1. A first circuit comprising: a voltage monitoring circuit configured to verify that a bus voltage of an output terminal of a voltage source device is in a correct range; a first switch configured to control a third switch that selectively connects or isolates the output terminal of the voltage source device to or from, respectively, a supply voltage node of a voltage converter; and a second switch configured to mutually-exclusively couple an intermediate node to: the supply voltage node of the voltage converter during a first regulation mode; or the output terminal of the voltage source device during a second regulation mode.
