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 power system with high
efficiency and stability.
DIP-20-300-2.54
