[380] 30 Watt SMPS Design, Explained Circuit Diagram PSAA30R Series Adapter

in this video i explained 30 Watt SMPS Design, Explained Circuit Diagram PSAA30R Series Adapter, it use current mode smps controller SMD code FF-K14, it receives vcc voltage 22.8 VDC at vcc pin, it is green mode energy saver IC, TL431 adjustable zener regulator is used to drive PC817, which provides feedback to SMPS PWM controller IC. this IC drives 4N60 MOSFET to drive transformer primary winding. this video covers PSAA30R-560 56 Volt 0.54 Amp and it will also helpful in following circuit designs, you can get idea with minor changes in the diagram for other designs:-
PSAA30R-120 12 volt 2.5 Amp
PSAA30R-150 15 Volt 2 Amp
PSAA30R-240 24 Volt 1.25 Amp
PSAA30R-560 56 Volt 0.54 Amp
