SD4871_Datasheet CURRENT MODE PWM CONTROLLER DESCRIPTION SD4871 is a current mode PWM controller IC for high performance, low standby power offline flyback converter application. In no load or light load condition, the IC operates in Light Load Mode to reduce switching loss and improve efficiency. Large startup resistor could be used in the startup circuit to minimize the standby current because of low startup current. SD4871 offers complete protection functions including cycle-bycycle
