DISTRIBUTED POWER DELIVERY TO A PROCESSING UNIT

摘要

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.
