Output Capacitor Selection

The output capacitor is required to keep the output voltage ripple small and to ensure regulation loop stability. The

output capacitor must have low impedance at the switching frequency. Ceramic capacitors with X5R or X7R dielectrics

are recommended due to their low ESR and high ripple current.

Compensation Capacitor Selection

The compensation capacitors for increasing phase margin provide additional stability. It is required and more than 22p,

Refer to Demo Board Schematic, The optimum values for C4 is 47pF.
