About Power Integrations
Power Integrations designs high-voltage power conversion chips. Its semiconductors turn wall power into the precise voltages electronics need, and it sells mostly into appliances, phones, and industrial equipment, earning revenue from chip sales to device makers.
Its AI-relevant line targets the data center. InnoSwitch parts serve AI server power supplies, HiperPFS handles power factor correction, GaN AI Power Solutions use gallium nitride for higher efficiency, and Data Center Power ICs round out the portfolio.
Founded in 1988 and headquartered in San Jose, California, Power Integrations trades on the NASDAQ and employs about 880 people under CEO Jennifer A. Lloyd.
Power Integrations in the AI buildout
Power Integrations sits in the Semiconductors layer with an emerging link to AI power delivery. Every AI server needs efficient power conversion, and its newer GaN parts aim at exactly that socket. Today, though, most revenue comes from appliances, phones, and industrial gear, so data center power is a growth option rather than a major contributor. Supercycle scores its AI exposure at 20 out of 100, reflecting potential that has not yet become the core business.
POWI is tracked in Semiconductors, rated Peripheral on the AI Exposure leaderboard.
