Designing Second Stage Output Filters for Switching Power

Typically with a second stage filter it is reasonable to get the ripple down to a few hundred V p p and the switching noise down below 1 mV p p. A buck converter can be made somewhat quieter since the power inductor provides significant filtering. These limitations are because once the ripple is down in the V the component parasitics, and noise coupling between filter stages starts to become the limiting factors.
