DESCRIPTION
SG6105A controller is designed for switching-mode
power supplies 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, and protection features against
over-voltage and over-power are implemented. It
directly senses all the output rails for OVP without
the need for external dividers. An innovative
AC-signal sampling circuitry provides a sufficient
power-down warning signal for PG.
A built-in timer generates accurate timing for the
control circuit, including the PS-off delay. The
cycle-by-cycle PWM switching prevents the power
transformer from saturation and ensures the fastest
response for the short-circuit protection, which
greatly reduces stress for power transistors. Two
internal precision TL431 shunt regulators provide
stable reference voltage and a driver for 3.3V and 5V
standby regulation.
Utilizing
SG6105A includes the functions for push-pull and/or
half-bridge topology, decreasing production cost and
PCB space, and increasing the MTBF for power
supply.
