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
