MARKING

DIAGRAMS

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.

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. This technique keeps the output in

regulation with the tiniest dummy load. Valley lockout during the first

four drain−source valleys prevents erratic discrete jumps and provides

good efficiency in lighter load situations.
