the best flyback SMPS i could make.
Specs:
Pin = 190W
Pout = 120W
Eff. = ~63%
Iin = 0.58A
Iout = 10A
Vout = 12V
Vripple = ~150mV with resistive load
Info:
It works at 100Khz and uses two comparators one as error amplifier and one as pwm comparator. It can probably be replicated with an uc384x family chip and a 900V ~10A mosfet. I think an atx transformer can be enough for this purpose
