onsemi collaborating with NVIDIA to accelerate transition to 800V power solutions for next-gen AI data centers
Intelligent power and sensing technology firm onsemi of Scottsdale, AZ, USA says that it is working with NVIDIA of Santa Clara, CA, USA to support the transition to 800V direct current (VDC) power architectures, which is driving significant gains in efficiency, density and sustainability for next-generation AI data centers.
At the core of this shift is a new power distribution system, which must distribute a massive amount of power with minimal losses during each voltage conversion. Onsemi says that its intelligent power portfolio is playing a critical role in enabling the next generation of AI data centers by delivering high-efficiency, high-density power conversion across every stage of the power journey — from high-voltage AC/DC conversion at the substation to precise voltage regulation at the processor level.
Leveraging decades of innovation in both silicon and silicon carbide (SiC) technologies, onsemi provides solutions for solid-state transformers, power supply units, 800VDC distribution, and core power delivery, all integrated with intelligent monitoring and control. onsemi reckons that this breadth and depth of capability makes it one of the few companies able to meet the demanding power requirements of modern AI infrastructure with scalable, physically realizable designs.
