Product
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
µs fixed off-time, variable on-time)
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.
Auto burst standby: (No Load Consumption < 100 mW at AC 264V)
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.
Auto bias function
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 VCC voltage reaches VCC (OFF), thereby
stabilizing the entire power supply operation.
Integrated startup circuit
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.
Current mode control
Leading edge blanking
Not required the external Low-pass filter circuit which prevent the malfunction due to the leading
edge spike current.
Avalanche energy guaranteed MOSFET with high VDSS
The built-in power MOSFET simplifies the surge absorption circuit since the MOSFET guarantees
the avalanche energy.
No VDSS de-rating is required.
Various protecting functions
• Over current protection ------------ pulse by pulse
• Over voltage protection ------------ with latch
• Overload protection ---------------- Auto restart
• Thermal shutdown ------------------ with latch
