电源监控+ PWM Power Supply Supervisor + PWM
DESCRIPTION
The SG6108 controller is designed for desktop PC switching mode power supplies. It provides everything
necessary to monitor and control the output of the power supply. Remote ON/OFF control, power good circuitry, over-voltage protection, over-power protection, and over-current protection are all included. The SG6108 directly senses all the output rails for over voltage conditions without requiring external dividers.
