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

* Under voltage protection for 3.3V/±5V/±12V

* Over power protection

* Short circuit protection

* AC-input under voltage protection

* Power good circuitry

* PSON for remote controller

* Delay time for PSON or PG signals

* Two shunt regulators for 3.3V and 5V-standby

* soft start and maximum 93% duty cycle

APPLICATIONS

* Switching mode power supply for computers.
