Powering AI processors – 48V vertical power delivery changes the game
AI models demand huge current, driving legacy multiphase designs past 50 phases—causing space, thermal, and control limits Vicor addresses
DCM™ DC-DC converter
High-density power modules for bridging 48V and legacy 12V power buses
Vicor non-isolated, regulated DC-DC converter modules operate from a 40 – 60V input, generate a regulated 12V output, and are adjustable from 10V to 12.5V. They support up to 2000W and can be paralleled to attain higher power levels. They are complete converter solutions requiring minimal external components, yielding even higher power density for the complete power delivery network. The DCM has established a new benchmark for power density with a low-height, surface mount Converter housed in Package (SM ChiP), resulting in a 6x reduction in size over a conventional converter. With Vicor proprietary high frequency switching technology, these modules deliver high efficiency over all line and load conditions. They can be used to establish a 12V bus or used with legacy, downstream point-of-load (PoL) converters, and are ideally suited for bridging 48V and legacy 12V power buses in industrial, aerospace and defense, and high performance computing applications.
Vicor also manufactures DCM isolated, regulated DC-DC converters.
