Navitas Semiconductor (NVTS) has formed a strategic partnership with Great Wall Power to create a cutting-edge 2.5kW ultra-high power density DC-DC converter, specifically designed to serve AI data centers. Powered by Navitas’ GaNSense technology, the converter achieves an unmatched power density of 92.36W/cm³, delivering eight times the power of conventional silicon designs.
With a half-load efficiency of 97.9% and operating within a 320-420 VDC input range, the solution adheres to the stringent efficiency guidelines set forth by the Open Compute Project (OCP). The DC-DC converter utilizes Navitas' GaNSense NV6169, a 650V, 45 mΩ device, which provides 50% more power than previous designs. It features groundbreaking elements such as loss-less current sensing and rapid short-circuit protection, ensuring robust performance.
This collaboration between Navitas and Great Wall Power aims to propel 400V-DC power architecture forward, enhancing computing power while minimizing energy consumption. The advanced design is set to meet the demands of AI data centers, telecommunications, and industrial equipment, by focusing on reduced size, increased efficiency, and greater operational independence.
According to Michael Zhang, the head of the DC Product Line at Great Wall Power, "GaN has become a key factor in unlocking the next generation of power supplies. We are very pleased to collaborate with Navitas, an industry leader in GaN technology, and successfully enable this industry-leading ultra-high-power density and ultra-high efficiency DC-DC converter.”
The converter demonstrates the potential to free up valuable cabinet space, enhance computational capabilities, reduce energy usage, and support dual-carbon goals, marking a significant step towards more sustainable and efficient data center operations.
