The addition of the C
OUT
is essentially increasing the amount of energy that can be stored in the output
stage, which also means it can supply current for an increased period of time. Therefore by slowing
down the di/dt transients in the load, the frequency is effectively decreased.
With the C
OUT
capacitor, the inductor current is no longer identical to that seen in the load. The
inductor current will still have a perfectly triangular shape, where as the load will see the same basic
trend in the current, but all sharp corners will be rounded with all peaks significantly reduced, as can
be seen in Figs. 14 & 13.
