Abstract
An example power supply circuit includes a boost converter and a feedback control circuit. The boost converter generally includes an inductive element coupled between an input voltage node and a switching node, a first switch coupled between the switching node and a reference potential node, a second switch or a diode coupled between the switching node and an output voltage node. The feedback control circuit has a first input coupled to the output voltage node and has an output coupled to at least a control input of the first switch. The feedback control circuit generally includes a voltage node configured to influence a duty cycle of the boost converter; and a feedforward path coupled to the voltage node and configured to have a voltage signal derived from at least one of an input voltage at the input voltage node or an output signal at the output voltage node.
