Amber Semiconductor announced a groundbreaking advancement in power management technology. At the 2025 Applied Power Electronics Conference (APEC), AmberSemi will demonstrate a new 50VDC to 0.8VDC solution designed to significantly enhance power efficiency and density for AI chips in data centers.
This innovative solution eliminates conversion steps and reduces size, enabling direct 50VDC to 0.8VDC power delivery to AI chips on data center server motherboards, scalable to 1500A+. Developed in response to requirements from top data center operators and major solution providers, AmberSemi's DC-DC conversion technology aims to improve power utilization, facilitating faster AI computing scalability.
AmberSemi's solution is projected to increase efficiency from the current 81% to over 90%, representing a 47% improvement. This efficiency gain translates to an estimated $4 billion annual savings and a reduction of nearly 15 million tons of CO2 emissions in the U.S. alone.
"There is a new energy crisis in data centers, driven by the power demands of AI processing," said Thar Casey, CEO of AmberSemi.
"Our 50VDC to 0.8VDC solution addresses this challenge by improving overall system architecture, enhancing efficiency, and supporting the power needs of AI innovations."
Exacerbating this problem is that data centers are built on the same inefficient power architectures that are struggling to support the power needs of new innovations like AI. With AI driving complex computations with lower process nodes following Moore’s Law, the problem is not going away. Rack power is continuing to increase from 10-40kW to 100-200kW in a short period of time.
“We are pioneering new solutions for improved power transmission, including 800VDC architectures and 48V/50V intermediate bus voltages, ideal for factories, data centers and even automotive battery systems. This architecture upgrade will improve efficiency for large power systems and provide a better approach to power distribution and conversion steps,”
