This would be a variable (digital programming) buck converter. Curr= ent will be about 10A max, usually less. Output noise and somewhat poor re= gulation are acceptable to me in this case. Obviously I'd also be running = it at 10's of kilohertz as well to mitigate some of the concerns. Is it re= asonable if I use a proto-board with a ground plane? I know this is usuall= y somewhat problematic. Thanks.
