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), undervoltage 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. It directly senses all the output rails for OVP and UVP without external dividers. The FAN7680 offers a simple and cost effective solution with minimum number of external components and greatly reduces PCB board space for power supply.
