The document describes the SG6105A controller, which 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, PG delay time, and remote ON/OFF delay.
The SG6105A is a controller designed for switching-mode power supplies in desktop PCs, including AT, NLX, and SFX form factors. It integrates functions for monitoring and controlling power supply outputs, featuring remote ON/OFF control, power-good circuitry, and protection against over-voltage and over-power conditions. The device directly senses all output rails for over-voltage protection without requiring external dividers.
