SM8023 is a low-power current-mode PWM control chip off-line, direct-drive external high voltage MOS transistor. Adaptive multi-mode work, depending on the load, automatically switches to Burst Mode, PFM mode or PWM mode, to meet the system's low standby power consumption, high conversion efficiency requirements. Internal integration of multiple protection features such as over-current protection, overload protection, VDD and VDD undervoltage overvoltage protection and other protection. Features For less than 36W switching power supply system standby power consumption less than 80mW220Vac built-optimized adaptive multi-mode OCP compensation, depending on the load, automatically switches to Burst Mode, PFM mode or PWM mode built-in current leading edge blanking (LEB) built-in slope compensation circuit-by-cycle peak current limit soft start with boot overcurrent protection, overload protection, VDD over voltage protection and other protection Package: SOT23-6 three: Applications DVD, DVB, LCD TV, printer power adapter LED PC Standby Power drive
