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
IAM™ input filter
for VI-200/VI-J00
The IAM (Input Attenuator Module) is a component-level, DC-input front-end filter designed to occupy minimum board space while providing maximum protection for today's sophisticated electrical systems. The IAM in combination with 24, 48 and 300VDC input modules, provides a highly-efficient, high-density power system with outputs from 1 to 95VDC and power up to 400W (expandable to 800W). Your system will benefit from the small size, efficiency and inherent reliability of Vicor component-level converters, while meeting the toughest demands of telecommunications and industrial power applications.
