In some cases where there are oscillations on the output
due to the input/output combination, output load variations
or PCB layout a snubber circuit on the SWE Pin will help
minimize the oscillation. Typical usage is shown in the
Figure 31. C3 values can be selected between 2.2 nF and
6.8 nF and R4 can be from 10 W to 22 W.
