Battery Charger ---------------------- Cell Phone, Digital Still Camera, Camcorder, Shaver, Emergency light, Guidance light, and etc.

Standby Power Supply --------------- Various TV applications, PC, LBP, Audio system and etc.

S.M.P.S. -------------------------------- Ink jet printer, DVD Player/ Recorder, VCR, Set Top Box and etc.

Controller Power Supply ------------ Air conditioner, Refrigerator, Washer, Dish Washer and etc.

PRC 〔Pulse Ratio Control〕 : (8 s fixed off-time, variable on-time)

Auto burst standby: (No Load Consumption < 100 mW at AC 264V)

Auto bias function

Integrated startup circuit

Current mode control

Leading edge blanking

Avalanche energy guaranteed MOSFET with high V

Various protecting functions

The switching frequency varies within an optimum range of 63kHz to 120kHz, according to load

variations, to create a quasi-jittering, low-EMI noise operation.

Enables very low power consumption at no load.

Typical results of a 5W universal input power supply are 35mW at AC110V and 43mW at AC220V.

This function stabilizes operation during Auto Burst Standby mode, by preventing a Hiccup mode.

The Auto Bias function forces the IC to turn on before the V

stabilizing the entire power supply operation.

600 V BCD process allows direct connection of the STARTUP pin to the rectified high voltage

rail. This reduces component count and improves overall efficiency.

Not required the external Low-pass filter circuit which prevent the malfunction due to the leading

edge spike current.

The built-in power MOSFET simplifies the surge absorption circuit since the MOSFET guarantees

the avalanche energy.

No V

• Over current protection ------------ pulse by pulse

• Over voltage protection ------------ with latch

• Overload protection ---------------- Auto restart

• Thermal shutdown ------------------ with latch
