From the previous calculations, you need at least 18.75
F in order to achieve the specified ripple level at the
conditions stated. Practically, a capacitor that is one level
larger is used to accommodate factors not taken into
account in the calculations. Therefore, a capacitor value of
22 F is selected. The NCP1422 is internally compensated
for most applications, but in case additional compensation
is required, the capacitor C4 can be used as external
compensation adjustment to improve system dynamics.
In order to provide an easy way for customers to select
external parts for NCP1422 in different input voltage and
output current conditions, values of inductance and
capacitance are suggested in Figures 24, 25 and 26.
