Navitas Semiconductor has announced the world’s first 8.5 kW power supply unit (PSU), powered by GaN and SiC technologies to achieve 98% efficiency, for next-generation AI and hyperscale data centers.
The AI-optimized 54V output PSU complies with Open Compute Project (OCP) and Open Rack v3 (ORv3) specifications and utilizes high-power GaNSafe and Gen-3 Fast SiC MOSFETs configured in 3-phase interleaved PFC and LLC topologies, to ensure the highest efficiency and performance, with lowest component count. The PSU’s shift to a 3-phase topology for both the PFC and LLC (vs. 2-phase topologies used by competing PSUs) enables the industry’s lowest ripple current and EMI.
Furthermore, the PSU reduces the number of GaN and SiC devices by 25% compared with the nearest competing system, which reduces the overall cost. The PSU has an input voltage range of 180 to 264 Vac, a standby output voltage of 12 V, and an operating temperature range of -5oC to 45oC. Its hold-up time at 8.5 kW is 10 ms, with 20 ms possible through an extender.
The 3-Phase LLC topology is enabled by high-power GaNSafe, which is specifically created for demanding, high-power applications, such as AI data centers and industrial markets. Navitas’ 4th generation integrates control, drive, sensing, and critical protection features that enable unprecedented reliability and robustness. GaNSafe is the world’s safest GaN with short-circuit protection (350ns max latency), 2kV ESD protection on all pins, elimination of negative gate drive, and programmable slew rate control. All these features are controlled with 4-pins, allowing the package to be treated like a discrete GaN FET, requiring no VCC pin. Suitable for applications from 1 kW to 22 kW, 650 V GaNSafe in TOLL and TOLT packages are available with a range of RDS(ON)MAX from 25 to 98 mΩ.
The 3-Phase interleaved CCM TP-PFC is powered by Gen-3 Fast SiC MOSFETs with ‘trench-assisted planar’ technology, which has been enabled by over 20 years of SiC innovation leadership and offers world-leading performance over temperature, delivering cool-running, fast-switching, and superior robustness to support faster charging EVs and up to 3x more powerful AI data centers.
“This complete wide bandgap solution of GaN and SiC enables the continuation of Navitas’ AI power roadmap which enables this 8.5kW and plans to drive to 12kW & higher in the near-term”, said Gene Sheridan, CEO and co-founder of Navitas. “As many as 95% of the world’s data centers cannot support the power demands of servers running NVIDIA’s latest Blackwell GPUs, highlighting a readiness gap in the ecosystem. This PSU design directly addresses these challenges for AI and hyperscale data centers.”
The PSU will be on display for the first time at Electronica 2024 (Hall C 3, booth 129, November 12th– 15th).

STMicroelectronics inaugurated its new design and industrialization center, equipped with a test lab, in Pisa Montacchiello, Italy. The CEO of STMicroelectronics Italy, Lucio Colombo, and the Rector of the University of Pisa, Riccardo Zucchi, cut the ribbon of the new center, the thirteenth ST site in Italy and the first in Tuscany.
The center, built in collaboration with professors from the University of Pisa’s Department of Information Engineering, currently houses around 40 people mainly dedicated to the design and industrialization of integrated circuits. They include analog and digital designers with different skills, together with researchers and thesis students from the University of Pisa.
Most of the designers belong to ST’s APMS Product Group’s Analog Custom Devices (ACD) division, which works on the design and development of products for the consumer electronics market. In particular, the Pisa team of the ACD division focuses on products for wireless charging and power management. Their goal is to identify and implement innovative solutions to improve the efficiency of battery-powered devices like smartphones. The center is equipped with a test lab to carry out the validation and industrialization of the products developed on-site.
In addition to inaugurating and visiting the center, Riccardo Zucchi and Lucio Colombo signed a framework agreement, the purpose of which is to – support the training of qualified students and graduates by collaborating on teaching courses for the University and by setting up scholarships in line with current regulations;
– contribute to studies and research focused on technological innovation within the center’s areas of expertise and interest;
– to uphold the high cultural standards of its operators and promote their professional development through meaningful contacts and cooperation with the University through courses guaranteed by the University.“The Pisa Center was born 20 months ago with the aim of growing quickly by acquiring talent in the area, thanks to the collaboration with the University of Pisa, but also by attracting talent eager to return to Tuscany in search of the job opportunities offered by a global leader,” said Lucio Colombo, CEO of STMicroelectronics Italy. “This is a model that ST has applied over the years at Italian universities close to its research and production centers.”
“The goal was to reach around 40 employees in two years and to date we are satisfied with the progress made. The Center relies on electronics engineers with mixed skills: analog/digital/software and testing, and with different seniority, together with researchers and thesis students,” explains Patrizia Milazzo, ACD Director, STMicroelectronics. “We believe that the rapid development of the center was made possible through the great collaboration with the University and the determination of ST colleagues, who were strongly dedicated to creating a center of excellence in Tuscany.”
