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
Solving the toughest power delivery challenges
Solving the toughest power delivery challenges
To enable the highest performance in hyperscale data centers, we are changing the way GPU and AI processors are powered with our factorized power on package architecture. When board real estate and system weight is a business and engineering obstacle, we redefine the power density limitations of 3-phase AC, HVDC and 48V power distribution solutions, in automotive, industrial and defense markets. Solving the toughest power delivery challenges and enabling a competitive advantage for our customers can only be achieved if we stay on the forefront of power architectures, conversion topologies and packaging technology.
