Power Integrations (POWI) Launches TOPSwitchGaN IC Family Supporting 440 W Power Range

Power Integrations Inc. (NASDAQ:POWI) is one of the small-cap stocks that are on fire right now. On March 23, Power Integrations introduced the TOPSwitchGaN flyback IC family, a breakthrough that extends the power range of flyback converters to 440 W. This innovation allows engineers to use a much simpler flyback architecture for high-power applications that previously required complex resonant and LLC topologies.

By combining the company’s PowiGaN technology with its established TOPSwitch architecture, the new ICs significantly reduce system cost, complexity, and design time while improving overall manufacturability. The new ICs achieve 92% efficiency across the entire load range and consume less than 50 mW in standby mode, exceeding European Energy-related Products/ErP regulations.

The use of 800 V PowiGaN switches enables low conduction and switching losses, allowing for operation at frequencies up to 150 kHz, which helps minimize transformer size. These benefits make the family ideal for demanding applications such as high-end appliances, industrial power supplies, and e-bike chargers. Power Integrations Inc. (NASDAQ:POWI) offers the TOPSwitchGaN ICs in two distinct packages: the low-profile eSOP-12 for ultra-slim, heat-sink-free designs up to 135 W, and the eSIP-7 for higher power outputs when paired with a simple clip-on heat sink.

Power Integrations Inc. (NASDAQ:POWI) provides analog and mixed-signal semiconductor solutions to original equipment manufacturers and distributors.
