Industrial Controls

Power Integrations offers a broad range of highly integrated, high-voltage ICs for industrial applications. Each IC includes a high voltage power MOSFET combined with control and protection circuitry on a single chip. Features include current limiting and thermal shutdown with automatic fault recovery capability to improve reliability and frequency jittering to reduce EMI.


Design Examples


Auxiliary Power Supplies

Multiple families available to cover non isolated and isolated power supply, optimized to get high efficiency, low component count and full protection features to maximize reliability.

Ultra-Wide Input Voltage Supplies

Applications requiring voltage input above 350V AC are served using 900V rated MOSFET up to 484V input. For higher input voltage (like 580 V) stack-fet topology is preferred. Floating Constant Current Source (described in DI-152), allows the IC to start up and operate at input voltages as low as 18 V.
