SENZero Power Control Switches, Power Integrations
Compact low-cost switch ICs which can be used to eliminate losses in resistive signal paths connected between high-voltage rails and switching power supply controllers. Typical applications include the feed-forward or feedback signal paths in PFC systems and power converters. The devices integrate 650V MOSFET switches with sensing and gate drive circuitry in compact SO-8 packages. Both two and three channel versions are available.
Eliminates significant standby losses in converter resistive signal paths Disconnects unnecessary circuit blocks during standby, remote-off or light-load conditions Ultra low leakage (maximum 1 mA) 650V MOSFETs No external components or additional bias supply needed for remote-off Minimal component count provides higher reliability Protection features to help production/manufacturing yields Energy Efficient: <3 mW loss at 230 Vac in Off/standby mode
