• NCP1365XS1GEVB, Evaluation Board is designed to efficiently evaluate the NCP1365 which offers a new solution targeting output power levels from a few watts up to 20W in a universal-mains flyback application. Thanks to a novel method this new controller eliminates the need for a secondary feedback circuitry while achieving excellent line and load regulation. The NCP1365 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
