Product Summary

The STR-W6253D is power IC for switching power supplies, incorporating a power MOSFET and a current-mode type PWM controller IC. The low standby power is accomplished by the automatic switching between the PWM operation in normal operation and the burst-oscillation under light load condition. The STR-W6253D achieves high cost-performance power supply systems with few external components. The applications of the STR-W6253D are Home Appliances (White Goods), Digital Consumer Equipment, OA Equipment, Industry Machines, Communication Devices, Others.

Parametrics

STR-W6253D general specifications: (1)fosc: 67kHz; (2)MOSFET VDSS(MIN): 650V; (3)RDS(ON)(MAX): 1.9Ω.

Features

STR-W6253D features: (1)current-mode type pwm control; (2)pwm with jittering function; (3)the function reduces the emi noise and enables simplified (low-cost)emi filter; (4)the jittering period is adjustable by an external capacitor; (5)auto-standby function; (6)the burst-oscillation enables the low standby power; (7)input power pin < 100mw at no load; (8)built-in startup circuit, enabling low power consumption; (9)overcurrent protection (ocp)with built-in input compensation circuit; (10)the function has less ac input voltage dependency; (11)overload protection (olp)with built-in delay timer ( the delay time is adjustable by an external capacitor); (12)external latch protection (elp); (13)the function enables the latch shutdown by external signal; (14)bias-assist function, reducing operating vcc voltage drop; (15)the function improves the startup operation and makes a low vcc capacitor applicable; (16)leading edge blanking function; (17)slope compensation function; (18)built-in avalanche energy guaranteed high-voltage power mosfet.
