I am new in SMPS system. I have only theoretical idea (no practical). I have made the 12 Volt 1Amp rating SMPS with ST Viper22 PWM controller and found excellent result. But i want to built SMPS only with discreet PWM current mode controller (UC3844/45) and power mosfet, which is readily available in our market. So I request you to give me circuit schematic with all details of the transformer (core, turns, wire size etc) and design equation of a practically built and tested SMPS ( 12 volt 4 Amp flyback), so that I can built the full proof system easily.
Please tell me the price for provide one prototype board for the same with two extra transformer.
