Power Integrations Inc
A Silicon Valley semiconductor company that makes high-voltage power conversion chips — the integrated circuits that let everything from phone chargers to industrial equipment turn wall electricity into usable power while wasting as little as possible. Founded in 1988 in San Jose, California, by Klas Eklund, Art Fury, and Steve Sharp, the company's name simply describes its work: making power and integrating it into a single chip. Its EcoSmart technology, introduced in 1998 and even demonstrated to President George W. Bush in 2001, drastically cuts the power devices draw while sitting idle — the reason many electronics meet modern standby-energy standards.
