Major Appliance Applications
Power Integrations offers a broad range of highly integrated, high-voltage ICs for off-line power conversion in major appliance applications. Each IC includes a 700 V 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, frequency jittering to reduce EMI, and EcoSmart® technology to dramatically reduce standby energy waste.
