Abstract
A DC-DC voltage converter is provided that includes a plurality of power channels and a controller. Each power channel is configured to provide a voltage output to an output node of the converter. Each power channel also includes a first sensing circuit configured to provide a primary feedback signal indicative of an output current of the power channel. Each power channel further includes an auxiliary sensing circuit to provided one or more auxiliary feedback signals indicative of an output current of each of the respective other power channels. The controller is configured to control each of the power channels based at least in part on the primary feedback signal and the one or more auxiliary feedback signals.
