Navitas Partners with Great Wall for Next Generation 400V-DC Power Architecture for AI Data Centers
GaNSense™ technology boosts 8x power for AI data centers, telecommunications, and industrial equipment in ultra-high power density DC-DC converters
TORRANCE, Calif., April 03, 2025 (GLOBE NEWSWIRE) -- (Nasdaq: NVTS), the only pure-play, next-generation power semiconductor company and industry leader in gallium nitride (GaN) power ICs and silicon carbide (SiC) technology, has announced its GaNSense power ICs will power GreatWall’s latest 2.5kW ultra-high power density DC-DC converter for AI data centers.
The rapid development of AI has imposed higher requirements for computing power on data centers. To accommodate more GPUs for computing, the architecture of 400V independent cabinets will become a new development trend. Module power supplies with small size, high efficiency, and greater independence will free up valuable cabinet space, directly enhance computing power, reduce energy consumption, and contribute to achieving dual-carbon goals.
has developed an industry-leading 2.5kW DC-DC converter in 1/4 brick outline with the world’s highest power density of 92.36W/cm³, up to 8 times higher than the output power of traditional silicon designs. With a record half-load efficiency of 97.9% and a wide input range of 320-420 VDC, this solution achieves the increasingly stringent efficiency guidelines and regulations from (OCP) and can be widely used in applications from AI data centers, telecommunications, and industrial equipment.
This ultra-high power density DC-DC converter is powered by Navitas’ GaNSense . The 650V, 45 mΩ, delivers 50% more power than prior designs, in an industry-standard, low-profile, low-inductance, 8 x 8 mm PQFN package for high-efficiency, high-density power systems. GaNFast power ICs with GaNSense technology feature GaN-industry-first features such as loss-less current sensing and the world’s fastest short-circuit protection, with a ‘detect-to-protect’ speed of only 30 ns, 6x faster than discrete solutions.
Unlike competing solutions, NV6169 is rated at 650V for nominal operation plus an 800 V peak-rating for robust operation during transient events. As a truly integrated power IC, the GaN gate is fully-protected and the whole device rated at an industry-leading electrostatic-discharge (ESD) specification of 2 kV.
"With its faster switching frequency and higher efficiency, 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,” said Michael Zhang, head of DC Product Line at Greatwall Power. “We look forward to deepening our collaboration with Navitas to unlock the application of GaN in more fields, continuously improve power supply efficiency to reduce energy consumption, and accelerate the low-carbon transformation of various industries."
"Navitas is deeply honored to cooperate with Great Wall Power to successfully create this ultra-high-power density 2.5 kW DC-DC converter. The profound heritage and innovative strength of Great Wall Power in the power supply field have enabled our GaNFast power ICs to fully demonstrate their advantages,’ said Charles Zha, SVP and GM of Navitas Asia-Pacific. “Navitas firmly believes that continuous cooperation with Great Wall will make GaN technology shine in multiple fields such as AI data centers and telecommunications and promote the industry to develop towards a more efficient and environmentally friendly direction."
