SD4872 Datasheet (Silan Microelectronics) - CURRENT MODE PWM + PFM CONTROLLER

SD4872, CURRENT MODE PWM + PFM CONTROLLER

SD4872X 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
