10.4 Load Transient Response (75% to 100% Load Step)
In the following two oscilloscope screen shots (Figures 17 and 18), signal averaging was
used to more clearly capture the output voltage response to a load transient. Averaging
minimizes the appearance of the 400 kHz switching ripple in the output voltage scope
plot. The load current step was used to trigger the horizontal sweep of the oscilloscope.
