I must say I am surprised by how many refer to problems with the LM2576
series switchers.

I must admit I didn't use them in a very normal way (producing 10A) but
found them very good even though I had not put any effort into layout (just
heavy gauge wires) and self wound inductors.

I must admit I used about 4 x 4700uF caps, but then I was pulling a lot of
juice, with no real ripple.

Did not check for EMI, but was used with audio gear and could only hear CPU
noise not PSU.

The inductors themselves tended to hum a little, but I wouldn't think that
would happen at lower loads.
