Dear
I need a supply that could provide 12VDC/350ma and it should be small and cost effectiveness as well.
I have done many searches and found several circuits but I don't know how it works and how I could get optimum it.
I was wondering if you'd mind helping me understand how I can design a good one.
Thanks
Ehsan

The simple rule applied by all safety regulations is to consider circuit parts without sufficient insulation related to the mains voltage as hazardous contact voltage. You don't need to think about live or neutral connection in this regard.Few words of warning
DANGERexample of isolated transformless power supply...
max current 100mA
hope this helps
