Key Pillars

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.

POWI’s EcoSmart™ technology, which drastically reduces standby power consumption in electronic products and appliances, has eliminated billions of dollars’ worth of energy waste in electronic products since 1998, preventing millions of tons of carbon emissions. LYTSwitch™ ICs power energy-saving LED lights, while BridgeSwitch™ motor-driver ICs improve the efficiency of appliances that use brushless DC motors. SCALE™ gate drivers are critical components in clean technologies such as solar and wind power, electric vehicles and more.

The company's stock is included in numerous clean-technology indexes including The Cleantech Index and Nasdaq Clean Edge Green Energy Index.
