Lastly, R
c
needs to be selected. A good practice is to use a 50-k
potentiometer and adjust the potentiometer for
the best load transient where no oscillations should occur. These tests have to be done at the highest V
in
and
highest load current because the converter stability is most critical under these conditions. Figure 20, Figure 21,
and Figure 22 show the fine tuning of the loop with R
c
.
