FAN7680 Datasheet Pc Power Supply Outputs Monitoring Ic

Manufacturer: Fairchild (now onsemi)

Overview: www.fairchildsemi.com FAN7680 PC Power Supply Outputs Monitoring.

General Description

The FAN7680 is a complete output supervisory circuitry intended for use in the secondary side of a switched mode power supply.

It provides over voltage protection (OVP), under voltage protection (UVP), fault protection output (FPO), remote On/Off (PSON), latch, internal delay circuits and power good signal generator to monitor and control the output of the switching power supply system.

As for output control, power good output(PGO) and fault protection output(FPO) are included.
