o PRC [Pulse Ratio Control] : (8 ccs fixed off-time, variable on-time) The switching frequency varies within an optimum range of 63kHz t0 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 universalinput power supply are 35 mW at AC110V and 43 mW 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 tum on before the Vcc voltage reaches Vcc (OFF), thereby stabilizing the entire power supply operation. Integrated startup circuit 600V 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. o 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
