Gain, Window Width, and Gain Ratio Adjustments
19. When extra load transient response improvement is needed, adjust the Gain
and/or Gain Ratio and Window Width. The following traces show examples of
the process used to obtain optimum transient response settings. The step
that increases Gain may be skipped in favor of Window Width and Gain Ratio
adjustments only.

20. Figure 5-4 shows the transient response with the Gain Ratio and Window
Width disabled. In this example Gain is 1.235; Reset is 0.28, and
Compensation is 0.88. Load step is ~15%.
