What Power Integrations does

Power Integrations (NASDAQ: POWI) is a San Jose, California-based semiconductor company founded in 1988 that designs, develops, markets, and manufactures high-voltage analog integrated circuits (ICs) for power conversion. The company's proprietary PowiGaN gallium-nitride technology, which supports device ratings up to 1700V, combined with its SCALE-2 ASIC gate driver platform, forms the technical foundation of a portfolio that addresses power conversion from sub-watt standby supplies up to multi-kilowatt industrial and traction applications. Core product families include InnoSwitch and TOPSwitch for AC-DC conversion, InnoMux for multi-output flyback, LinkSwitch and TinySwitch for low-power off-line switching, BridgeSwitch for BLDC motor drives, Hiper for high-power PFC and LLC stages, Qspeed SiC hybrid diodes, and SCALE-2/SCALE-iFlex gate drivers for IGBT and SiC MOSFET modules.

Power Integrations generates revenue primarily through hardware sales of its ICs to OEMs, ODMs, and contract manufacturers in consumer electronics, industrial equipment, automotive, and data center markets, with 98% of FY2025 net revenue from international customers. Products are sold in high volumes (typically 10,000+ unit quantities) through a hybrid go-to-market combining authorized distributors across the Americas, China, Europe/ME/Africa, India/SE Asia, Japan, Korea, and Taiwan, with direct regional sales offices in San Jose, Shenzhen, Taipei, and Zurich for strategic accounts. Pricing is quote-based and not publicly disclosed for most product lines, with one notable exception: TOPSwitchGaN ICs are publicly priced at $1.00 per unit at 10,000-unit volumes. The company complements its hardware with a free design tool suite (PI Expert), hundreds of downloadable reference designs, MotorXpert motor-drive software, and PowerPros 24/6 technical support to accelerate customer design-in.

FY2025 revenue was $443.5M, up 6% from $419.0M in FY2024, and Q1 2026 revenue was $108.3M (up 3% YoY). The company is publicly listed on NASDAQ, operates with ~$249.5M in cash, and is led by President and CEO Jennifer Lloyd. Recent strategic priorities include co-developing reference designs with NVIDIA for the Kyber 800VDC AI data center architecture, expanding automotive revenue (targeting $100M by 2029 versus a 2026 doubling trajectory), and launching TOPSwitchGaN to push flyback topology into higher-wattage applications previously served by resonant and LLC converters.
