FUNCTION DESCRIPTION
The SD6109 is a power management IC for computers. It integrates various monitoring functions and protections,
such as AC fail detection, over power protection, negative voltage protection, over/under voltage protection and
provides power down signal for PG. Built-in high precision oscillator provides accurate protection and delay time
for monitoring. And internal regulators TL431 are used for stable output 3.3V and 5V, with few peripheral
components. Built-in soft-start decreases stress of transformer against saturation. SD6109 used for pull-push or
half-bridge power system with high efficiency and stability.
