Minimum desired switching frequency at
selected values for V
Desired peak-to-peak output ripple volt-
age. In practice, the calculated value will
need to be increased due to the capacitor
equivalent series resistance and board
layout. The ripple voltage should be kept
to a low value since it will directly affect
the line and load regulation.
