Abstract
Technology is provided for distributed power delivery to a processing unit on a printed circuit board. In one example, a printed circuit board includes a processing unit coupled to multiple power channels, including first channels on a first side of the processing unit, and second channels on a second side of the processing unit. The printed circuit board further includes a first power supply coupled to the processing unit via the first channels, and a second power supply coupled to the processing unit via the second channels. The processing unit is configured to receive a total current, including currents drawn substantially simultaneously from the first power supply and the second power supply. The total current is about equivalent to a current the processing unit would draw from a single power supply.
Claims9
A printed circuit board comprising:
- a processing unit coupled to multiple power channels, including one or more first channels on a first side of the processing unit, and further including one or more second channels on a second side of the processing unit;
- a first power supply disposed on a first side of the processing unit, coupled to the processing unit via the one or more first channels, and configured to supply half of a total current received by the processing unit;
- and
- a second power supply disposed on a second side of the processing unit that is directly opposite to the first side, coupled to the processing unit via the one or more second channels, and configured to supply half of the total current received by the processing unit,
- wherein the processing unit is configured to receive each half of the total current substantially simultaneously from the first power supply and the second power supply, and the processing unit is disposed directly between the first power supply and the second power supply.
A distributed power supply for a processing unit on a printed circuit board, the distributed power supply comprising:
- multiple power channels coupled to the processing unit, wherein the multiple power channels include one or more first channels on a first side of the processing unit, and further include one or more second channels on a second side of the processing unit;
- a first power supply disposed on a first side of the processing unit, coupled to the processing unit via the one or more first channels, and configured to supply half of a total current received by the processing unit;
- and
- a second power supply disposed on a second side of the processing unit that is directly opposite to the first side, coupled to the processing unit via the one or more second channels, and configured to supply half of the total current received by the processing unit,
- wherein the processing unit is configured to receive each half of the total current substantially simultaneously from the first power supply and the second power supply, and the processing unit is disposed directly between the first power supply and the second power supply.
