Abstract
A circuit and method for providing an improved efficiency for a DCDC converter. A power converter, comprising a buck converter comprising an adaptive output, an adaptive transconductance block configured to evaluate resistive power terms, a multiplier block configured to provide capacitive power terms, and a comparator configured to compare resistive power and capacitive power terms for determining the selection of the branches of said adaptive output. The method for improved efficiency includes providing a switching converter with an adaptive output stage comprising the steps of providing a switching converter, evaluate capacitive power loss, evaluate resistive power loss, compare capacitive power loss and resistive power loss, and lastly adapting the output stage size.
