SD4871 Datasheet (Silan Microelectronics) - CURRENT MODE PWM CONTROLLER

SD4871, CURRENT MODE PWM CONTROLLER

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
