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
Powering modern rail systems
The Vicor lower-power DCM2322 is an isolated and regulated DC-DC converter that operates from an unregulated, wide-range input to generate an isolated 12VDC output. The unit can produce up to 60W, or 5A of continuous current, with a maximum efficiency of 89.7%. Its high-frequency, zero-voltage switching topology allows for a low-profile design with high-density filtering. Two modes of operation are possible: the 60W standalone mode and the array mode, which permits up to eight combined units for producing a total 480W. Offered in a 2322 through-hole ChiP package, this product offers flexible thermal management options with very low top-side and bottom-side thermal impedance.
