Power Integrations SEN013DG, Triple, High Voltage Control Signal Power Switch IC 8-Pin, SOIC

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
