FAN7680 - Fairchild Semiconductor

FAN7680 PC Power Supply Outputs Monitoring IC

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 s.
