Power Integrations pioneered the market for highly integrated power conversion ICs, introducing the industry’s first commercially successful monolithic high-voltage IC family, TOPSwitch™, in 1994. Since then POWI has remained solely focused on the power-conversion market, building a portfolio of products designed to make power converters smaller, simpler, more reliable, easier to design and manufacture, and more energy-efficient.

InnoSwitch™ ICs enable compact, efficient fast-chargers for mobile devices

HiperPFS™ and HiperLCS™ ICs replace up to 100 components in a TV or PC power supply


POWI’s history of innovation is embodied in its extensive patent portfolio, with nearly 700 issued U.S. patents related to the company’s proprietary high-voltage process technology, circuit- and system-design innovations, IC packaging and more.
