Here's something I came up with a little while back - http://www.diyaudio.com/forums/showthread.php?s=&threadid=85947&highlight=
If you make a discrete comparator that can current couple to the high side driver then you'd have a discrete self oscillating buck regulator, in theory and simulation. I haven't tried to build it yet.

I have a lot of experience with halh-brdge by now and I have a broken smps, i thin it is a fly, mains power.It is/was 9v charger, bet fuse burned out, nothing other seems to be wrong. That fuse is in series with 230Ac. So in time fuse got smaller (not in size ) and blow at some point.
I barely rmemeber posting to to that thread and never saw it again until now. Hadn't set up preferences in my user profile yet, and never received notices of subsequent postings to the thread.
I will go to the ARRL website and re-download the 13.8V 40A SMPS article and shotgun it around as requested, starting with Luka.
Cheers everyone.
