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
DC-DC converters provide superior power system performance and connectivity
The Vicor DCM4623 family are isolated, regulated DC-DC converters, operating from an unregulated, wide range input to generate an isolated output. With its high frequency zero voltage switching (ZVS) topology, DCMs consistently deliver high efficiency across their specified input line range. Modular DCM converters used independently or with downstream point of load (PoL) products support efficient power distribution, providing superior power system performance and connectivity from a variety of unregulated power sources to the point-of-load.
