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. The frequency is thus reduced by

stepping into successive valleys until the number 4 is reached. Beyond

this point, the frequency is linearly decreased in valley−switching

mode until a minimum is hit. Valley lockout during the first four

drain−source valleys prevents erratic discrete jumps and provides

good efficiency in lighter load situations.
