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
