    This is in relation to my other thread, BUT it's different due to being a stand alone unit.

    These chips can regulate down to 1.1v and up to 4.5v and apparently can supply over 35A. So it's exactly what I need, and it's used for CPUs so that's even better. Now the evaluation kit comes preset at 2.5v@8A, which is close to the 2.9v I need it to do, but a far cry from the 35A I'd need.

    Anyways, here's the documentation on the assembled regulator

    Doc on the chip itself

    Older versions if anyone thinks it'd be better to use for which ever reason
    Kit(1625 is the non-programmable version, 1624 is programmable, which ever would be best):

    I hope this isn't too big of a task :\ I don't understand the fine details of this sort of thing, so I can't really grasp the complexity of doing something as what I'm asking.

    Thanks!
