C capacitor chart. Dividing 80mV by 20A gives 4mV/A
transient voltage deviation per amp of transient load setp.
Select 4mV/A on the Y-axis and read across to the “With
TurboTrans” plot. Following this point down to the X-axis gives
us a minimum required output capacitance of approximately
1700µF. The required R
be calculated or selected from the below table. The required

To see the benefit of Turbo Trans
across to the “Without TurboTrans” plot. Following that point
down shows that you would need a minimum of 5500µF of
output capacitance to meet the same transient deviation limit.
This is the benefit of Turbo Trans
