Description
The HS8108 is a power supply switching mode controller IC 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. A built-in timer generates accurate timing for control circuit including the PS-off delay. […]
