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
Wide range direct to point-of-load regulators
The Vicor ZVS PI3740 Evaluation Board is a fully populated buck-boost board for PI3740-00 DC-DC ZVS buck-boost regulator. The evaluation board has a voltage input range of 8V to 60V, and an output of 24V. The ZVS PI3740 Evaluation Board has an excellent power output of 60W. The ZVS architecture maximizes efficiency while minimizing switching loss, and enables fast dynamic response to line and load transients.
