TECHNICAL FIELD OF THE INVENTION
tomotive applications have used a "buck/boost" DC-DC
power converter to generate voltages from 5 volts to 20
[0001] The invention generally relates to an electrical 5 volts which are both above and below the typical vehicle
power supply device and method of operating the elec-
input voltage of 12 to 14 volts. Buck/boost DC-DC con-

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). A method (100) of operating the electrical power supply device (10) is also presented.
(54) ELECTRICAL POWER SUPPLY DEVICE AND METHOD OF OPERATING SAME
(57) An electrical power supply device (10) includes a DC-DC power convertor (14) receiving an input voltage (30) and producing 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) and a device controller (16) in communication with the DC-DC power convertor (14). The device controller (16) has one or more processors and memory. The memory includes instructions which
