SD6109
VOLTAGE MODE PWM POWER SUPPLY WITH BUILT-IN SUPERVISOR, PROTECTION AND REGULATION FOR PCs
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 ...
