Low Power Offline Constant Current & Constant Voltage Primary Side PWM Current-Mode Controller with/without High Voltage Startup Current Source NCP1360, NCP1365 The NCP1360/65 offers a new solution targeting output power levels from a few watts up to 20 W in a universal−mains flyback application. Thanks to a novel method this new controller saves the secondary feedback circuitry (opto−coupler and TL431 reference) while achieving excellent line and load regulation. The NCP1360/65 operates in valley−lockout quasi−resonant peak current mode control mode at nominal load to provide high efficiency.
