Overview
SM7205 is a high-performance, low-standby power primary-side feedback control power switch for offline low-power AC/DC switching power supplies. It integrates a high-voltage 730V power MOS and achieves high-precision constant voltage output within the full voltage input range. The accuracy is less than ±5%, and the standby power consumption is less than 30mW@230Vac. It does not require loop compensation, which can save components such as optocouplers and TL431 in the system, reduce costs, and provide quasi-resonance and frequency jittering functions to improve the EMI characteristics of the system, while meeting the sixth level of energy efficiency.
