Abstract

An apparatus includes a plurality of pulse control circuits and a control circuit. A given pulse control circuit of the plurality of pulse control circuits may source a current pulse to the output power signal based on a comparison of a particular feedback signal of a plurality of feedback signals and a target voltage signal. The control circuit may offset a voltage level of each feedback signal of a first subset of the plurality of feedback signals. The first subset may exclude a first feedback signal. In response to a determination that a period of time has ended, the control circuit may offset a voltage level of each feedback signal of a second subset of the plurality of feedback signals. The second subset may include the first feedback signal and exclude a second feedback signal.
