An electrical power supply device (10) comprises a DC-DC power convertor (14) and a device controller (16) in communication with the DC-DC power convertor (14). The DC-DC power convertor (14) receives an input voltage (30) and produces a first output voltage (24) or a second output voltage (24) that is less than the first output voltage (24), the first and second output voltage (24) each less than the input voltage (30). The device controller (16) has one or more processors and memory. The memory includes instructions which causes the device controller (16) to command the DC-DC power convertor (14) to output the first output voltage (24) when the input voltage (30) is equal to or greater than a threshold voltage (32) and which causes the device controller (16) to command the DC-DC power convertor (14) to output the second output voltage (24) when the input voltage (30) is less than the threshold voltage (32). The DC-DC power convertor (14) is incapable of providing an output voltage (24) that is greater than the input voltage (30), wherein the electrical power supply device (10) is disposed within an automobile having a start-stop controller (20) in communication with the device controller (16). The memory further includes instructions which cause the device controller (16) to command the DC-DC power convertor (14) to output the first output voltage (24) in accordance with the device controller (16) receiving a run signal from the start-stop controller (20). The memory additionally includes instructions which cause the device controller (16) to command the DC-DC power convertor (14) to output the second output voltage (24) in accordance with the device controller (16) receiving a stop signal from the start-stop controller.
