Low Power Offline Constant Current PWM Current-Mode Controller with/without High Voltage Startup Current Source NCP1361, NCP1366 The NCP1361/66 offers a new solution targeting output power levels from a few watts up to 20 W in a universal mains flyback application.

Due to a novel method this new controller offers a primary side constant current control, saving secondary side components to perform current regulation.

The NCP1361/66 operates in valley lockout quasi<
