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 V CC 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. ˔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 V DSS de-rating is required. ˔Various protecting functions
