If 1A would not be enough you can use the LM2576 or LM2596. I have built a couple of boards with the LM2576 and LM2596. These are 3A switch mode regulators, similar to the LM2575. I quite like them as they are cheap and easy to find. I have only used through the hole components in my designs so far, but working on a board with only smd parts. My biggest problem was finding the right inductors, eventually I got some on Ebay.

I know its a old post, but this PSU looks really interesting, i am a beginner, and if possible, please post this PSU schematic? I really like to study this one!
