Description

The FAN7685/FAN7686/FAN7687 is a complete output supervisory circuitry intended for use in the secondary side of the switched mode power supply. It provides overvoltage protection (OVP), undervoltage protection(UVP), overcurrent protection (OCP), and power good signal generator to monitor and control the outputs of the switching power supply system.
