The ME8226B is a highly integrated current mode PWM controller optimized for high performance off-line power converters. VDD low startup current and low operating current contribute to a tiny power consumption and reliable power on startup. ME8226B features a auto-tuning circuit combined with a steering charge pump，ensuring stable driving speed for various Qg conditions without any external resistor. ME8226B offers a wide VDD supply range from 9.6V to 52V. The IC operates in a maximum frequency of 70KHz @Full Load, As the load gradually decreases ，the IC operates in Green Mode and Extended Burst Mode to minimize the standby power loss. EMI performance is also optimized by Frequency Jittering and Peak Current Jittering. ME8226B offers comprehensive protection coverage including Cycle-by-Cycle current limiting（OCP），Over Load Protection（OLP），VDD Under Voltage Lockout （ UVLO ）， Over Temperature Protection（OTP），VDD Over Voltage Protection（VDD OVP），Leading Edge Blanking（LEB）and CS open Protection（SCB）.
