Abstract
Embodiments described herein relate to a circuit including a DC-to-DC converter and a switching device to selectively isolate an input voltage from an input node of the DC-to-DC converter. The circuit also includes a controller coupled to the input node and to the switching device. The controller is configured to apply a test voltage to the input node, to enable the switching device to be switched from a non-conductive state to a conductive state if a voltage on the input node is above a threshold while the test current is applied to the input node, and to restrict the switching device from being switched from the non-conductive state to the conductive state if the voltage on the input node is below the threshold while the test current is applied to the input node.
