Abstract
In accordance with an embodiment, a circuit includes a switch coupled between a first reference terminal and a first output terminal, an inductive element coupled between an input terminal and a second output terminal, and a diode coupled between the first output terminal and the input terminal. The circuit further includes a controller coupled to a control terminal of the switch. The controller is configured to determine a switching signal based on an output signal at the second output terminal and provide the switching signal to the control terminal of the switch.
