I'm designing a full bridge rectifier that takes 110vAC to 4-16vDC for input into a 5v switching regulator.
I opened a few 5v power supplies and they place the bridge on the high voltage side. Why not use the low voltage size so the diodes are smaller/cheaper?
Also, I notice they use an IC on the high voltage side, what is the purpose of that IC and is it required?
Most circuits I see online are basic like this one which should give me full wave recification:
This is the transformer I'm using: http://catalog.triadmagnetics.com/Asset/FS10-600-C2.pdf
