This is Part 2 of our 3 videos about Input Capacitor sizing and selection for switch mode power supplies. In this video we show how to calculate exactly how much ceramic capacitance we need on our input in order to reduce our input voltage ripple to a specified value. In the next part we will do the same for Electrolytics
