I was thinking that not going up then down, might work a little more
efficiently, though swithcing power supplies are generally very efficient.
 I'm trying to make the thing on one board, rather than have a lot of boards
strewn together.  That's okay, not mission critical just yet, I have time to
research & design the thing.

Probably not, in fact, pretty sure of it.  However if I design it right, it
would be one board instead of several, linked together.

Thanks for the input Tom :)
