DESCRIPTION

The SC6105 is a switching mode power supply controller for computers. It can regulator the output voltages by providing PWM signals to drive a transformer. It monitors and protects the 3.3V/±5V/±12V outputs. Two internal TL431 shunt regulators provide stable reference voltage for 3.3V and 5V-standby regulator. Remote ON/OFF control, power good circuitry, over voltage and under voltage protection circuitry and over power protection circuitry is implemented.

FEATURES

* Over voltage protection for 3.3V/5V/12V
