Mathcad Calculates Input Capacitor for Step-Down Buck Regulator

Abstract: Step-down buck regulators are extremely popular in a variety of portable and non-portable
equipment. These buck converters are terminated with an input capacitor, CIN and an output capacitor, CO, at
the output. CIN provides high-frequency filtering, so that VIN has low ripple. This application note helps a
system designer to set-up Mathcad and compute CIN for a particular step-down DC-DC regulator design.


Step-down buck regulators are used in portable and non-portable equipment, such as PDAs, cell phones,
