DESCRIPTION
SG6105 controller is designed for switching mode
power supply for desktop PCs. It provides all the
functions necessary to monitor and control the output of
the power supply. Remote ON/OFF control, power good
circuitry, some protection features against over-voltage
and over-power are implemented. It directly senses all the
output rails for OVP without the need of external dividers.
An innovated AC-signal sampling circuitry provides a
sufficient power-down warning signal for PG. A built-in
timer generates accuracy timing for control circuit
including the PS-off delay. The cycle-by-cycle PWM
switching prevents the power transformer from the
saturation and ensures the fastest response for the
short-circuit protection which greatly reduce the stress for
power transistors. Two internal precision TL431 shunt
regulators provide stable reference voltage and driver for
3.3V and 5V-standby regulation. Utilizing minimum
number of external components, the SG6105 includes all
of the functions for push-pull and/or half-bridge topology,
decreasing the production cost and PCB space, and
increasing the MTBF for power supply.
