GREEN MODE PWM CONTROLLER

The AP31251 is a current mode PWM controller which is optimized for high performance, low standby power and cost effective offline flyback converters.\n\n The PWM switching frequency at normal operation is internally fixed (about 65kHz). In middle load, the IC will enter green mode to improve s •Very Low Start-Up Current\n•Current Mode Control\n•Non-Audible-Noise Green-Mode Control\n•Internal Slope Compensation\n•Soft Start during Startup Process\n•Frequency Fold Back for High Average Efficiency\n•Secondary Winding Short Protection with FOCP\n•Soft Switching (Soft Driver and Smart Jitter) ;
