The company said that it was looking at a 3x power increase in order to support similar exponential growth in AI power demands expected over the next 12-18 months.
Traditional CPUs require typically only 300W and the data centre ac/dc power supplies would typically power the equivalent of 10 of these or 3,000W (3kW).
However, high-performance AI processors like NVIDIA’s ‘Grace Hopper’ H100 are already demanding 700W each, with next-gen ‘Blackwell’ B100 & B200 chips anticipated to increase to 1,000W or more by next year.
To meet this exponential power increase, Navitas is now developing server power platforms which rapidly increase from 3kW to up to 10kW. In August 2023, Navitas introduced a 3.2kW data centre power platform that utilised the latest GaN technology enabling over 100W/in3 and over 96.5% efficiency. Now, Navitas is releasing a 4.5kW platform enabled by a combination of GaN and SiC to push densities over 130W/in3 and efficiencies over 97%.
According to Navitas, these two platforms have already generated significant market interest with over 20 data centre customer projects in development.
Navitas has now announced plans to introduce an 8-10kW power platform by the end of 2024 to support 2025 AI power requirements. The platform will use newer GaN and SiC technologies and further advances in architecture to set all-new industry standards in power density, efficiency and time-to-market.
Navitas said that it was already engaged with major data-centre customers, with full platform launch anticipated in Q4 ’24, completing this 3x increase in power demands in only 12-18 months.
Navitas’ design centre is creating these system designs to address the dramatic increases in AI data centre power requirements and help customers to deploy platforms quickly and effectively to meet the accelerated time-to-market demands of rapid AI advances.
System designs include complete design collateral with fully-tested hardware, schematics, bill-of-materials, layout, simulation and hardware test results to maximize first-time-right designs and fast revenue generation.
“The rapid development and deployment of artificial intelligence (AI) into global data centre has created a dramatic and unexpected power challenge for our entire industry,” noted Gene Sheridan, Navitas’ CEO and Co-Founder. “Our investment in leading-edge GaN and SiC technologies, combined with our unique design centre capabilities, have positioned us well.”
