Abstract
A system and method for providing direct-current power is described. In one embodiment a direct current voltage is converted into at least two regulated DC voltages, and a first of the at least two regulated DC voltages is applied across a first and second outputs and a second of the at least two regulated DC voltages is applied across the second output and a third output. And when a first impedance across the first and second outputs is less than a second impedance across the second and third outputs, current is received via the second output while delivering power to the first and second impedances.
Claims6
An apparatus comprising:
- a switch-mode regulator including a first, second, and third outputs, the first and second outputs configured to connect to a first load and the second and third outputs configured to couple to a second load, wherein the regulator is configured to apply, using a first direct-current voltage, a regulated second DC voltage between the first and the second outputs and a regulated third DC voltage between the second and third outputs, each of the regulated second and third DC voltages having a magnitude that is less than the magnitude of the first DC voltage;
- wherein the switch-mode regulator is configured to receive current from the second output, while providing power to the first and second loads, when an impedance of the first load is less than an impedance of the second load and the regulator is configured to send current out of the second output when the impedance of the second load is less than the impedance of the first load.
