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
LoPAC™ Family AC-DC and DC-DC Power Supplies
This product is not recommended for new designs.
New configurations are not available. Please use the Power System Designer tool to find a product for your project.
The LoPAC family consists of three ultra-low-profile, fan-cooled, switching power supplies that combine the advantage of power-factor correction (PFC) with high-power density. All units feature universal input and accept voltages from 85 to 264VAC , 47 – 500Hz or 100 – 300VDC (100 – 380VDC for the PFC Mini). Configured with highly reliable Vicor DC-DC converters (VI-2XX, VI-JXXand Maxi, Mini, Micro modules), the LoPAC family offers from one to six outputs and up to 1500W dependent on model and configuration.
