Abstract
A controller circuit is configured to drive a switching element to establish a channel that electrically couples a source to an inductive element of a buck converter and generate a minimum current sample. In response to current at the switching element exceeding a target peak current threshold of a set of control parameters for the buck converter, the controller circuit is configured to generate a peak current sample, calculate a mean current using the minimum current sample and the peak current sample, and modify the set of control parameters using the mean current. In response to the switching element satisfying an off time of the set of control parameters, the controller circuit is configured to drive the switching element to establish the channel that electrically couples the source to the inductive element during an on state for a subsequent switching period.
