Probably be better than most of the cheap buck converter modules from eBay/=
Aliexpress.

Remember, any switching regulator needs to have output ripple in order to r=
egulate. Otherwise how would you control the duty cycle of the switch? If y=
ou need low ripple, you must use a secondary filter.

Cheers, Bob

Is it at all reasonable to build a switching power supply on a perf board? =
 I plan to use heavy gauge wire and properly fix the location of all compon=
ents.  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.
