Abstract
This paper presents a novel method for the design of input filter capacitors of dc-dc switching regulators, using a combination of ceramic and electrolytic capacitors. The method is based on the definition of Acceptability Regions, which allow a straightforward identification of minimal size and part count commercial components complying with input voltage ripple specifications. Examples regarding the optimal selection of capacitors for the input filter for low-voltage/high-current buck dc-dc switching regulators are illustrated.
