Buck Converter Output Capacitor Value Calculation

How to calculate minimum output capacitance required for the buck converter.. It will be similar to other DC to DC converters also like Book Converter, Buck-Boost converter, SEPIC Converter.... By replacing the required values from the converter input specifications in the capacitor equation, we can find the minimum required capacitor value in the SMPS converter...
