Hello All,
I need to design a power block to supply my processor board and it should be a compact one...The input will be 230V AC and output to be expected is 12V 3A. I have seen some reference design from Monolithic systems for this, it seems that >10W needs a transformer...If it is right, what are the reasons which require a transformer for >10W supply design...Please suggest.
Thanks,
Sangar
