I need help from someone very experienced in making and designing smps .
I am myself electronics hardware engineer but now I need to design a very good industrial smps .
Input 90vac to 250 vac
Output 5v 4 amps.
Output voltage ripple : +- 5%
Type : flyback opto isolated .
Pcb : 4 layers .
Good emi input filter .
Teach me how to design smps , how to design transformer , how to design the feedback circuit .
I will make , test , develop the smps .i will develop the pcb , order the components , solder the pcb , talk to the transformer manufacturer .
I will read whatever documentation you send me .
You should have in depth knowledge of flyback smps .
Rest , I will learn everything from you ,
