Appliances IconPower Integrations offers a broad range of highly integrated, high-voltage ICs for off-line power conversion in 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.

Unstable and High Mains Voltage

High-quality appliances and other consumer electronic products require higher voltage margins in regions with unstable mains grids, tropical regions with frequent lightning strikes or areas where high-energy ring-waves and surges are prevalent. For example, OEMs addressing the burgeoning market in India for high-quality consumer products without such margins can suffer a continuous stream of electrically damaged and returned products that must be serviced or replaced.

Power Integrations offers a full range of offline switcher ICs incorporating 900 V primary MOSFETs, providing effective and inexpensive protection, a substantial reduction in operating and product-support costs.

  • LinkSwitch-TN2 for low component count buck converters
  • LinkSwitch-XT2 for isolated and non-isolated flybacks up to 8 W
  • InnoSwitch3-EP for high-efficiency isolated flybacks up to 35 W

These highly integrated 900 V devices enable design engineers to realize a truly “one-world” power supply that meets the reliability expectations of users everywhere. They can also replace corresponding 725 V switchers in existing board designs to support higher voltages without altering the designs.
