PRODUCTION DATA.
Select a ceramic output capacitor to limit the capacitive voltage ripple at the converter output. This is the sinusoidal ripple voltage that is generated from the triangular inductor current ripple flowing into and out of the capacitor. Select an output capacitance using Equation 21 to limit the voltage ripple component to 0.5% of the output voltage.
Substituting ΔIL(nom) of 250-mA gives COUT greater than 3.1 μF. With voltage coefficients of ceramic capacitors taken in consideration, a 22-µF, 25-V rated capacitor with X7R dielectric is selected.
