SD6109

www.DataSheet4U.com 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 FEATURES * Advanced Bi-CMOS process. *4KV HBM ESD protection * Bipolar structure adopted in Shunt regulators TL431, with high reliability * Over voltage protection for 3.3V/5V/12V * Under voltage protection for 3.3V/±5V/±12V * Over power protection * Short circuit protection * AC-input under voltage protection * PG Circuit * PSON for remote control * Delay time for PSON or PG signals * Two bypass regulators for 3.3V and 5V- voltage stability * Soft start and maximum 93% duty cycle APPLICATIONS * Switching mode power supply for computers.
