Power Supply Supervisor + PWM

General Description

FAN6103 controller is designed for switching mode power supply for desktop PCs. It provides all the functions necessary to monitor and control the output of the power supply. Remote ON/OFF control, power good circuitry, and protection features against over-voltage and over-power are implemented. It directly senses all the output rails for OVP without the need of external dividers. An innovated AC-signal sampling circuitry provides a sufficient power-down warning signal for PG.A built-in timer generates accuracy timing for control circuit, including the PS-off delay. The cycle-by-cycle PWM switching prevents the power transformer from saturation and ensures the fastest response for the short-circuit protection, which greatly reduces the stress for power transistors.     Utilizing minimum external components, the FAN6103 includes all of the functions for push-pull and/or halfbridge topology, decreasing the production cost and PCB space, while increasing the mean time between failures for power supply
