upon shipment
to the distributor is reflected as “deferred income on sales to distributors” in the accompanying consolidated balance
sheets. The total deferred revenue as of December 31, 2015 and 2014, was approximately $25.7 million and $25.0
million, respectively. The total deferred cost as of December 31, 2015 and 2014, was approximately $10.6 million
and $9.8 million, respectively.
Frequently, distributors need to sell at a price lower than the standard distribution price in order to win
business. At the time the distributor invoices its customer or soon thereafter, the distributor submits a “ship and
debit” price adjustment claim to us to adjust the distributor’s cost from the standard price to the pre-approved lower
price. After we verify that the claim was pre-approved, a credit memo is issued to the distributor for the ship and
debit claim. We maintain a reserve for these unprocessed claims and for estimated future ship and debit price
adjustments. The reserves appear as a reduction to accounts receivable and deferred income on sales to distributors
in our accompanying consolidated balance sheets. To the extent future ship and debit claims significantly exceed
amounts estimated, there could be a material impact on the deferred revenue and deferred margin ultimately
recognized. To evaluate the adequacy of our reserves, we analyze historical ship and debit payments and levels
of inventory in the distributor channels.
28
Sales to certain of our distributors are made under terms that do not include rights of return or price
concessions after the product is shipped to the distributor. Accordingly, product revenue is recognized upon
shipment and title transfer assuming all other revenue recognition criteria are met.
Stock-based compensation
We apply the provisions of ASC 718-10, Share-Based Payment. Under the provisions of ASC 718-10,
we recognize the fair value of stock-based compensation in our financial statements over the requisite service
period of the individual grants, which generally equals a four-year vesting period. We use estimates of volatility,
expected term, risk-free interest rate, dividend yield and forfeitures in determining the fair value of these awards
and the amount of compensation expense to recognize. Changes in the estimated forfeiture rate could result in
changes to our current compensation charges for historical grants.
Estimating write-downs for excess and obsolete inventory
When evaluating the adequacy of our valuation adjustments for excess and obsolete inventory, we identify
excess and obsolete products and also analyze historical usage, forecasted production based on demand forecasts,
current economic trends and historical write-offs. This write-down is reflected as a reduction to inventory in the
consolidated balance sheets and an increase in cost of revenues. If actual market conditions are less favorable than
our assumptions, we may be required to take additional write-downs, which could adversely impact our cost of
revenues and operating results.
Income taxes
Income tax expense is an estimate of current income taxes payable or refundable in the current fiscal year
based on reported income before income taxes. Deferred income taxes reflect the effect of temporary differences
and carry-forwards that are recognized for financial reporting and income tax purposes.
We account for income taxes under the provisions of ASC 740, Income Taxes. Under the provisions of
ASC 740, deferred tax assets and liabilities are recognized based on the differences between the financial statement
carrying amounts of existing assets and liabilities and their respective tax bases, utilizing the tax rates that are
expected to apply to taxable income in the years in which those temporary differences are expected to be recovered
or settled. We recognize valuation allowances to reduce any deferred tax assets to the amount that we estimate will
more likely than not be realized based on available evidence and management’s judgment. We limit the deferred
tax assets recognized related to some of our officers’ compensation to amounts that we estimate will be deductible
in future periods based upon Internal Revenue Code Section 162(m). In the event that we determine, based on
available evidence and management judgment, that all or part of the net deferred tax assets will not be realized in
the future, we would record a valuation allowance in the period the determination is made. In addition, the calculation
of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex
tax laws. Resolution of these uncertainties in a manner inconsistent with our expectations could have a material
impact on our results of operations and financial position.
As of December 31, 2015, we continue to maintain a valuation allowance on our California deferred tax
assets as we believe that it is not more likely than not that the deferred tax assets will be fully realized. We also
maintain a valuation allowance with respect to some of our deferred tax assets relating primarily to tax credits in
Canada and the state of New Jersey as well as Federal capital loss carryforwards.
Business combinations
The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed
based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair
value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated
29
to goodwill. We determine the estimated fair values after review and consideration of relevant information, including
discounted cash flows, quoted market prices and estimates made by management. We adjust the preliminary
purchase price allocation, as necessary, during the measurement period of up to one year after the acquisition
closing date as we obtain more information as to facts and circumstances existing at the acquisition date impacting
asset valuations and liabilities assumed. Acquisition-related costs are recognized separately from the acquisition
and are expensed as incurred.
Goodwill and intangible assets
In accordance with ASC 350-10, Goodwill and Other Intangible Assets, we evaluate goodwill for
impairment on an annual basis, or as other indicators of impairment emerge. The provisions of ASC 350-10 require
that we perform a two-step impairment test. In the first step, we compare the implied fair value of our single
reporting unit to its carrying value, including goodwill. If the fair value of our reporting unit exceeds the carrying
amount no impairment adjustment is required. If the carrying amount of our reporting unit exceeds the fair value,
step two will be completed to measure the amount of goodwill impairment loss, if any exists. If the carrying value
of our single reporting unit’s goodwill exceeds its implied fair value, then we record an impairment loss equal to
the difference, but not in excess of the carrying amount of the goodwill. Under the amendments of ASC 350-10,
Accounting Standards Update (ASU) 2011-08, Testing Goodwill for Impairment, we have the option to first assess
qualitative factors to determine whether the existence of events or circumstances leads to a determination that it
is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, we elect this option
and after assessing the totality of events or circumstances, we determine it is not more likely than not that the fair
value of a reporting unit is less than its carrying amount, then performing the two-step impairment test is unnecessary.
We have not elected this option to date. We evaluated goodwill for impairment in the fourth quarters of 2015 and
2014, and concluded that no impairment existed as of December 31, 2015, and December 31, 2014.
ASC 350-10 also requires that intangible assets with estimable useful lives be amortized over their
respective estimated useful lives, and reviewed for impairment in accordance with ASC 360-10, Accounting for
the Impairment or Disposal of Long-Lived Assets. We review long-lived assets, such as acquired intangibles and
property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying
amount of an asset may not be recoverable. We measure recoverability of assets to be held and used by a comparison
of the carrying amount of an asset to estimated undiscounted future cash flows expected to be generated by the
asset. If the carrying amount of an asset exceeds its estimated future cash flows, we recognize an impairment charge
by the amount by which the carrying amount of the asset exceeds the fair value of the asset.

Comparison of Years Ended December 31, 2015, 2014 and 2013
Net revenues. Net revenues consist of revenues from product sales, which are calculated net of returns
and allowances. In 2015 revenues decreased by $4.8 million, due primarily to lower unit sales into the computer
end-market, reflecting reduced demand for power supplies for desktop computers, and the industrial end-market,
reflecting a broad-based slowdown in demand from the industrial sector of the economy. These reductions were
partially offset by higher unit sales into the communications end-market, largely as a result of the success of our
InnoSwitch products in mobile-device chargers and by the effect of our acquisition of CamSemi, whose products
are used primarily in the communications end-market.
In 2014 revenue increased by $1.7 million, due primarily to growth in three of our primary end-market
categories (consumer, industrial and computer), driven by higher unit sales for a range of applications including
consumer appliances, industrial motor drives and desktop computers. The increase was partially offset by lower
sales into the communications end market due primarily to lower unit sales for residential-networking applications
and cellphone chargers.
Our net revenue mix by the end markets served in 2015, 2014 and 2013 were as follows:

Sales to customers outside of the United States were $327.5 million in 2015, compared to $332.8 million
in 2014 and $328.5 million in 2013, representing approximately 95% of net revenues in each of 2015, 2014 and
2013. Although power supplies using our products are designed and distributed worldwide, most of these power
supplies are manufactured by our customers in Asia. As a result, sales to this region accounted for approximately
80% of our net revenues in each of 2015 and 2014 and 81% in 2013. We expect international sales to continue to
account for a large portion of our net revenues for the foreseeable future.
Distributors accounted for 75% of our net product sales for each of the years ended December 31, 2015,
2014 and 2013, with direct sales to OEMs and power supply manufacturers accounting for the remainder in each
of the corresponding years. In 2015 two distributors accounted for more than 10% of revenues. In each of 2014
and 2013, one distributor accounted for more than 10% of revenues. The following customers each accounted for
10% or more of net revenues during these years:

Gross profit. Gross profit is net revenues less cost of revenues. Our cost of revenues consists primarily
of the purchase of wafers from our contracted foundries, the assembly, packaging and testing of our products by
sub-contractors, product testing performed in our own facility, overhead associated with the management of our
supply chain and the amortization of acquired intangible assets. Gross margin is gross profit divided by net revenues.

The decrease in gross margin from 2014 to 2015 was due primarily to an unfavorable change in end-
market mix, with a greater percentage of revenue coming from lower-margin end-markets. In addition, we incurred
higher period costs resulting from the amortization of intangibles and inventory write-up related to our acquisition
of CamSemi, which took place in the first quarter of 2015 (refer to Note 11, Acquisitions, in our Notes to Consolidated
Financial Statements, for details). The increase in gross margin from 2013 to 2014 was due primarily to: a favorable
end-market mix, with a greater percentage of revenue coming from higher-margin end markets; a continued decline
in the value of the Japanese yen versus the U.S. dollar, which decreased the cost of silicon wafers purchased from
our Japanese wafer-fabrication foundries; and unit cost benefits from higher production volumes.
Research and development expenses. R&D expenses consist primarily of employee-related expenses
including stock-based compensation and expensed material and facility costs associated with the development of
new processes and new products. We also record R&D expenses for prototype wafers related to new products
until the products are released to production. The table below compares R&D expenses for the years ended

R&D expenses increased in 2015 as compared to 2014, driven primarily by the addition of employees in
connection with our acquisition of CamSemi (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial
Statements, for details); the increase in headcount caused a corresponding increase in salary and other employee-
related expenses. R&D expenses increased in 2014 compared to 2013, driven primarily by increased payroll and
related expenses as a result of increased headcount, due mainly to the expansion of our product-development
efforts. We also increased outside-service expenses related to product design and development. These increases
were partially offset by lower stock-based compensation expense, reflecting the fact that our 2014 performance-
based stock awards failed to vest due to our 2014 performance.
Sales and marketing expenses. Sales and marketing expenses consist primarily of employee-related
expenses, including stock-based compensation, commissions to sales representatives, amortization of acquired
intangible assets and facilities expenses, including expenses associated with our regional sales and support offices.

Sales and marketing expenses decreased in 2015 compared to 2014 due primarily to lower amortization
of acquisition-related intangible assets, as our Concept trade name was fully amortized in the second quarter of
2014 and also due to lower advertising and promotional expenses in 2015. Sales and marketing expenses increased
in 2014 compared to 2013, due primarily to increased salary and related expenses reflecting the expansion of our
sales and application-support staffs. This increase was partially offset by lower amortization of acquisition-related
intangible assets, as our Concept trade name was fully amortized in the second quarter of 2014.
General and administrative expenses. General and administrative, or G&A, expenses consist primarily
of employee-related expenses, including stock-based compensation expenses for administration, finance, human
resources and general management, as well as consulting, professional services, legal and auditing expenses. The

G&A expenses decreased in 2015 compared to 2014 due primarily to a decrease in legal expenses as a
result of lower litigation fees in connection with our Fairchild litigation and decreased outside service fees relating
to our CamSemi acquisition completed in January 2015, partially offset by higher patent attorney spending. G&A
expenses decreased in 2014 compared to 2013 due primarily to lower stock-based compensation expense, reflecting
the fact that our 2014 performance-based stock awards failed to vest due to our 2014 performance. In addition, we
incurred lower legal expenses as a result of lower patent fees and general legal fees, partially offset by increased
outside service fees related to our acquisition in January 2015 of CamSemi, a UK company (refer to Note 11,
Acquisitions, in our Notes to Consolidated Financial Statements for details).
Other income, net. Other income, net consists primarily of interest income earned on cash and cash
equivalents, marketable securities and other investments, and the impact of foreign exchange gains or losses. The

Other income decreased in 2015 compared to 2014 due primarily to the unfavorable impact of foreign
currency movements relative to the U.S. dollar and the related loss recognized from the re-measurement of monetary
foreign currency assets and liabilities of our Swiss subsidiary. Other income decreased in 2014 compared to 2013
due to a 2013 gain realized for the sale of non-operating assets, partially offset by increased interest income in
2014.
Provision for (benefit from)income taxes. Provision for (benefit from) income taxes represents federal,

In 2015, our effective tax rate was impacted by the geographic distribution of our world-wide earnings
in lower tax jurisdictions and the federal R&D tax credit. In 2014, our effective tax rate was impacted by an
agreement reached with the United States Internal Revenue Service to conclude the examination of our income
tax returns for the years 2007 through 2009. The resolution of the audit resulted in a federal tax benefit to us of
$2.8 million; we also recorded a state tax benefit of $0.5 million. The one-time benefit included the reversal of
$4.1 million of related unrecognized tax benefits that had been recorded as non-current liabilities in our consolidated
balance sheets. Our effective tax rate for the year ended December 31, 2013, was favorably impacted by the
geographic distribution of our world-wide earnings and earnings in lower-tax jurisdictions. Additionally, the rate
was favorably impacted by federal research tax credits for 2015, 2014 and 2013.
Liquidity and Capital Resources
We had approximately $173.9 million in cash, cash equivalents and short-term marketable securities at
December 31, 2015, compared to $175.3 million at December 31, 2014, and $202.1 million at December 31,
2013. As of December 31, 2015, 2014 and 2013, we had working capital, defined as current assets less current
liabilities, of approximately $188.4 million, $210.8 million and $227.0 million, respectively.
On July 5, 2012, we entered into a Credit Agreement (Credit Agreement) with two banks. The Credit
Agreement provides us with a $100.0 million revolving line of credit to use for general corporate purposes with a
$20.0 million sub-limit for the issuance of standby and trade letters of credit. The Credit Agreement was amended
on April 1, 2014, to extend the Credit Agreement termination date from July 5, 2015, to April 1, 2017, with all
other terms of the Credit Agreement remaining the same. Our ability to borrow under the revolving line of credit
is conditioned upon our compliance with specified covenants, primarily a minimum cash requirement and a debt-
to-earnings ratio, with which we are currently in compliance. The Credit Agreement terminates on April 1, 2017,
and all advances under the revolving line of credit will become due on such date, or earlier in the event of a default.
As of December 31, 2015, we had no amounts outstanding under our agreement.
34
Our operating activities generated cash of $92.2 million, $85.6 million, and $98.7 million in the years
ended December 31, 2015, 2014 and 2013, respectively. In each of these years, cash was primarily generated from
operating activities in the ordinary course of business.
In 2015, our net income was $39.1 million, which included non-cash depreciation, amortization and stock-
based expenses of $16.5 million, $7.0 million and $14.8 million, respectively. Sources of cash also included: (1)
a $13.5 million decrease in inventory due to ongoing reduction efforts; (2) a $4.1 million decrease in accounts
receivable due to the timing of collections; and (3) a $3.4 million decrease in prepaid expenses and other assets
due to income tax refunds received during the period. These sources of cash were partially offset by a $5.4 million
increase in deferred taxes.
In 2014, our net income was $59.5 million, which included non-cash depreciation, amortization and stock-
based compensation expenses of $15.9 million, $6.1 million and $14.3 million, respectively. Sources of cash also
included: (1) a $8.2 million decrease in prepaid expenses and other assets as a result of lower payments related to
legal and R&D services, in addition to tax refunds received during the year; (2) a $2.1 million decrease in accounts
receivable as a result of lower sales in the fourth quarter of 2014 compared to 2013 and improved collections; and
(3) a $2.3 million increase in accounts payable due to the timing of payments. These sources of cash were partially
offset by a $21.7 million increase in our inventories as a result of lower-than expected sales, and by a $3.2 million
decrease in taxes payable.
In 2013, our net income was $57.3 million, which included non-cash depreciation, amortization and stock-
based compensation expenses of $16.1 million, $7.4 million and $16.5 million, respectively. Sources of cash also
included a $4.2 million increase in deferred income on sales to distributors, resulting from increased shipments to
distributors in the fourth quarter of 2013 compared to the same period of 2012. These sources of cash were partially
offset by a $4.9 million increase in accounts receivable resulting primarily from revenue growth in the fourth
quarter of 2013 compared to the same period in 2012.
Our investing activities in the year ended December 31, 2015, resulted in a net $7.7 million use of cash,
consisting primarily of $15.5 million in net cash paid for the acquisition of CamSemi, $10.4 million net cash paid
for a building purchase (refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements, for
details) and $11.4 million for purchases of property and equipment, primarily machinery and equipment for use
in the manufacture of our products. These uses of cash were partially offset by $29.6 million of proceeds from the
sale and maturity of marketable securities, net of purchases.
Our investing activities in the year ended December 31, 2014, resulted in a net $38.1 million use of cash,
consisting primarily of: (1) $7.2 million, net, for purchases of marketable securities; (2) $23.1 million for purchases
of property and equipment, primarily machinery and equipment for production and R&D; (3) $1.3 million for the
purchase of power.com, our domain name; and (4) a $6.6 million cash payment to CamSemi under a loan agreement
(refer to Note 11, Acquisitions, in our Notes to Consolidated Financial Statements, for further details).
Our investing activities in the year ended December 31, 2013, resulted in a net $90.7 million use of cash,
consisting primarily of $78.1 million, net, for purchases of marketable securities and $14.0 million for purchases
of property and equipment. Our investment in property and equipment included purchases of manufacturing and
R&D equipment, as well as an enterprise resource planning, or ERP, software upgrade and building improvements
to our San Jose, California facility.
Our financing activities in the year ended December 31, 2015, resulted in a net use of $55.1 million of
cash. Financing activities consisted primarily of $53.7 million for the repurchase of our common stock and $13.9
million for the payment of dividends to stockholders, partially offset by proceeds of $12.6 million from the issuance
of common stock, including the exercise of employee stock options and the issuance of shares through our employee
stock purchase plan.
35
Our financing activities in the year ended December 31, 2014, resulted in a net use of $79.6 million of
cash, consisting primarily of $80.8 million for the repurchase of our common stock, and $13.2 million for the
payment of dividends to stockholders. The use of cash was partially offset by proceeds of $13.9 million from
issuance of common stock, including the exercise of employee stock options and the issuance of shares through
our employee stock purchase plan.
Our financing activities in the year ended December 31, 2013, resulted in net proceeds of $21.5 million
of cash, consisting primarily of $30.2 million from the issuance of common stock, including the exercise of employee
stock options and the issuance of shares through our employee stock purchase plan, partially offset by $9.4 million
for the payment of dividends to stockholders.
In January 2013, our board of directors declared four quarterly cash dividends in the amount of $0.08 per
share paid to stockholders of record at the end of each quarter in 2013. In October 2013, our board of directors
declared four quarterly cash dividends in the amount of $0.10 per share to be paid to stockholders of record at the
end of each quarter in 2014. In April 2014, our board of directors increased the quarterly dividends for the third
and fourth quarters of 2014 to $0.12 per share. In January 2015, our board of directors extended the $0.12 quarterly
dividend through each quarter in 2015.
In January 2016, our board of directors declared four quarterly cash dividends in the amount of $0.13 per
share to be paid to stockholders of record at the end of each quarter in 2016. The declaration of any future cash
dividend is at the discretion of the board of directors and will depend on our financial condition, results of operations,
capital requirements, business conditions and other factors, as well as a determination that cash dividends are in
the best interest of our stockholders.
In October 2012, our board of directors authorized the use of $50.0 million for the repurchase of our
common stock, and in the years ended December 31, 2014, and December 31, 2015, our board of directors authorized
the use of an additional $75.0 million and $60.0 million, respectively, for repurchase of our common stock, with
repurchases to be executed according to pre-defined price/volume guidelines. In the year ended December 31,
2015, we purchased 1.3 million shares for $53.7 million. In the year ended December 31, 2014, we purchased 1.6
million shares for $80.8 million. No shares were purchased during the year ended December 31, 2013, as the price
of our stock exceeded the pre-defined price guidelines throughout the year. As of December 31, 2015, we had
$30.0 million available for future stock repurchases. Authorization of future stock repurchase programs is at the
discretion of the board of directors and will depend on our financial condition, results of operations, capital
requirements, business conditions as well as other factors.
As of December 31, 2015, we had a contractual obligation related to income tax, consisting primarily of
unrecognized tax benefits of approximately $13.6 million. The tax obligation was classified as long-term income
taxes payable and a portion is recorded in deferred tax assets in our consolidated balance sheet.
In connection with our IRS settlements in 2014 and in 2012, we were entitled to repatriate $106.9 million
from our foreign subsidiary without incurring additional U.S. income tax (See Note 8, Provision for Income Taxes,
in our Notes to Consolidated Financial Statements).
Our cash, cash equivalents and investment balances may change in future periods due to changes in our
planned cash outlays, including changes in incremental costs such as direct and integration costs related to future
acquisitions. We expect continued sales growth in our foreign business and plan to use the earnings generated by
our foreign subsidiaries to continue to fund both the working capital and growth needs of our foreign entities, along
with providing funding for any future foreign acquisitions. We do not provide for U.S. taxes on our undistributed
earnings of foreign subsidiaries that we intend to invest indefinitely outside the U.S., unless such taxes are otherwise
required under U.S. tax law. Beginning in 2013, we determined that a portion of our foreign subsidiaries current
and future earnings may be remitted prospectively to the U.S. for domestic cash flow purposes and, accordingly,
provided for the related U.S. taxes in our consolidated financial statements. Currently the majority of our cash and
36
marketable securities are held in the U.S. If we change our intent to invest our undistributed earnings outside the
U.S. indefinitely or if a greater amount of undistributed earnings are needed for U.S. operations than previously
anticipated and for which U.S. taxes have not been recorded, we would be required to accrue or pay U.S. taxes
(subject to an adjustment for foreign tax credits, where applicable) and withholding taxes payable to various foreign
countries on some or all of these undistributed earnings. As of December 31, 2015, we had undistributed earnings
of foreign subsidiaries that are indefinitely invested outside of the U.S. of approximately $222.0 million.
If our operating results deteriorate in future periods, either as a result of a decrease in customer demand,
or severe pricing pressures from our customers or our competitors, or for other reasons, our ability to generate
positive cash flow from operations may be jeopardized. In that case, we may be forced to use our cash, cash
equivalents and short-term investments, use our current financing or seek additional financing from third parties
to fund our operations. We believe that cash generated from operations, together with existing sources of liquidity,
will satisfy our projected working capital and other cash requirements for at least the next 12 months.
Off-Balance Sheet Arrangements
As of December 31, 2015 and 2014, we did not have any off-balance sheet arrangements or relationships
with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or
special purpose entities, which are typically established for the purpose of facilitating off-balance sheet
arrangements or other contractually narrow or limited purposes.
Contractual Obligations
As of December 31, 2015, we had the following contractual obligations and commitments, consisting
solely of non-cancelable operating lease agreements:

million, and was classified as long-term income taxes payable and a portion is recorded in deferred tax assets in
our consolidated balance sheet.
Item 7A. Quantitative and Qualitative Disclosures About Market Risk.
Interest Rate Risk. Our exposure to market risk for changes in interest rates relates primarily to our
investment portfolio. We consider cash invested in highly liquid financial instruments with a remaining maturity
of three months or less at the date of purchase to be cash equivalents. Investments in highly liquid financial
instruments with maturities greater than three months are classified as short-term investments. We generally hold
securities until maturity; however, they may be sold under certain circumstances, including, but not limited to,
when necessary for the funding of acquisitions and other strategic investments. As a result of this policy, we
classify our investment portfolio as available-for-sale. We invest in high-credit quality issuers and, by policy, limit
the amount of credit exposure to any one issuer. As stated in our policy, we seek to ensure the safety and preservation
of our invested principal funds by limiting default risk, market risk and reinvestment risk. We mitigate default
risk by investing in safe and high-credit quality securities and by constantly positioning our portfolio to respond
appropriately to a significant reduction in a credit rating of any investment issuer, guarantor or depository. The
portfolio includes only marketable securities with active secondary or resale markets to facilitate portfolio liquidity.
At December 31, 2015 and 2014, we held primarily cash equivalents and short-term investments with fixed interest
rates. We do not hold any instruments for trading purposes.
37
Our investment securities are subject to market interest rate risk and will vary in value as market interest
rates fluctuate. To minimize market risk, we invest in high-credit quality issuers and, by policy, limit the amount
of credit exposure to any one issuer, and therefore if market interest rates were to increase or decrease by 10%
from interest rates as of December 31, 2015, or December 31, 2014, the increase or decrease in the fair market
value of our portfolio on these dates would not have been material. We monitor our investments for impairment
on a periodic basis. Refer to Note 2, Summary of Significant Accounting Policies, for a tabular presentation of our
available-for-sale investments and the expected maturity dates.
Foreign Currency Exchange Risk. As of December 31, 2015, our primary transactional currency was the
U.S. dollar; in addition, we hold cash in Swiss francs and euro as a result of our acquisition of Concept in 2012.
Cash balances held in foreign countries are subject to local banking laws and may bear higher or lower risk than
cash deposited in the United States. The following represents the potential impact on our pretax income from a
change in the value of the U.S. dollar compared to the Swiss franc and euro as of December 31, 2015. This sensitivity
analysis applies a change in the U.S. dollar value of 5% and 10%.

The foreign exchange rate fluctuation between the U.S. dollar versus the Swiss franc and euro is recorded
in other income in our consolidated statements of income.
We have sales offices in various other foreign countries in which our expenses are denominated in the
local currency, primary Asia and Western Europe. From time to time we may enter into foreign currency hedging
contracts to hedge certain foreign currency transactions. As of December 31, 2015, and December 31, 2014, we
did not have an open foreign currency hedge program utilizing foreign currency forward exchange contracts.
With two of our major suppliers, Seiko Epson Corporation, or Epson, and ROHM Lapis Semiconductor
Co., Ltd., or Lapis, we have wafer supply agreements based in U.S. dollars; however, our agreements with Epson
and Lapis also allow for mutual sharing of the impact of the exchange rate fluctuation between Japanese yen and
the U.S. dollar. Each year, our management and these suppliers review and negotiate pricing; the negotiated pricing
is denominated in U.S. dollars but is subject to contractual exchange rate provisions. The fluctuation in the exchange
rate is shared equally between us and each of these suppliers.
Nevertheless, as a result of our above-mentioned supplier agreements, our gross margin is influenced by
fluctuations in the exchange rate between the U.S. dollar and the Japanese yen. All else being equal, a 10% change
in the value of the U.S. dollar compared to the Japanese yen would result in a corresponding change in our gross
margin of approximately 0.8% to 1.0%; this sensitivity may increase or decrease depending on the percentage of
our wafer supply that we purchase from some of our Japanese suppliers and could subject our gross profit and
operating results to the potential for material fluctuations.
Item 8. Financial Statements and Supplementary Data.
The financial statements required by this item are set forth in the pages indicated in Item 15(a), and the
supplementary data required by this item is included in Note 14, Selected Quarterly Information, in our notes to
consolidated financial statements.

Item 9A. Controls and Procedures.
Evaluation of Disclosure Controls and Procedures
Management is required to evaluate our disclosure controls and procedures, as defined in Rule 13a-15(e)
under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Disclosure controls and procedures
are controls and other procedures designed to provide reasonable assurance that information required to be disclosed
in our reports filed under the Exchange Act, such as this Annual Report on Form 10-K, is recorded, processed,
summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and
forms. Disclosure controls and procedures include controls and procedures designed to provide reasonable
assurance that such information is accumulated and communicated to our management, including our Chief
Executive Officer and Chief Financial Officer as appropriate to allow timely decisions regarding required
disclosure. Our disclosure controls and procedures include components of our internal control over financial
reporting, which consists of control processes designed to provide reasonable assurance regarding the reliability
of our financial reporting and the preparation of financial statements in accordance with generally accepted
accounting principles in the U.S. To the extent that components of our internal control over financial reporting are
included within our disclosure controls and procedures, they are included in the scope of our periodic controls
evaluation. Based on our management's evaluation (with the participation of our principal executive officer and
principal financial officer), our principal executive officer and principal financial officer have concluded that our
disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) were
effective as of the end of the period covered by this report.
Management’s Report on Internal Control Over Financial Reporting
Management is responsible for establishing and maintaining adequate internal control over financial
reporting, as defined in Rule 13a-15(f) under the Exchange Act. Internal control over financial reporting is designed
to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial
statements for external reporting purposes in accordance with generally accepted accounting principles. Internal
control over financial reporting includes those policies and procedures that:
•
•
•
pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions
and dispositions of our assets;
provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting principles and that receipts and expenditures
are being made only in accordance with authorizations of our management and directors; and
provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use
or disposition of our assets that could have a material effect on the financial statements.
Internal control over financial reporting cannot provide absolute assurance of achieving financial reporting
objectives because of its inherent limitations. Internal control over financial reporting is a process that involves
human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human
failures. Because of such limitations, there is a risk that material misstatements may not be prevented or detected
on a timely basis by internal control over financial reporting.
Management conducted an assessment of Power Integrations' internal control over financial reporting as
of December 31, 2015, based on the framework established by the Committee of Sponsoring Organization (COSO)
of the Treadway Commission in Internal Control - Integrated Framework issued in 2013. Based on this assessment,
management concluded that, as of December 31, 2015, our internal control over financial reporting was effective.
39
The effectiveness of Power Integrations' internal control over financial reporting as of December 31,
2015, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in
their report which appears below.
Changes in Internal Control over Financial Reporting
There were no changes in our internal controls over financial reporting during the fourth quarter of 2015,
which were identified in connection with management’s evaluation required by paragraph (d) of Rules 13a-15 and
15d-15 under the Exchange Act, that have materially affected or are reasonably likely to materially affect our
internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of
Power Integrations, Inc.
San Jose, California
We have audited the internal control over financial reporting of Power Integrations, Inc. and subsidiaries
(the "Company") as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s
management is responsible for maintaining effective internal control over financial reporting and for its assessment
of the effectiveness of internal control over financial reporting, included in the accompanying Management’s
Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s
internal control over financial reporting based on our audit.
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance
about whether effective internal control over financial reporting was maintained in all material respects. Our audit
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinion.
A company’s internal control over financial reporting is a process designed by, or under the supervision
of, the company’s principal executive and principal financial officers, or persons performing similar functions,
and effected by the company’s Board of Directors, management, and other personnel to provide reasonable
assurance regarding the reliability of financial reporting and the preparation of financial statements for external
purposes in accordance with generally accepted accounting principles. A company’s internal control over financial
reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable
detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide
reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in
accordance with generally accepted accounting principles, and that receipts and expenditures of the company are
being made only in accordance with authorizations of management and directors of the company; and (3) provide
reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of
the company’s assets that could have a material effect on the financial statements.
Because of the inherent limitations of internal control over financial reporting, including the possibility
of collusion or improper management override of controls, material misstatements due to error or fraud may not
be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal
control over financial reporting to future periods are subject to the risk that the controls may become inadequate
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
In our opinion, the Company maintained, in all material respects, effective internal control over financial
reporting as of December 31, 2015, based on the criteria established in Internal Control - Integrated Framework
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight
Board (United States), the consolidated financial statements and consolidated financial statement schedule as of
and for the year ended December 31, 2015 of the Company and our report dated February 10, 2016 expressed an
unqualified opinion on those consolidated financial statements and consolidated financial statement schedule.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the Board of Directors and Stockholders of
Power Integrations, Inc.
San Jose, California
We have audited the accompanying consolidated balance sheets of Power Integrations, Inc. and
subsidiaries (the “Company”) as of December 31, 2015 and 2014, and the related consolidated statements of
income, comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended
December 31, 2015. Our audits also included the consolidated financial statement schedule listed in the Index at
Item 15 (a) 2. These consolidated financial statements and consolidated financial statement schedule are the
responsibility of the Company’s management. Our responsibility is to express an opinion on the consolidated
financial statements and consolidated financial statement schedule based on our audits.
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight
Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance
about whether the consolidated financial statements are free of material misstatement. An audit includes examining,
on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. An audit
also includes assessing the accounting principles used and significant estimates made by management, as well as
evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable
basis for our opinion.
In our opinion, such consolidated financial statements present fairly, in all material respects, the financial
position of Power Integrations, Inc. and subsidiaries at December 31, 2015 and 2014, and the results of their
operations and their cash flows for each of the three years in the period ended December 31, 2015, in conformity
with accounting principles generally accepted in the United States of America. Also, in our opinion, such
consolidated financial statement schedule, when considered in relation to the basic consolidated financial statements
taken as a whole, presents fairly, in all material respects, the information set forth therein.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight
Board (United States), the Company's internal control over financial reporting as of December 31, 2015 based on
the criteria established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring
Organizations of the Treadway Commission, and our report dated February 10, 2016 expressed an unqualified
opinion on the Company’s internal control over financial reporting.

POWER INTEGRATIONS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. THE COMPANY:
Power Integrations, Inc. (“Power Integrations” or the “Company”), incorporated in California on March
25, 1988, and reincorporated in Delaware in December 1997, designs, develops, manufactures and markets analog
and mixed-signal integrated circuits (ICs) and other electronic components and circuitry used in high-voltage
power conversion. The Company’s products are used in power converters that convert electricity from a high-
voltage source (typically 48 volts or higher) to the type of power required for a specified downstream use. A
large percentage of the Company’s products are ICs used in AC-DC power supplies in a wide variety of end
products, primarily in the consumer, communications, computer and industrial markets. The Company acquired
CT-Concept Technologie AG (Concept) in May 2012, and since then offers IGBT drivers used to operate arrays
of high-voltage, high-power transistors known as IGBT modules, which are used for power conversion in high-
power applications such as industrial motors, solar- and wind-power systems, electric vehicles and high-voltage
DC transmission systems.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
Principles of Consolidation
The consolidated financial statements include the accounts of the Company and its wholly owned
subsidiaries after elimination of all intercompany transactions and balances.
Estimates
The preparation of financial statements in conformity with U.S. GAAP requires management to make
estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent
assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company
evaluates its estimates, including those related to revenue recognition and allowances for receivables and
inventories. These estimates are based on historical facts and various other factors, which the Company believes
to be reasonable at the time the estimates are made. However, as the effects of future events cannot be determined
with precision, actual results could differ significantly from management’s estimates.
Cash and Cash Equivalents
The Company considers cash invested in highly liquid financial instruments with maturities of three
months or less at the date of purchase to be cash equivalents.
Marketable Securities
The Company generally holds securities until maturity; however, they may be sold under certain
circumstances including, but not limited to, when necessary for the funding of acquisitions and other strategic
investments. As a result the Company classifies its investment portfolio as available-for-sale. The Company
classifies all investments with a maturity date greater than three months at the date of purchase as short-term
marketable securities in its Consolidated Balance Sheet. As of December 31, 2015, and December 31, 2014, the
Company’s marketable securities consisted primarily of corporate bonds and other high-quality commercial
securities. The weighted average interest rate of investments at December 31, 2015 and December 31, 2014, was
approximately 0.84% and 0.76%, respectively.

POWER INTEGRATIONS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Business Combinations
The purchase price of an acquisition is allocated to the underlying assets acquired and liabilities assumed
based upon their estimated fair values at the date of acquisition. To the extent the purchase price exceeds the fair
value of the net identifiable tangible and intangible assets acquired and liabilities assumed, such excess is allocated
to goodwill. The Company determines the estimated fair values after review and consideration of relevant
information, including discounted cash flows, quoted market prices and estimates made by management. The
Company adjusts the preliminary purchase price allocation, as necessary, during the measurement period of up to
one year after the acquisition closing date as it obtains more information as to facts and circumstances existing at
the acquisition date impacting asset valuations and liabilities assumed. Acquisition-related costs are recognized
separately from the acquisition and are expensed as incurred.
Goodwill and Intangible Assets
Goodwill and the Company's domain name are evaluated in accordance with ASC 350-10, Goodwill and
Other Intangible Assets, and an impairment analysis is conducted on an annual basis, or sooner if indicators exist
for a potential impairment.
In accordance with ASC 360-10, Accounting for the Impairment or Disposal of Long-Lived Assets, long-
lived assets, such as property and equipment and intangible assets, are reviewed for impairment whenever events
or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability
of assets to be held and used is measured by a comparison of the carrying amount of an asset to estimated
undiscounted future cash flows expected to be generated by the asset. If the carrying amount of an asset exceeds
its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount
of the asset exceeds the fair value of the asset.
Employee Benefits Plan
The Company sponsors a 401(k) tax-deferred savings plan for all employees in the United States who
meet certain eligibility requirements. Participants may contribute up to the amount allowable as a deduction for
federal income tax purposes. The Company is not required to contribute; however, the Company contributes a
certain percentage of employee annual salaries on a discretionary basis, not to exceed an established threshold. In
each of 2015, 2014 and 2013, the Company provided for a contribution of approximately $1.1 million.
Retirement Benefit Obligations (Pension)
The Company recognizes the over-funded or under-funded status of a defined benefit pension or post-
retirement plan as an asset or liability in the accompanying consolidated balance sheets. Actuarial gains and losses
are recorded in accumulated other comprehensive income (loss), a component of stockholders’ equity, and are
amortized as a component of net periodic cost over the remaining estimated service period of participants.
Revenue Recognition
Product revenues consist of sales to original equipment manufacturers (OEMs), merchant power supply
manufacturers and distributors. Approximately 75% of the Company’s net product sales were made to distributors
in 2015. The Company applies the provisions of ASC 605-10, Revenue Recognition, and all related appropriate
guidance. Revenue is recognized when all of the following criteria have been met: (1) persuasive evidence of an
arrangement exists, (2) delivery has occurred, (3) the price is fixed or determinable, and (4) collectability is
reasonably assured. Customer purchase orders are generally used to determine the existence of an arrangement.
56
POWER INTEGRATIONS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Delivery is considered to have occurred when title and risk of loss have transferred to the Company’s customer.
The Company evaluates whether the price is fixed or determinable based on the payment terms associated with
the transaction and whether the sales price is subject to refund or adjustment. With respect to collectability, the
Company performs credit checks for new customers and performs ongoing evaluations of its existing customers’
financial condition and requires letters of credit whenever deemed necessary.
Sales to international OEMs and merchant power supply manufacturers for shipments from the Company’s
facility outside of the United States are pursuant to “EX Works” (EXW) shipping terms, meaning that title to the
product transfers to the customer upon shipment from the Company’s foreign warehouse. Sales to international
OEM customers and merchant power supply manufacturers that are shipped from the Company’s facility in
California are pursuant to “delivered at frontier” (DAF) shipping terms. As such, title to the product passes to the
customer when the shipment reaches the destination country and revenue is recognized upon the arrival of the
product in that country. Shipments to OEMs and merchant power supply manufacturers in the Americas are pursuant
to “free on board” (FOB) point of origin shipping terms meaning that title is passed to the customer upon shipment.
Revenue is recognized upon title transfer for sales to OEMs and merchant power supply manufacturers, assuming
all other criteria for revenue recognition are met.
Sales to most of the Company's distributors are made under terms allowing certain price adjustments and
rights of return on the Company's products held by its distributors. As a result of these rights, the Company defers
the recognition of revenue and the costs of revenues derived from these sales until the Company's distributors
report that they have sold the Company's products to their customers. The Company's recognition of such distributor
revenue is based on point of sale reports received from the distributors, at which time the price is no longer subject
to adjustment and is fixed, and the products are no longer subject to return to the Company except pursuant to
warranty terms. The gross profit that is deferred as a result of this policy is reflected as “deferred income on sales
to distributors” in the accompanying consolidated balance sheets. The total deferred revenue as of December 31,
2015, and December 31, 2014, was approximately $25.7 million and $25.0 million, respectively. The total deferred
cost as of December 31, 2015, and December 31, 2014, was approximately $10.6 million and $9.8 million,
respectively.
Frequently, distributors need to sell at a price lower than the standard distribution price in order to win
business. At or soon after the distributor invoices its customer, the distributor submits a “ship and debit” price
adjustment claim to the Company to adjust the distributor's cost from the standard price to the pre-approved lower
price. After verification by the Company, a credit memo is issued to the distributor for the ship and debit claim.
The Company maintains a reserve for unprocessed claims and future ship and debit price adjustments. The reserves
appear as a reduction to accounts receivable and deferred income on sales to distributors in the Company's
accompanying consolidated balance sheets. To the extent future ship and debit claims significantly exceed amounts
estimated, there could be a material impact on the deferred revenue and deferred margin ultimately recognized.
To evaluate the adequacy of its reserves, the Company analyzes historical ship and debit payments and levels of
inventory in the distributor channels.
Sales to certain distributors of the Company are made under terms that do not include rights of return or
price concessions after the product is shipped to the distributor. Accordingly, product revenue is recognized upon
shipment and title transfer assuming all other revenue recognition criteria are met.
Foreign Currency Risk and Foreign Currency Translation
As of December 31, 2015, the Company’s primary transactional currency was U.S. dollars; in addition,
the Company holds cash in Swiss francs and Euros to fund the operations of the Company’s Swiss subsidiary. The

foreign exchange rate fluctuation between the U.S. dollar versus the Swiss franc and Euro is recorded in other
income in the consolidated statements of income.
Gains and losses arising from the re-measurement of non-functional currency balances are recorded in
''other income'' in the accompanying consolidated statements of income. For the years ended December 31, 2015,
2014 and 2013 the Company realized foreign exchange transaction gains (losses) of $(0.5) million, $0.1 million
and $(0.1) million, respectively.
The functional currencies of the Company’s other subsidiaries are the local currencies. Accordingly, all
assets and liabilities are translated into U.S. dollars at the current exchange rates as of the applicable balance sheet
date. Revenues and expenses are translated at the average exchange rate prevailing during the period. Cumulative
gains and losses from the translation of the foreign subsidiaries’ financial statements have been included in
stockholders’ equity.
Warranty
The Company generally warrants that its products will substantially conform to the published
specifications for 12 months from the date of shipment. The Company’s liability is limited to either a credit equal
to the purchase price or replacement of the defective part. Returns under warranty have historically been immaterial,
and as a result, the Company does not record a specific warranty reserve.
Advertising
Advertising costs are expensed as incurred. Advertising costs amounted to $1.1 million, $1.5 million, and
$1.4 million, in 2015, 2014 and 2013, respectively.
Research and Development
Research and development costs are expensed as incurred.
Income Taxes
Income tax expense is an estimate of current income taxes payable or refundable in the current fiscal year
based on reported income before income taxes. Deferred income taxes reflect the effect of temporary differences
and carry-forwards that are recognized for financial reporting and income tax purposes.
The Company accounts for income taxes under the provisions of ASC 740, Income Taxes. Under the
provisions of ASC 740, deferred tax assets and liabilities are recognized based on the differences between the
financial statement carrying amounts of existing assets and liabilities and their respective tax bases, utilizing the
tax rates that are expected to apply to taxable income in the years in which those temporary differences are expected
to be recovered or settled. The Company recognizes valuation allowances to reduce any deferred tax assets to the
amount that it estimates will more likely than not be realized based on available evidence and management’s
judgment. The Company limits the deferred tax assets recognized related to certain officers’ compensation to
amounts that it estimates will be deductible in future periods based upon Internal Revenue Code Section 162(m).
In the event that the Company determines, based on available evidence and management judgment, that all or part
of the net deferred tax assets will not be realized in the future, it would record a valuation allowance in the period
the determination is made. In addition, the calculation of tax liabilities involves significant judgment in estimating
the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner

inconsistent with the Company’s expectations could have a material impact on the Company’s results of operations
and financial position.
The Company engages in qualifying activities for R&D credit purposes. On December 18, 2015, the
Protecting Americans From Tax Hikes Act of 2015 was signed into law, permanently extending the federal R&D
credit.
During 2014, the Company settled with the IRS and closed out the examination of its income tax returns
for the years 2007 through 2009. The resolution of the audit resulted in a federal tax benefit to the Company of
$2.8 million; the Company also recorded a state tax benefit of approximately $0.5 million. The agreement with
IRS also allowed the Company to repatriate $5.0 million from its foreign subsidiary without incurring additional
U.S. income taxes.
Common Stock Repurchases and Common Stock Dividend
In October 2012, the Company’s board of directors authorized the use of $50.0 million for the repurchase
of the Company’s common stock. In 2014 and 2015, the Company’s board of directors authorized the use of an
additional $75.0 million and $60.0 million, respectively, for repurchase of the Company’s common stock, with
repurchases to be executed according to pre-defined price/volume guidelines. No Shares were repurchased during
the year ended December 31, 2013, as the stock price levels exceeded the pre-defined price guidelines mentioned
above. In 2014, the Company purchased 1.6 million shares for approximately $80.8 million. In 2015, the Company
purchased 1.3 million shares for $53.7 million. As of December 31, 2015, the Company had $30.0 million available
for future stock repurchases. Authorization of future stock repurchase programs is at the discretion of the board of
directors and will depend on the Company's financial condition, results of operations, capital requirements, business
conditions as well as other factors.

periods indicated:

The Company paid a total of approximately $13.9 million, $13.2 million and $9.4 million in cash dividends
during 2015, 2014 and 2013, respectively.
In January 2016, the Company’s board of directors declared a $0.13 quarterly dividend for each quarter
in 2016. The declaration of any future cash dividend is at the discretion of the board of directors and will depend
on the Company’s financial condition, results of operations, capital requirements, business conditions and other
factors, as well as a determination that cash dividends are in the best interest of the Company’s stockholders.
Indemnifications
The Company sells products to its distributors under contracts, collectively referred to as Distributor Sales
Agreements (DSA). Each DSA contains the relevant terms of the contractual arrangement with the distributor, and
59
POWER INTEGRATIONS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
generally includes certain provisions for indemnifying the distributor against losses, expenses, and liabilities from
damages that may be awarded against the distributor in the event the Company’s products are found to infringe
upon a patent, copyright, trademark, or other proprietary right of a third party (Customer Indemnification). The
DSA generally limits the scope of and remedies for the Customer Indemnification obligations in a variety of
industry-standard respects, including, but not limited to, limitations based on time and geography, and a right to
replace an infringing product. The Company also, from time to time, has granted a specific indemnification right
to individual customers.
The Company believes its internal development processes and other policies and practices limit its
exposure related to such indemnifications. In addition, the Company requires its employees to sign a proprietary
information and inventions agreement, which assigns the rights to its employees' development work to the Company.
To date, the Company has not had to reimburse any of its distributors or customers for any losses related to these
indemnifications and no material claims were outstanding as of December 31, 2015. For several reasons, including
the lack of prior indemnification claims and the lack of a monetary liability limit for certain infringement cases,
the Company cannot determine the maximum amount of potential future payments, if any, related to such
indemnifications.
Recently Issued Accounting Pronouncements
In May 2014, the FASB amended the existing accounting standards for revenue recognition, ASU 2014-09,
Revenue from Contracts with Customers. The amendments are based on the principle that revenue should be
recognized to depict the transfer of promised goods or services to customers in an amount that reflects the
consideration to which the entity expects to be entitled in exchange for those goods or services. The Company is
required to adopt the amendments in the first quarter of 2018. Early adoption is permitted; however, the Company
is not permitted to adopt the standard earlier than January 1, 2017. The amendments may be applied retrospectively
to each prior period presented or retrospectively with the cumulative effect recognized as of the date of initial
application. The Company is currently evaluating the impact of these amendments and the transition alternatives
on its consolidated financial statements.
In July 2015, the FASB amended the existing accounting standards for the measurement of inventory,
ASU 2015-11, Inventory. The amendments require inventory to be measured at the lower of cost and net realizable
value. Net realizable value is the estimated selling prices in the ordinary course of business, less reasonably
predictable costs of completion, disposal, and transportation. The Company is required to adopt the amendments
in the first quarter of 2017. The amendments should be applied prospectively with early adoption permitted as of
the beginning of an interim or annual reporting period. The Company does not expect that the adoption of these
amendments will have a material impact on its consolidated financial statements.
In November 2015, the FASB issued new guidance on the classification of deferred tax assets and liabilities,
ASU 2015-17, Balance Sheet Classification of Deferred Taxes. The new guidance requires that all deferred tax
assets and liabilities, along with any related valuation allowance, be classified as non-current on the balance sheet.
The Company early adopted the new guidance as of the beginning of the year ended December 31, 2015 and have
applied the amendments on a prospective basis. All deferred tax assets and liabilities as of December 31, 2015,
have been classified as non-current in the Consolidated Balance Sheets and the Notes to Consolidated Financial
Statements in this Form 10-K. The adoption as of the beginning of the year resulted in a $2.2 million decrease to
deferred tax liabilities, a $1.3 million decrease to non-current deferred assets and $0.9 million increase to non-
current tax liabilities. No prior periods were retrospectively adjusted.

3. STOCK PLANS AND SHARE BASED COMPENSATION:
Stock Plans
As of December 31, 2015, the Company had two stock-based compensation plans (the “Plans”) which
are described below.
2007 Equity Incentive Plan
The 2007 Equity Incentive Plan (2007 Plan) was adopted by the board of directors on September 10,
2007, and approved by the stockholders on November 7, 2007, as an amendment and restatement of the 1997 Stock
Option Plan (1997 Plan). The 2007 Plan provides for the grant of incentive stock options, non-statutory stock
options, restricted stock awards, restricted stock unit (RSU) awards, stock appreciation rights, performance-based
(PSU) awards, long-term performance based (PRSU) awards and other stock awards to employees, directors and
consultants. As of December 31, 2015, the total maximum remaining number of shares that may be issued under
the 2007 Plan was 4.7 million shares, which includes 0.9 million options issued but not exercised and 1.6 million
awards granted but unvested. As of December 31, 2015, 2.1 million shares of common stock remain available for
future grant under the 2007 Plan. Pursuant to the 2007 Plan, the exercise price for incentive stock options and non-
statutory stock options is generally at least 100% of the fair market value of the underlying shares on the date of
grant. Options generally vest over 48 months measured from the date of grant. Options generally expire no later
than ten years after the date of grant, subject to earlier termination upon an optionee’s cessation of employment
or service.
Beginning January 27, 2009, grants pursuant to the Directors Equity Compensation Program (which was
adopted by the board of directors on January 27, 2009) to non-employee directors have been made primarily under
the 2007 Plan. The Directors Equity Compensation Program provides for grants to outside directors as follows:
effective annually, upon the first trading day of July, each outside director would receive a grant of an equity award
with an aggregate value of $100,000. At each outside director’s election, such award would consist entirely of
RSUs or entirely of stock options. The quantity of options would be calculated by dividing $100,000 by the Black-
Scholes value on the date of grant. The quantity of RSUs issued would be calculated by dividing $100,000 by the
grant date fair value. Further, on the date of election of a new outside director, such new director would receive
such grant as continuing outside directors receive on the first trading day of July; provided, however, that such
grant is prorated for the portion of the year that such new outside director will serve until the next first trading day
of July. The Directors Equity Compensation Program will remain in effect at the discretion of the board of directors
or the compensation committee.
On July 28, 2009, the 2007 Plan was amended generally to prohibit outstanding options or stock
appreciation rights from being canceled in exchange for cash without stockholder approval.
1997 Employee Stock Purchase Plan
Under the 1997 Employee Stock Purchase Plan (Purchase Plan), eligible employees may apply
accumulated payroll deductions, which may not exceed 15% of an employee’s compensation, to the purchase of
shares of the Company’s common stock at periodic intervals. The purchase price of stock under the Purchase Plan
is equal to 85% of the lower of (i) the fair market value of the Company’s common stock on the first day of each
offering period, or (ii) the fair market value of the Company’s common stock on the purchase date (as defined in
the Purchase Plan). Each offering period consists of one purchase period of approximately six months duration.
An aggregate of 3.0 million shares of common stock were reserved for issuance to employees under the Purchase
61
POWER INTEGRATIONS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
Plan. As of December 31, 2015, of the shares reserved for issuance, 2.8 million shares had been purchased and 0.2
million shares were reserved for future issuance under the Purchase Plan.
Shares Reserved
As of December 31, 2015, the Company had approximately 2.4 million shares of common stock reserved
for future grant under all stock plans.
Stock-Based Compensation
The Company applies the provisions of ASC 718-10, Stock Compensation. Under the provisions of ASC
718-10, the Company recognizes the fair value of stock-based compensation in its financial statements over the
requisite service period of the individual grants, which generally equals a four-year vesting period. The Company
uses estimates of volatility, expected term, risk-free interest rate, dividend yield and forfeitures in determining the
fair value of these awards and the amount of compensation expense to recognize. The Company uses the straight-
line method to amortize all stock awards granted over the requisite service period of the award.
The following table summarizes the stock-based compensation expense recognized in accordance with
ASC 718-10 for the years ended December 31, 2015, 2014 and 2013:

million (comprising approximately $1.2 million related to stock options, $0.5 million related to long term
performance-based awards, $11.3 million related to restricted stock units and $1.3 million related to the Company’s
Purchase Plan).
Stock-based compensation expense in the year ended December 31, 2013, was approximately $16.5
million (comprising approximately $2.3 million related to stock options, $3.2 million related to performance-based

The Company did not grant stock options in the years ended December 31, 2015, 2014 and 2013, and
therefore no fair-value assumptions are reported.
The fair value of employees’ stock purchase rights under the Purchase Plan was estimated using the Black-

PSU Awards
Under the performance-based awards program, the Company grants awards in the performance year in
an amount equal to twice the target number of shares to be issued if the maximum performance metrics are met.
The number of shares that are released at the end of the performance year can range from zero to 200% of the
target number depending on the Company’s performance. The performance metrics of this program are annual
targets consisting of a combination of net revenue, non-GAAP operating earnings and strategic goals. Each
performance-based award share granted from the 2007 Plan will reduce the number of shares available for issuance
under the 2007 Plan by two shares.
During the year ended December 31, 2015, the Company issued approximately 89,000 PSUs to employees
and executives. As the net revenue, non-GAAP operating income and strategic goals are considered performance
conditions, expense associated with these awards, net of estimated forfeitures, is recognized over the service period
based on an assessment of the achievement of the performance targets. The fair value of these PSUs is determined
using the fair value of the Company’s common stock on the date of the grant, reduced by the discounted present
value of dividends expected to be declared before the awards vest. If the performance conditions are not achieved,
no compensation cost is recognized and any previously recognized compensation is reversed.
In January 2015, it was determined that the Company had not reached the minimum level of the
established 2014 performance targets (consisting of revenue and non-GAAP operating income). Accordingly, no
shares subject to PSUs granted in connection with the 2014 performance based incentive plan were released to
the Company’s employees and executives in 2015.

There were no PSU awards released in the year ended December 31, 2015 (as the Company did not reach
its performance goals established for the 2014 PSUs). The grant date fair value of PSU awards released, which
were fully vested, in the years ended December 31, 2014 and 2013, was approximately $3.2 million and $2.0
million, respectively.
PRSU Awards (Long-term Performance Based)
In the first quarter of 2014 the Company began granting PRSU awards. The Company's PRSU program
provides for the issuance of PRSUs which will vest based on the Company's performance measured against the
PRSU Plan's established revenue targets. The PRSUs were granted in an amount equal to twice the target number
of shares to be issued if the maximum performance metrics are met. The actual number of shares the recipient
receives is determined at the end of a three-year performance period based on results achieved versus the Company’s
performance goals, and may range from zero to 200% of the target number. The performance goals for PRSUs
granted in fiscal 2014 and 2015 were based on the Company’s annual revenue growth over the respective three-
year performance period. Each PRSU granted from the 2007 Plan will reduce the number of shares available for
issuance under the 2007 Plan by two shares.
Recipients of a PRSU award generally must remain employed by the Company on a continuous basis
through the end of the applicable three-year performance period in order to receive shares subject to that award.
Expenses associated with these awards, net of estimated forfeitures, are recorded throughout the year depending
on the number of shares expected to vest based on progress toward the performance target. The fair value of PRSU
awards is determined using the fair value of the Company’s common stock on the grant date, reduced by the
discounted present value of dividends expected to be declared before the awards vest. If the performance conditions

The Company grants restricted stock units to employees under the 2007 Plan. RSUs granted to employees
typically vest ratably over a four-year period, and are converted into shares of the Company’s common stock upon
vesting on a one-for-one basis subject to the employee’s continued service to the Company over that period. The
fair value of RSUs is determined using the fair value of the Company’s common stock on the date of the grant,
reduced by the discounted present value of dividends expected to be declared before the awards vest. Compensation
expense is recognized on a straight-line basis over the requisite service period of each grant adjusted for estimated
forfeitures. Each RSU award granted from the 2007 plan will reduce the number of shares available for issuance
under the 2007 Plan by two shares.

4. FAIR VALUE MEASUREMENTS:
ASC 820-10, Fair Value Measurements, clarifies that fair value is an exit price, representing the amount
that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market
participants. As such, fair value is a market-based measurement that should be determined based on assumptions
that market participants would use in pricing an asset or liability. As a basis for considering such assumptions,
ASC 820-10 establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as
follows: (Level 1) observable inputs such as quoted prices for identical assets in active markets; (Level 2) inputs
other than the quoted prices in active markets that are observable either directly or indirectly; and (Level 3)
unobservable inputs in which there is little or no market data, which requires the Company to develop its own
assumptions. This hierarchy requires the Company to use observable market data, when available, and to minimize
the use of unobservable inputs when determining fair value.
The Company's cash and investment instruments are classified within Level 1 or Level 2 of the fair-value
hierarchy because they are valued using quoted market prices, broker or dealer quotations, or alternative pricing
sources with reasonable levels of price transparency. The type of instrument valued based on quoted market prices
in active markets primarily includes money market securities. This type of instrument is generally classified within
Level 1 of the fair-value hierarchy. The types of instruments valued based on other observable inputs (Level 2 of
the fair-value hierarchy) include investment-grade corporate bonds and government, state, municipal and provincial
obligations. Such types of investments are valued by using a multi-dimensional relational model, the inputs are
primarily benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark
securities, bids, offers, and reference data including market research publications.

Intangible assets consist primarily of developed technology, acquired licenses, customer relationships,
trade name, domain name, in-process R&D and patent rights, and are reported net of accumulated amortization.
In January 2015, the Company acquired CamSemi, resulting in the addition of the following intangible assets:
developed technology of $6.6 million, which will be amortized over a period of three - seven years; and customer
relationships of $2.4 million, which will be amortized over a period of five years. In August 2015, the Company
purchased a building with existing third-party leases, resulting in the addition of in-place lease intangible assets
of $0.7 million which will be amortized over a period of two years.
The Company amortizes the cost of all intangible assets over the shorter of the estimated useful life or
the term of the developed technology, acquired licenses, customer relationships, trade name, patent rights and in-
place leases, which range from two to twelve years, with the exception of $4.7 million of in-process R&D and
$1.3 million paid to acquire an internet domain name. In-process R&D is assessed for impairment until the
development is completed and products are available for sale, at which time the Company will begin to amortize
the in-process R&D. The Company does not expect the amortization of in-process R&D to begin in 2016. The
Company acquired the rights to the internet domain name www.power.com, which is now the Company’s primary
domain name; the cost to acquire the domain name has been recorded as an intangible asset and will not be amortized
as it has an indefinite useful life. Amortization of acquired intangible assets was approximately $7.0 million, $6.1
million and $7.4 million in the years ended December 31, 2015, 2014 and 2013, respectively. The Company does
not believe there is any significant residual value associated with the following intangible assets:

Concentration of Credit Risk
Financial instruments that potentially subject the Company to concentrations of credit risk consisted
principally of cash investments and trade receivables. The Company has cash investment policies that limit cash
investments to low-risk investments. With respect to trade receivables, the Company performs ongoing evaluations
of its customers' financial conditions and requires letters of credit whenever deemed necessary. Additionally, the
Company establishes an allowance for doubtful accounts based upon factors surrounding the credit risk of specific
customers, historical trends related to past write-offs and other relevant information. Account balances are charged
off against the allowance after all means of collection have been exhausted and the potential for recovery is
considered remote. The Company does not have any off-balance-sheet credit exposure related to its customers.
Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of
cash investments and trade receivables. As of December 31, 2015, and December 31, 2014, 66% of accounts
receivable were concentrated with the Company’s top 10 customers.
The following customers each represented 10% or more of accounts receivable:

7. EARNINGS PER SHARE:
Basic earnings per share are calculated by dividing net income by the weighted-average shares of common
stock outstanding during the period. Diluted earnings per share are calculated by dividing net income by the
weighted-average shares of common stock and dilutive common equivalent shares outstanding during the period.
Dilutive common equivalent shares included in this calculation consist of dilutive shares issuable upon the assumed
exercise of outstanding common stock options, the assumed vesting of outstanding restricted stock units and
performance based awards, and the assumed issuance of awards under the stock purchase plan, as computed using
the treasury stock method.

(1) The Company includes the shares underlying performance-based awards in the calculation of diluted earnings
per share if the performance conditions have been satisfied as of the end of the reporting period and excludes
such shares when the necessary conditions have not been met. The Company has excluded all performance-
based awards in the 2014 calculation as the performance conditions for those awards were not met as of the end
of the period. The Company has included in the 2015 and 2013 calculations those shares that were contingently
issuable upon the satisfaction of the performance conditions as of the end of the respective periods.
In the years ended December 31, 2015, 2014 and 2013, approximately 8,000, 37,000 and 122,000
outstanding stock awards were determined to be anti-dilutive, respectively, and therefore were excluded from the
computation of diluted earnings per share.
8. PROVISION FOR INCOME TAXES:
Income Taxes
The Company accounts for income taxes under the provisions of ASC 740, Income Taxes. Under the
provisions of ASC 740, deferred tax assets and liabilities are recognized based on the differences between the
financial statement carrying amounts of existing assets and liabilities and their respective tax bases, utilizing the
tax rates that are expected to apply to taxable income in the years in which those temporary differences are expected
to be recovered or settled.

The Company is entitled to a deduction for federal and state tax purposes with respect to employees' stock
option activity. The net reduction in taxes otherwise payable in excess of any amount credited to income tax expense
has been reflected as an adjustment to additional paid-in capital. For 2015, 2014 and 2013, the benefit (deficiency)
arising from employee stock option activity that resulted in an adjustment to additional paid in capital was
approximately $(0.2) million, $0.8 million and $1.3 million, respectively.
The provision for (benefit from) income taxes differs from the amount, which would result by applying
the applicable federal income-tax rate to income before provision for (benefit from) income taxes, as follows:

The effective tax rate for the year ended December 31, 2015 was favorably impacted by the geographic
distribution of the Company’s world-wide earnings in lower-tax jurisdictions. Additionally, the rate was
favorably impacted by the federal R&D tax credit which was extended permanently when the Protecting
Americans From Tax Hikes Act was signed into law on December 18, 2015.
The Company reached a settlement with the IRS in the quarter ended June 30, 2014, to close out the
examination of its federal income-tax returns for the years 2007 through 2009. As a result, the Company adjusted
its tax balances and the provision for income tax for the year ended December 31, 2014, includes a one-time benefit
of $3.3 million comprising $2.8 million in federal income taxes and interest, and state income taxes of approximately
$0.5 million. The one-time benefit includes the reversal of $4.1 million of related unrecognized tax benefits that
had been recorded as non-current liabilities in the Company’s consolidated balance sheets. The Company has now
concluded all U.S. federal income-tax matters for the years through 2009.
The effective tax rate for the year ended December 31, 2013, was favorably impacted by the geographic
distribution of the Company's world-wide earnings and earnings in lower-tax jurisdictions. Additionally, the rate
was favorably impacted by federal research tax credits both for 2013 and 2012.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than
not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax
assets is dependent upon the generation of future taxable income during the periods in which those temporary
differences become deductible. Management considers the scheduled reversal of deferred tax liabilities and
projected future taxable income. In the event that the Company determines, based on available evidence and
management judgment, that all or part of the net deferred tax assets will not be realized in the future, the Company
would record a valuation allowance in the period the determination is made. In addition, the calculation of tax
liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax
laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a
material impact on its results of operations and financial position.

As of December 31, 2015, the Company continues to maintain a valuation allowance primarily as a result
of capital losses for federal purposes, and on its California deferred tax assets as the Company believes that it is
not more likely than not that the deferred tax assets will be fully realized. In addition, the Company maintains a
valuation allowance with respect to certain of its deferred tax assets relating to tax credits in Canada and the state
of New Jersey.
As of December 31, 2015, the Company had federal research and development tax credit carry-forwards
of approximately $12.7 million, which will begin to expire in 2030 if unutilized; federal net operating losses of
$25.1 million, which will begin to expire in 2024 if unutilized; California research and development tax credit
carry-forwards of approximately $16.6 million (there is no expiration of research and development tax credit carry-
forwards for the state of California) and California net operating losses of $50.3 million which will begin to expire
in 2032. As of December 31, 2015, the Company had Canadian scientific research and experimental development
tax credit carry-forwards of approximately $1.9 million and New Jersey research and experimental development
tax credit carry-forwards of approximately $0.6 million, which will start to expire in 2026 and 2027, respectively.
The Company does not provide for U.S. taxes on its undistributed earnings of foreign subsidiaries that it
intends to invest indefinitely outside the U.S., unless such taxes are otherwise required under U.S. tax law. Beginning
in 2013, the Company determined that a portion of its foreign subsidiaries current and future earnings may be
remitted prospectively to the U.S. for domestic cash flow purposes and, accordingly, provided for the related U.S.
taxes in its consolidated financial statements. If the Company changes its intent to invest its undistributed foreign
earnings indefinitely or if a greater amount of undistributed earnings are needed for U.S. operations than previously
anticipated and for which U.S. taxes have not been recorded, the Company would be required to accrue or pay
U.S. taxes (subject to an adjustment for foreign tax credits, where applicable) and withholding taxes payable to
various foreign countries on some or all of these undistributed earnings. As of December 31, 2015, the Company
had undistributed earnings of foreign subsidiaries that are indefinitely invested outside of the U.S. of approximately
$222.0 million. It is not practicable to determine the income tax liability that might be incurred if these earnings
were to be distributed.

The Company's total unrecognized tax benefits as of December 31, 2015, 2014 and 2013, was $13.6
million, $11.2 million and $12.7 million, respectively. An income-tax benefit of $5.6 million, net of valuation
allowance adjustments, would be recorded if these unrecognized tax benefits are recognized. The Company cannot
reasonably estimate the amount of the unrecognized tax benefit that could be adjusted in the next twelve months.
The Company’s continuing practice is to recognize interest and/or penalties related to income-tax matters
in income-tax expense. The Company has accrued interest and penalties at December 31, 2015, and December 31,
2014, of $0.1 million and $0.1 million, respectively, which have been recorded in long-term income taxes payable
in the accompanying Consolidated Balance Sheets.
In July 2013, the FASB issued a new accounting standard that requires the presentation of certain
unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the Company’s consolidated
balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The
Company adopted this new standard on a prospective basis in the first quarter of 2014. The impact of the adoption
was a reduction to long-term deferred tax assets and non-current income tax payable of approximately $4.3 million.
As of December 31, 2015, the Company has concluded all U.S. federal income tax matters for the years
through 2009, and has finalized Swiss income tax returns for the years through 2012. There is currently no pending
income tax audit.
On July 27, 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion related to the
treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. A final decision has
yet to be issued by the Tax Court due to other outstanding issues related to the case. At this time, the U.S. Department

of the Treasury has not withdrawn the requirement to include stock-based compensation expense from IRS cost-
sharing regulations. The Company has reviewed this case and its impact and concluded that no adjustment to the
consolidated financial statements is appropriate at this time. The Company will continue to monitor ongoing
developments and potential impacts to the consolidated financial statements.

10. LEGAL PROCEEDINGS AND CONTINGENCIES:
From time to time in the ordinary course of business, the Company becomes involved in lawsuits, or
customers and distributors may make claims against the Company. In accordance with ASC 450-10, Contingencies,
the Company makes a provision for a liability when it is both probable that a liability has been incurred and the
amount of the loss can be reasonably estimated.
On October 20, 2004, the Company filed a complaint against Fairchild Semiconductor International, Inc.
and Fairchild Semiconductor Corporation (referred to collectively as “Fairchild”) in the United States District
Court for the District of Delaware. In its complaint, the Company alleged that Fairchild has and is infringing four
of Power Integrations’ patents pertaining to pulse width modulation (PWM) integrated circuit devices. Fairchild
77
POWER INTEGRATIONS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
denied infringement and asked for a declaration from the court that it does not infringe any Power Integrations
patent and that the patents are invalid. The Court issued a claim construction order on March 31, 2006 which was
favorable to the Company. The Court set a first trial on the issues of infringement, willfulness and damages for
October 2, 2006. At the close of the first trial, on October 10, 2006, the jury returned a verdict in favor of the
Company finding all asserted claims of all four patents-in-suit to be willfully infringed by Fairchild and awarding
$34.0 million in damages. Fairchild raised defenses contending that the asserted patents are invalid or unenforceable,
and the Court held a second trial on these issues beginning on September 17, 2007. On September 21, 2007, the
jury returned a verdict in the Company’s favor, affirming the validity of the asserted claims of all four patents-in-
suit. Fairchild submitted further materials on the issue of enforceability along with various other post-trial motions,
and the Company filed post-trial motions seeking a permanent injunction and increased damages and attorneys’
fees, among other things. On September 24, 2008, the Court denied Fairchild’s motion regarding enforceability
and ruled that all four patents are enforceable. On December 12, 2008, the Court ruled on the remaining post-trial
motions, including granting a permanent injunction, reducing the damages award to $6.1 million, granting Fairchild
a new trial on the issue of willful infringement in view of an intervening change in the law, and denying the
Company’s motion for increased damages and attorneys’ fees with leave to renew the motion after the resolution
of the issue of willful infringement. On December 22, 2008, at Fairchild’s request, the Court temporarily stayed
the permanent injunction for 90 days. On January 12, 2009, Fairchild filed a notice of appeal challenging the
Court’s refusal to enter a more permanent stay of the injunction, and Fairchild filed additional motions requesting
that both the Federal Circuit and the District Court extend the stay of injunction. The District Court temporarily
extended the stay pending the Federal Circuit ruling on Fairchild’s pending motion, but the Federal Circuit dismissed
Fairchild’s appeal and denied its motion on May 5, 2009, and the District Court issued an order on May 13, 2009
confirming the reinstatement of the permanent injunction as originally entered in December 2008. On June 22,
2009, the Court held a brief bench re-trial on the issue of willful infringement. On July 22, 2010, the Court found
that Fairchild willfully infringed all four of the asserted patents, and the Court also invited briefing on enhanced
damages and attorneys’ fees. Fairchild also filed a motion requesting that the Court amend its findings regarding
willfulness. On January 18, 2011, the Court denied Fairchild’s request to amend the findings regarding Fairchild’s
willful infringement and doubled the damages award against Fairchild but declined to award attorneys’ fees. On
February 3, 2011, the Court entered final judgment in favor of the Company for a total damages award of $12.9
million. Fairchild filed a notice of appeal challenging the final judgment and a number of the underlying rulings,
and the Company filed a cross-appeal seeking to increase the damages award. The appeal was argued on January
11, 2012, and the Federal Circuit issued a mixed ruling on March 26, 2013, affirming Fairchild’s infringement of
certain claims that support the basis for the permanent injunction while reversing, vacating, and remanding the
findings with respect to other claims, including the Company’s claim for damages. The Company filed a petition
seeking Supreme Court review of the Federal Circuit’s ruling on damages issues, and the Supreme Court called
for a response from Fairchild but ultimately declined to review the case. On remand, the Company intends to pursue
its claim for financial compensation based on Fairchild’s infringement.
On May 9, 2005, the Company filed a Complaint with the U.S. International Trade Commission (ITC)
under section 337 of the Tariff Act of 1930, as amended, 19 U.S.C. Section 1337 against System General (SG).
The Company filed a supplement to the complaint on May 24, 2005. The Company alleged infringement of its
patents pertaining to PWM integrated circuit devices produced by SG, which are used in power conversion
applications such as power supplies for computer monitors. The Commission instituted an investigation on June 8,
2005 in response to the Company’s complaint. SG filed a response to the ITC complaint asserting that the patents-
in-suit were invalid and not infringed. The Company subsequently and voluntarily narrowed the number of patents
and claims in suit, which proceeded to a hearing. The hearing on the investigation was held before the Administrative
Law Judge (ALJ) from January 18 to January 24, 2006. Post-hearing briefs were submitted and briefing concluded
February 24, 2006. The ALJ’s initial determination was issued on May 15, 2006. The ALJ found all remaining
asserted claims valid and infringed, and recommended the exclusion of the infringing products as well as certain
downstream products that contain the infringing products. After further briefing, on June 30, 2006, the Commission
78
POWER INTEGRATIONS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
decided not to review the initial determination on liability, but did invite briefs on remedy, bonding and the public
interest. On August 11, 2006, the Commission issued an order excluding from entry into the United States the
infringing SG PWM chips, and any liquid-crystal-display (LCD) computer monitors, AC printer adapters and
sample/demonstration circuit boards containing an infringing SG chip. The U.S. Customs Service is authorized to
enforce the exclusion order. On October 11, 2006, the presidential review period expired without any action from
the President, and the ITC exclusion order is now in full effect. SG appealed the ITC decision, and on November 19,
2007, the Federal Circuit affirmed the ITC’s findings in all respects. On October 27, 2008, SG filed a petition to
modify the exclusion order in view of a recent Federal Circuit opinion in an unrelated case, and the Company
responded to oppose any modification, but the Commission modified the exclusion order on February 27, 2009.
Nevertheless, the exclusion order still prohibits SG and related entities from importing the infringing SG chips
and any LCD computer monitors, AC printer adapters, and sample/demonstration circuit boards containing an
infringing SG chip.
On May 23, 2008, the Company filed a complaint against Fairchild Semiconductor International, Inc.,
Fairchild Semiconductor Corporation, and Fairchild’s wholly owned subsidiary System General Corporation
(referred to collectively as “Fairchild”), in the United States District Court for the District of Delaware. In its
complaint, the Company alleged that Fairchild has infringed and is infringing three patents pertaining to power
supply controller integrated circuit devices. Fairchild answered the Company’s complaint on November 7, 2008,
denying infringement and asking for a declaration from the Court that it does not infringe any Power Integrations
patent and that the patents are invalid and unenforceable. Fairchild’s answer also included counterclaims accusing
the Company of infringing three patents pertaining to primary side power conversion integrated circuit devices.
Fairchild had earlier brought these same claims in a separate suit against the Company, also in Delaware, which
Fairchild dismissed in favor of adding its claims to the Company’s already pending suit against Fairchild. The
Company has answered Fairchild’s counterclaims, denying infringement and asking for a declaration from the
Court that it does not infringe any Fairchild patent and that the Fairchild patents are invalid. Fairchild also filed a
motion to stay the case, but the Court denied that motion on December 19, 2008. On March 5, 2009, Fairchild
filed a motion for summary judgment to preclude any recovery for post-verdict sales of parts found to infringe in
the parties’ other ongoing litigation, described above, and the Company filed its opposition and a cross-motion to
preclude Fairchild from re-litigating the issues of infringement and damages for those same products. On June 26,
2009, the Court held a hearing on the parties’ motions, and on July 9, 2009 the Court issued an order denying the
parties’ motions but staying proceedings with respect to the products that were found to infringe and which are
subject to the injunction in the other Delaware case between the parties pending the entry of final judgment in that
case; those products are expected to be addressed in the context of the parties’ remand proceedings following the
appeal in their earlier litigation in Delaware, and the remainder of the case is proceeding. On December 18, 2009,
the Court issued an order construing certain terms in the asserted claims of the Company’s and Fairchild’s patents
in suit. Following the Court’s ruling on claim construction, Fairchild withdrew its claim related to one of its patents
and significantly reduced the number of claims asserted for the remaining two patents. The parties thereafter filed
and argued a number of motions for summary judgment, and the Court denied the majority of the parties’ motions
but granted the Company’s motion to preclude Fairchild from re-arguing validity positions that were rejected in
the prior case between the parties. Because the assigned Judge retired at the end of July 2010, the case was re-
assigned to a different Judge, and the Court vacated the trial schedule and had the parties provide their input on
the appropriate course of action. The Court thereafter set a trial schedule with the jury trial on infringement and
validity to begin in July 2011. On April 18, 2011, the Court rescheduled the trial to begin in January 2012, and on
June 2, 2011, the Court moved the trial date to April 2012 to permit the parties to address another patent the
Company accused Fairchild of infringing. Following a trial in April 2012, the jury returned a verdict finding that
Fairchild infringes two of the Company’s patents, that Fairchild has induced others to infringe the Company’s
patents, and also upheld the validity of the infringed patents. Of the two remaining counterclaim patents Fairchild
asserted in the case, one was found not to be infringed, but the jury found the second patent to be infringed by a
limited number of the Company’s products, although the jury further found the Company did not induce
79

infringement by any customers, including customers outside the United States. On March 29, 2013, the District
Court denied most of the parties’ post-trial motions on liability but granted the Company’s motion for judgment
as a matter of law finding that Fairchild infringed another of the Company’s patents. On April 25, 2013, the Court
denied both parties’ motions regarding the unenforceability of each other’s patents. The Company is challenging
adverse findings on appeal; nevertheless, the Company estimates that even if the verdict on Fairchild’s patent were
ultimately upheld, the sales potentially impacted would amount to only about 0.3% of the Company’s revenues.
The Company requested an injunction preventing further infringement of its own patents by Fairchild, and Fairchild
requested an injunction as well. Following a hearing on the issue in June 2014, the Court denied Fairchild’s request
for an injunction against the Company and granted the Company’s request for an injunction against Fairchild. On
January 13, 2015, the District Court entered final judgment on the liability and validity issues discussed above,
and both parties filed appeals with the Federal Circuit; briefing and oral argument on the appeal should be completed
in 2016. The Company is also seeking financial damages, as well as enhanced damages for willful infringement,
issues to be decided in separate proceedings at a later date.
On June 28, 2004, the Company filed a complaint for patent infringement in the U.S. District Court,
Northern District of California, against SG Corporation, a Taiwanese company, and its U.S. subsidiary. The
Company’s complaint alleged that certain integrated circuits produced by SG infringed and continue to infringe
certain of its patents. On June 10, 2005, in response to the initiation of the International Trade Commission (ITC)
investigation discussed above, the District Court stayed all proceedings. Subsequent to the completion of the ITC
proceedings, the District Court temporarily lifted the stay and scheduled a case management conference. On
December 6, 2006, SG filed a notice of appeal of the ITC decision as discussed above. In response, and by
agreement of the parties, the District Court vacated the scheduled case management conference and renewed the
stay of proceedings pending the outcome of the Federal Circuit appeal of the ITC determination. On November
19, 2007, the Federal Circuit affirmed the ITC’s findings in all respects, and SG did not file a petition for review.
The parties subsequently filed a motion to dismiss the District Court case without prejudice. On November 4, 2009,
the Company re-filed its complaint for patent infringement against SG and its parent corporations, Fairchild
Semiconductor International, Inc. and Fairchild Semiconductor Corporation, to address their continued
infringement of patents at issue in the original suit that recently emerged from SG requested reexamination
proceedings before the U.S. Patent and Trademark Office (USPTO). The Company seeks, among other things, an
order enjoining SG and Fairchild from infringing the Company’s patents and an award of damages resulting from
the alleged infringement. Fairchild has denied infringement and asked for a declaration from the Court that it does
not infringe any Power Integrations patent, that the patents are invalid, and that one of the two of the Company’s
patents now at issue in the case is unenforceable. On May 5, 2010, SG and Fairchild filed an amended answer
including counterclaims accusing the Company of infringing two patents, and since that time Fairchild has
withdrawn its claim for infringement of one of the patents it originally asserted against the Company but added
another patent to the case over the Company’s objections; the Company contests these claims vigorously. Both
parties filed summary judgment motions and challenges to each other’s experts’ testimony, and the Court granted
the Company’s motion for summary judgment of non-infringement with respect to one of Fairchild’s two patents.
Following a trial on the remaining claims in February 2014, the jury returned a verdict in the Company’s favor,
affirming the validity of the asserted claims of the Company’s patents-in-suit, finding that SG and Fairchild infringed
the Company’s asserted patents and induced infringement by others, and awarding $105.0 million in damages. The
Jury also rejected Fairchild’s remaining counterclaims for infringement against the Company. Fairchild challenged
these rulings in post-trial motions, but the judge confirmed the jury’s determinations on infringement and damages,
although the Court declined to find Fairchild’s infringement willful. Fairchild also pressed its unenforceability
claim with respect to one of the two patents it was found to infringe in post-trial briefing, but the Court rejected
Fairchild’s unenforceability claim. Fairchild also requested reconsideration of the damages determinations, and
the Court granted a new trial with respect to damages but none of the other issues addressed in the previous trial,
with the retrial scheduled for December 2015. Thereafter, the parties completed pretrial proceedings challenging
each other’s experts, and the Court granted portions of each party’s motions limiting the scope of expert testimony
80

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
for purposes of the damages retrial, but neither party was successful in their efforts to prevent the other side’s
experts from testifying at trial. Following a retrial on the issue of damages in December 2015, the jury returned
a verdict in the Company’s favor, finding that the Company’s patented technology created the basis for customer
demand for the infringing Fairchild products and awarding $139.8 million in damages. Although the jury awarded
damages, at this stage of the proceedings the Company cannot state the amount, if any, it might ultimately recover
from Fairchild, and no benefits have been recorded in the Company’s consolidated financial statements as a result
of the damages verdict. The Company has also filed a motion requesting enhanced damages and attorney fees and
intends to request an injunction to prevent further infringement. Fairchild has stated that it intends to challenge
the verdict; briefing on post-trial motions is expected to take place over the coming months.
In February 2010, Fairchild and System General (SG) filed suits for patent infringement against the
Company, Power Integrations Netherlands B.V., and representative offices of Power Integrations Netherlands in
Shanghai and Shenzhen with the Suzhou Intermediate Court in the People’s Republic of China. The suits assert
four Chinese patents and seek an injunction and damages of approximately $19.0 million. Power Integrations
Netherlands filed invalidation proceedings for all four asserted SG patents in the People’s Republic of China Patent
Reexamination Board (PRB) of the State Intellectual Property Office (SIPO), and all four challenges were accepted
by the PRB, with hearings conducted in September 2010. In early January 2012, the Company received rulings
from the PRB invalidating the majority of the claims Fairchild asserted in litigation. The Suzhou Court conducted
evidentiary hearings in 2012 and issued rulings in late December 2012, finding that the Company did not infringe
any of the asserted patents. Fairchild filed appeals challenging the Suzhou Court’s non-infringement rulings, and
the appeals court in Nanjing held further hearings in the infringement proceedings in late 2014, but Fairchild has
since dismissed its appeals, bringing the infringement proceedings to a close in the first quarter of 2015.
On July 11, 2011, the Company filed a complaint in the U.S. District Court, District of Columbia, against
David Kappos in his capacity as Director of the United States Patent and Trademark Office (PTO) as part of the
ongoing reexamination proceedings related to one of the patents asserted against Fairchild and SG in the Delaware
litigation described above. The Company filed a motion for summary judgment on a preliminary jurisdictional
issue, and the PTO filed a cross-motion to dismiss on this same issue; briefing on those motions was completed
in October, 2011. On November 18, 2013, the Court granted the PTO’s motion and transferred the case to the
Federal Circuit, where additional briefing took place. Following a hearing in May 2015, the Federal Circuit ruled
in the Company’s favor on August 12, 2015, overturning the PTO’s claim construction and remanding the case for
further proceedings.
On May 1, 2012, Fairchild Semiconductor Corporation and Fairchild's wholly-owned subsidiary, System
General Corporation (referred to collectively as “Fairchild”), filed a complaint against the Company in the United
States District Court for the District of Delaware. In its complaint, Fairchild alleged that the Company has infringed
and is infringing four patents pertaining to power conversion integrated circuit devices. The Company answered
Fairchild’s complaint, denying infringement and asking for a declaration from the Court that it does not infringe
any Fairchild patent and that the Fairchild patents are invalid, and the Company also asserted counterclaims against
Fairchild for infringement of five of the Company’s patents. Fairchild has withdrawn its claim for infringement
of one of the patents it asserted against the Company after the Company’s preliminary challenge. The parties
streamlined their contentions in view of the Court's pretrial rulings, and following a trial in late May and early
June 2015, a jury returned a verdict finding that Fairchild infringed one of the Company's patents, that Fairchild
has induced and contributed to others' infringement of the Company's patent, and that the Company induced
infringement of a Fairchild patent that was previously found infringed in the 2012 trial described above, with a
damages award of $2.4 million in favor of Fairchild. However, in parallel proceedings the Patent Office has rejected
all of the asserted claims of the one Fairchild patent found infringed, determinations that Fairchild is challenging
on appeal, and the Court rejected Fairchild’s earlier request for an injunction based on those same claims. Both
parties have filed post-trial motions and challenges to various portions of the jury verdicts, and the Court is expected
81
POWER INTEGRATIONS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
to address the first wave of post-trial motions over the coming months. The Company believes it has valid defenses
against the $2.4 million award in favor of Fairchild, and therefore has not recorded a loss in its financial statements
at this time.
On October 21, 2015, the Company filed a complaint for patent infringement against Fairchild
Semiconductor Corporation, Fairchild Semiconductor International, Inc., and wholly-owned subsidiary Fairchild
(Taiwan) Corporation (referred to collectively as “Fairchild”) to address Fairchild’s continued infringement of two
patents Fairchild was previously found to infringe in the three District Court cases the Company brought against
Fairchild discussed above. In each of the three prior cases, Fairchild was found to infringe one of the patents at
issue in the latest complaint, and Fairchild’s challenges to the validity of the patents were rejected during the course
of the prior lawsuits as well. Fairchild has not yet answered the complaint, and no trial date has been scheduled,
but further proceedings are expected over the course of the coming months.
The Company is unable to predict the outcome of legal proceedings with certainty, and there can be no
assurance that Power Integrations will prevail in the above-mentioned unsettled litigations. These litigations,
whether or not determined in Power Integrations' favor or settled, will be costly and will divert the efforts and
attention of the Company's management and technical personnel from normal business operations, potentially
causing a material adverse effect on the business, financial condition and operating results. Currently, the Company
is not able to estimate a loss or a range of loss for the ongoing litigation disclosed above, however adverse
determinations in litigation could result in monetary losses, the loss of proprietary rights, subject the Company to
significant liabilities, require Power Integrations to seek licenses from third parties or prevent the Company from
licensing the technology, any of which could have a material adverse effect on the Company's business, financial
condition and operating results.
11. ACQUISITIONS:
Cambridge Semiconductor Limited
In December 2014, the Company entered into a loan agreement with Cambridge Semiconductor Limited
(CamSemi), a UK company, in which $6.6 million was outstanding as of December 31, 2014. The estimated fair
value of the loan, which was a level 3 fair value measurement approximated the carrying value of $6.6 million, as
the loan was outstanding for less than a month and the interest rate approximated a market rate for such a loan.
The loan was in anticipation of a definitive agreement the Company entered into to acquire CamSemi on January
2, 2015.
On January 2, 2015, the Company acquired 100% of the shares outstanding of CamSemi for total
consideration of approximately $23.3 million, of which $16.7 million was paid in cash and $6.6 million was applied
against the outstanding loan owed to the Company. The acquisition-related costs for the purchase of CamSemi
totaled $1.0 million, with $0.8 million recognized in 2014 and $0.2 million recognized in 2015.
CamSemi was acquired to accelerate the Company's product development efforts for the low-power
market. The acquisition also broadens the Company's technology and product portfolio for low-power applications,
particularly in the mobility and LED lighting markets. The purchase price allocated to goodwill in the acquisition
(as noted in the purchase price allocation below) is related largely to synergies and economies of scale expected
from combining the operations of CamSemi with those of the Company.

The fair value of the identifiable intangible assets: developed technology and customer relationships were
determined based on the following approach.
Developed Technology. The income approach was used to value the acquired developed technology.
Revenue attributable to the Company’s technology was estimated based on expected evolution of the technology
over time. Expenses were assumed to reflect the costs necessary to support the developed technology. The present
value was capitalized as developed technology as of the acquisition date and is being amortized using a straight-
line method to cost of revenues over the estimated life of 3 - 7 years.
Customer Relationships. An intangible customer relationship asset was recognized to the extent that the
Company was expected to benefit from future revenues reasonably anticipated given the historical customer
relationships and operating practices of CamSemi. In order to determine the fair value of the customer relationships,
the Company’s analysis assumed that the Company would immediately benefit from the economics generated by
CamSemi’s existing customer relationships. This amount was reduced by the potential impact given no past
customer relationships and the assumption that the Company could reacquire the customer relationships and ramp
up to a similar level of revenue within two years. The fair value of customer relationships was capitalized as of
the acquisition date and is being amortized on a straight line basis to sales and marketing expenses over the estimated
life of 5 years.
Pro forma results of operations for this acquisition have not been presented because it is not material to
the Company’s consolidated financial statements.

Corporate Headquarters Building
In August 2015, the Company purchased a building adjacent to its corporate headquarters in San Jose,
California to support the continued growth of the business. The purchase has been accounted for using the acquisition
method of accounting in accordance with ASC 805, Business Combinations, as the building had existing rental
income resulting from in-place lease agreements with third-party tenants. The aggregate purchase price of $10.4
million, funded with cash on hand, was allocated as follows: $3.5 million for land, $6.3 million for building and
improvements, $0.7 million for in-place leases and $(0.1) million for liabilities assumed. The building and
improvements are being depreciated on a straight-line basis over an estimated useful life of up to 30 years.
Additionally, as a result of the purchase, the Company acquired existing third-party leases that were valued as in-
place lease intangible assets and are being amortized over the weighted average estimated life of 2 years. The
valuation of the acquired in-place leases were estimated by the Company based on the amount of avoided cash
outflows necessary to originate such leases. Acquisition-related costs in connection with the building purchase
were included in other income, net in the consolidated statements of income and were not material for the periods
presented.
Rental income from third-party leases and the proportionate share of building expenses for those leases
are included in other income, net in the consolidated statements of income from the date of acquisition. These
amounts were not material for the periods presented.
12. RETIREMENT PLANS:
In connection with the Company's acquisition of Concept in May 2012, the Company sponsors a defined
benefit pension plan (Pension Plan) in accordance with the legal requirements of Switzerland. The plan assets,
which provide benefits in the event of an employee’s retirement, death or disability, are held in legally autonomous
trustee-administered funds that are subject to Swiss law. Benefits are based on the employee’s age, years of service
and salary, and the plan is financed by contributions by both the employee and the Company.
The net periodic benefit cost of the Pension Plan was not material to the Company's financial statements
during the years ended December 31, 2015, 2014 and 2013. At December 31, 2015, the projected benefit obligation
was $9.0 million, the plan assets were $6.0 million and the net pension liability was $3.0 million. As of December
31, 2014, the projected benefit obligation was $8.1 million, the plan assets were $5.8 million, and the net pension
liability was $2.3 million. The Company has recorded the unfunded amount as a liability in its Consolidated Balance
Sheet at December 31, 2015 and 2014, under the other liabilities caption. The Company expects to make
contributions to the Pension Plan of approximately $0.4 million during 2016. The unrealized actuarial loss on
pension benefits, net of tax at December 31, 2015, 2014 and 2013 was $1.6 million, $1.2 million and $0.8 million,
respectively. These amounts were reflected in Note 2 above under the caption accumulated other comprehensive
income.
In accordance with the Compensation-Retirement Benefits Topic of ASC 715-20, Defined Benefits Plan,
the Company recognizes the over-funded or under-funded status of its defined post-retirement plan as an asset or
liability in its statement of financial position. The company measured the plan assets and benefit obligations as of
the date of the fiscal year-end.
13. BANK LINE OF CREDIT:
On July 5, 2012, the Company entered into a Credit Agreement with two banks. The Credit Agreement
provides the Company with a $100.0 million revolving line of credit to use for general corporate purposes with a
84
POWER INTEGRATIONS, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)
$20.0 million sublimit for the issuance of standby and trade letters of credit. The Credit Agreement was amended
on April 1, 2014, to extend the Credit Agreement termination date from July 5, 2015, to April 1, 2017, with all
other terms of the Credit Agreement remaining the same. The Company’s ability to borrow under the revolving
line of credit is conditioned upon the Company’s compliance with specified covenants, including reporting and
financial covenants, primarily a minimum cash requirement and a debt to earnings ratio, with which the Company
is currently in compliance. All advances under the revolving line of credit will become due on April 1, 2017, or
earlier in the event of a default. As of December 31, 2015, the Company had no amount outstanding under the
Credit Agreement.
14. SELECTED QUARTERLY INFORMATION (Unaudited):
The following tables set forth certain data from the Company's consolidated statements of income for
each of the quarters in the years ended December 31, 2015 and 2014.
The unaudited quarterly consolidated financial statements have been prepared on the same basis as the
audited consolidated financial statements contained herein and include all adjustments that the Company considers
necessary for a fair presentation of such information when read in conjunction with the Company's annual audited
consolidated financial statements and notes thereto appearing elsewhere in this report. The operating results for
any quarter are not necessarily indicative of the results for any subsequent period or for the entire fiscal year.

Schedule II
Valuation and Qualifying Accounts
The Company maintains an allowance for doubtful accounts for estimated losses resulting from the
inability of customers to make required payments. This allowance is established using estimates formulated by the
Company’s management based upon factors such as the composition of the accounts receivable aging, historical
bad debt, changes in payments patterns, customer creditworthiness, and current economic trends. The Company
maintains an allowance for the distributors’ ship and debit credits relating to the sell-through of the Company’s
products. This reserve is established using the Company’s historical ship and debit amounts and levels of inventory
in the distributor channels.
Following is a summary of the activity in the allowance for doubtful accounts and allowance for ship and
