SC6105
VOLTAGE MODE PWM POWER SUPPLY WITH BUILT•IN SUPERVISOR,
PROTECTION AND REGULATION
DESCRIPTION
The SC6105 is
computers. It can regulator the output voltages by providing PW
signals to drive transformer. nItitorsmo and protects
a switching mode power supply controlle
a
3.3V/±5V/±12V outputs. Two internal TL431 shunt regulators provide
stable reference voltage for 3.3V and 5V•standby regulaotr. Remote
ON/OFF control, power good circuitry, over voltage and
voltage protection circuitry and ovepr ower protection circuitry
implemented.
