I cant find any information on DC to DC power supplies. Can anyone help me ?

Thanx

 

I would start by Googling "dc-dc converters" and "switching regulators".

It may be of help.

Thanx

I was a little confused on whether these types of PSUs worked exclusively on DC. A little more research will uncover this hopefully.

 

Well, there are lots of PSUs called "Off-line" SMPS (switch-mode power supplies), meaning their source of power is the AC mains, i.e. "line" voltage. There are tons of good dc-to-dc converter Application Notes at the websites of the SMPS controller-IC manufacturers, such as ti.com, national.com, linear.com, and others. I think that TI also still has the old Unitrode appnotes on line, too.
