onsemi, 5-Channel Switching, Flyback Controller, 4.9V 140 kHz, SOIC 8-Pin

The ON Semiconductor NCV1362ABDR2G is a highly integrated primary side quasi−resonant flyback controller capable of controlling rugged and high−performance off−line power supplies. This controller saves the secondary feedback circuitry for Constant Voltage and Constant Current regulation, achieving excellent line and load regulation without traditional opto coupler and TL431 voltage reference. The NCV1362 operates in valley lockout quasi−resonant peak current mode control mode at high load to provide high efficiency.
