I used the WEBENCH from National Semiconductor:

After keying the specs, WEBENCH recommended the following design:
http://webench.national.com/servlet/SS?VinMin=20&VinMax=28&O1V=12&O1I=8&op_TA=30

In the design, LM2642 was employed. I checked the websites of LM2642 ( http://www.national.com/pf/LM/LM2642.html ) and found few application notes on this buck regulator. Hopefully it helps. :)

maybe you can use a normal regulator with additional transistors in parallel with it to carry the current.

Re: 24volt to 12v 8 amp

If you follow advice from the last post you will built yourself a heater..

You can obviously construct a dc/dc converter but ... for about $30-50 you can get one of-the-shelf... hmmm...something to think about...
