Most flexible power delivery
Non-isolated regulated
Input: 8 – 60V
Output: 10 – 54V
Power: Up to 150W continuous
Peak efficiency: 97%
10.5 x 14.5 x 3.05mm
Compact, low loss, board mounted power delivery
Ideal point of load conversion occurs when the regulation VIN and VOUT are equal, and when high current delivery is as close as possible to the point-of-load. Vicor Factorized Power Architecture separates the dedicated functions of regulation and transformation into separate power modules – PRMs and VTMs – so that each can be optimized for the highest efficiency and density.
Non-isolated regulated
Input: 48V (36 – 75V)
Output: 48V (5 – 55V)
Power: Up to 600W
Peak efficiency: 98%
As small as 22.8 x 13.8 x 7.41mm
Isolated fixed-ratio
Input: 0 – 60V
Output: 0 – 55V
Current: Up to 130A
Peak efficiency: 97%
As small as 22.83 x 8.52 x 4.9mm
Application examples
High performance computing
Vicor vertical power delivery improves performance and simplifies motherboard design. It enables processors to achieve previously unattainable performance levels necessary to fulfill the promise of high-performance applications such as Artificial Intelligence.
Automotive
Vicor DCM and PRM regulators and NBM fixed-ratio converter – when used alone or in combinations – support more than 300 configurations providing system designers with the keys to deploying the right power to each point-of-load within a 48V zonal architecture.
ATE
Vicor power modules' inherently low noise contributes to fully achieving inspection requirements. Their low profile simplifies thermal management, which in turn simplifies the mechanical design of inspection systems, allowing for maximum throughput in the same floorspace.
