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
Digital Isolator
This product is not recommended for new designs.
The I13TL1A0 is a three-channel passive digital isolator which enables secondary-referenced digital power-system monitoring and control when used in conjunction with the Vicor digital supervisor (D44TL1A0) and high-performance power conversion, regulation and transformation modules and bricks. The I13TL1A’s passive design reduces system complexity, while its small footprint increases system power density.
