Hi all, I'm having a big fail when trying to make an LC filter for a CUI SPMS. There's nothing to the circuit. Here.
The problem is that no matter what I do to the Land or C's the output always has the same amount, (shape and size) of ripple. Here's a 'scope shot.
And here's the layout.
(I was having the same problem in an earlier layout, but thought it might be the lack of a good ground plane.. hence today's modification.)
I'm doing something stupid, 'cause no matter what I do nothing changes.
