SC6105

SC6105 VOLTAGE MODE PWM POWER SUPPLY WITH BUILT-IN SUPERVISOR, PROTECTION AND REGULATION 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. DIP-20-300-2.54 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 computer...
