Claim 12:
13. A voltage source device comprising:
a voltage converter configured to generate a bus voltage at an output terminal of the voltage converter based on a feedback signal; and
a first circuit comprising:
a voltage monitoring circuit configured to verify that the bus voltage of the output terminal of the voltage source device is in a correct range;
a first switch coupled to a third switch and configured to control the third switch to selectively connect or isolate the output terminal of the voltage source device to or from, respectively, a supply voltage node of the 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.
