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−resonant peak current mode control mode at nominal load to provide high efficiency. When the secondary−side power starts diminishing, the switching frequency naturally increases until a voltage−controlled oscillator (VCO) takes the lead, synchronizing the MOSFET turn−on in a drain−source voltage valley.
