Major Appliances
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.
A complete range of offline switcher ICs with 900 V primary MOSFETs are available for high-quality appliances destined for regions with unstable mains grids, tropical regions with frequent lightning strikes or any area where high-energy ring-waves and surges are prevalent.
