At a previous job, I had to test a buck converter for a very power-hungry DSP which had very stringent power supply requirements. I stumbled upon Jim Williams' app-note 133, decided to try it out for myself.
Turns out, the man knew what he was doing, who'da thunk. Anyway, considering mosfet technology has advanced and wanting to make the thing cheaper (not using that many expensive LT parts) I redesigned it with a non-discrete gate drive section and a small form-factor.
Results have been pretty good, Rise-time for a 0-100A slew is around 300ns(V2) and 600ns(V1) corresponding to over 1MHz of Bandwidth. Overshoot is nearly nonexistent and the falling edge, though a bit faster, presents some ringing. I'm quite sure that the ringing is from the converter used to test the board.
Projects (Altium) with schematics, board files and Bills of Materials are in the "files" section. Thanks for checking my project out!
