I inherited some simple switcher designs... the output capacitors are way too big....like 10 times larger than recommended. Should I worry?
The output voltages look pretty quiet and well regulated.
I suspect the controllers might be running in a bang bang mode because the loop compensation is so screwed up.
So these switchers are probably more noisy on the input side than they could be...
And of course the layout area is much larger than it needed to be with the 10 times capacitance.
However the folks around me say if it ain't broke don't fix it. Any thoughts?
