onsemi NCP13616
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. 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.| Part No. | NCP13616 |
