ABSTRACT:
A system may include a voltage regulator controller to provide a control signal, a voltage regulator converter comprising a power switching element coupled between an output node of the voltage regulator converter and ground, the voltage regulator converter to receive the control signal, and a logic circuit to detect current flow from the output node to the voltage regulator converter and to disable the power switching element in response to detecting the current flow.
