Automotive Primary Side

Flyback Controller

NCV1362

The NCV1362 is a highly integrated primary side quasi−resonant

flyback controller capable of controlling rugged and

high−performance off−line power supplies.

Thanks to a Novel Method this new 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.

When the power on the secondary side starts to diminish, the

controller automatically adjusts the duty−cycle then at lower load the

controller enters in pulse frequency modulation at fixed peak current

with a valley switching detection. This technique allows keeping the

output regulation with tiny dummy load. Valley lockout at the first 4

valleys prevent valley jumping operation and then a valley switching

at lower load provides high efficiency.
