## Products & services

Power Integrations’ products include integrated circuits for AC–DC power conversion, LED lighting and brushless DC (BLDC) motor control. Its TOPSwitch, TinySwitch, LinkSwitch and Hiper families serve a range of power levels; its broader IC portfolio supports AC–DC supplies up to about 500 W and some high-voltage DC–DC applications. [2](https://app.finbar.com/go?id=P15619551)[8](https://app.finbar.com/go?id=P213646)[9](https://app.finbar.com/go?id=P29253289)

InnoSwitch integrates primary-side, secondary-side and feedback circuits in one package, using FluxLink control without optical components. Its GaN variants include 900 V and 1,250 V devices; InnoMux supports up to three DC outputs, and InnoMux-2 incorporates 1,700 V GaN transistors. The company’s PowiGaN devices use gallium nitride switches, while EcoSmart, CapZero and SenZero technologies address power-conversion efficiency and standby-power consumption. [10](https://app.finbar.com/go?id=P54630776)[11](https://app.finbar.com/go?id=P99599400)[12](https://app.finbar.com/go?id=P59912959)

For motor control, BridgeSwitch ICs serve BLDC applications up to about 400 W, while BridgeSwitch-2 extends the range to approximately 746 W. Gate-driver products include SCALE and SCALE-2 boards and driver cores, as well as SCALE-iDriver ICs for applications from a few kilowatts to about 100 kW; the wider gate-driver range serves applications from about 100 kW to gigawatts.

## Geographic presence

Power Integrations’ sales are geographically broad: in 2025, 98% of net revenue came from international sales, measured by customer bill-to location, and Asia accounted for approximately 84% of net revenue. The filing does not provide a country-by-country revenue breakdown. [18](https://app.finbar.com/go?id=P107392711) Sales offices are listed in the U.S., U.K., Germany, Italy, India, China, Japan, South Korea, the Philippines, Canada, Singapore and Taiwan; the company also sells through independent representatives and distributors worldwide. [19](https://app.finbar.com/go?id=P94377474)

The company’s principal executive, administrative, manufacturing and technical offices are in San Jose, California. It also owns an R&D facility in New Jersey, a design center in Germany and a multipurpose office building in Switzerland. Leased administrative space includes Singapore, the U.K., the Philippines, New York and Malaysia, in addition to sales offices in other countries. [20](https://app.finbar.com/go?id=P31814361)

Production is substantially outsourced: independent subcontractors assemble, package and test ICs in China, Malaysia, Thailand and the Philippines. Gate-driver boards are assembled and tested by subcontractors in Sri Lanka and Thailand. Some testing is also conducted at company facilities in California and Switzerland. [21](https://app.finbar.com/go?id=P35334379) At year-end 2025, approximately 16% of property and equipment was held by a subcontractor in Malaysia. [22](https://app.finbar.com/go?id=P61397853)
[18](https://app.finbar.com/go?id=P107392711)[19](https://app.finbar.com/go?id=P94377474)[20](https://app.finbar.com/go?id=P31814361)[21](https://app.finbar.com/go?id=P35334379)[22](https://app.finbar.com/go?id=P61397853)

## Business segments

Power Integrations reports one operating and reportable segment: the design, development, manufacture and marketing of integrated circuits and related components used primarily in high-voltage power conversion; it does not report separate operating segments. [23](https://app.finbar.com/go?id=P69980437) Its FY2025 revenue mix by end market—not formal segments—was Industrial 38%, Consumer 37%, Computer 13%, and Communications 12%. [24](https://app.finbar.com/go?id=T1935162) Applying those rounded percentages to FY2025 net revenue of $443.5 million implies approximate contributions of $168.5 million, $164.1 million, $57.7 million, and $53.2 million, respectively; these are estimates, not reported category revenue amounts.

## Company history

Power Integrations was founded in 1988 by Klas Eklund, Art Fury, and Steve Sharp, and incorporated in California on March 25 of that year. Its first commercial product, TOPSwitch, launched in 1994. The company went public on Nasdaq in December 1997 and introduced TinySwitch in 1998, adding its EcoSmart energy-efficiency technology to power-supply ICs.

Balu Balakrishnan became CEO in 2002. In 2012, Power Integrations acquired Swiss company CT-Concept Technologie AG, broadening its business into high-power gate-driver technology. The company added Cambridge Semiconductor’s AC–DC controller business in 2015. [5](https://www.power.com/company) [28](https://investors.power.com/news/news-details/2012/Power-Integrations-Agrees-to-Acquire-CT-Concept-Technologie-AG/default.aspx)

Product and technology milestones included the 2014 launch of InnoSwitch, whose ICs integrate several power-conversion functions, and the introduction of SCALE-iDriver gate-driver ICs in 2016. The company began shipping products using its internally developed PowiGaN technology in 2018. In 2025, Jennifer Lloyd succeeded Balakrishnan as CEO, ending his tenure in that role, which began in 2002.
