Design me a Product SMPS using PWM

I have already 220VAC input, 12V 20A output converter design If you want, I will send you picture of schematic layout free. I have not only Schematic circuit, but also PCB layout written by "Altium Designer" program

A proposal has not yet been provided

5 Years of Experience in designing AC-DC power converters with multiple outputs. Our plan is to propose the best possible optimized solution with lowest BOM and manufacturing costs. We will select the best suited topology after we get a clear idea of the efficiency and other specifications required by you based on which the final design will be proposed. The transformer required would be a multiple output flyback transformer. For further discussion, please contact me at 9764005053. Shashank

SMPS with 5,10 Amps of current ratings can be easily done...

i will do it and send to you one piece as a sample

I'm a electronics engineer with a strong knowledge in PCB design. I can do your design using the most high technology.
