Current Multipliers: The Obvious Choice for Powering AI Processors and Other Demanding Applications

Tom Curatolo, Industrial BU Apps Engineer, Vicor

AI processors can draw up to thousands of amps while operating at voltages well below 1V. This current demand is unprecedented and has turned the power delivery network (PDN) into a major system bottleneck. With every amp pushed through PCB or substrate copper power planes, conductive losses and, thermal m
