DUBLIN, Calif., March 10, 2026 /PRNewswire/ — Amber Semiconductor, a fabless semiconductor company focused on advanced power management solutions for AI data centers, has announced the initial closing of its $30 million Series C financing round. This funding comes from both new and existing investors, aimed at scaling product development, expanding customer engagements, and accelerating the commercialization of its innovative vertical power delivery solutions.
Amber is at the forefront of developing new power architectures that aim to transform power delivery within data centers designed for artificial intelligence. Their proprietary PowerTile™ technology enables power delivery through a vertical path, allowing for backside placement on server boards. This design reduces power distribution losses to processors by over 85%, addressing vital challenges in power scalability, thermal management, and space constraints that are increasingly critical in modern AI environments.
“AI data centers are entering a new era where power delivery is becoming a key performance differentiator,” stated Thar Casey, Founder and CEO of Amber Semiconductor. “This financing marks an important milestone as we continue to execute on our vision of transforming power delivery for AI. The strong support from our investors reflects growing confidence in our technology and the critical role it will play in enabling the next generation of AI computing.”
This announcement follows Amber’s successful tape-out of its PowerTile™ vertical power delivery solution, which was completed in January 2026. By utilizing a vertical power delivery method instead of traditional lateral approaches, Amber’s technology enhances both efficiency and scalability for AI systems. The company anticipates beginning shipments to major customers in the third quarter of 2026.
In addition to its product developments, Amber Semiconductor will be leading a session at the Applied Power Electronics Conference (APEC) 2026 later this month, titled “Vertical Power for AI Data Centers.” The session will feature representatives from major industry players including AMD, Nvidia, and Global Foundries. This gathering is set to explore emerging trends, system-level innovations, and the increasing significance of vertical power architectures in shaping the future of AI infrastructure.
Founded in Silicon Valley, Amber Semiconductor focuses on delivering advanced power management solutions specifically tailored for AI data centers and related applications. Its PowerTile™ technology is distinguished by its ability to provide unprecedented power density and efficiency to high-performance processors, such as those used in AI, servers, and FPGAs, particularly in environments where space is limited.
With a portfolio of over 50 U.S. patents, Amber is a member of the Global Semiconductor Alliance (GSA) and has been recognized for its technological impact. The company has received accolades including Fast Company‘s Next Big Thing in Tech and consecutive Edison Awards for Innovation, as well as inclusion in EE Times‘ 100 Startups Worth Watching.
As the demand for efficient power delivery escalates with the growth of AI workloads, Amber Semiconductor’s innovations in power management may play a pivotal role in the evolution of data center infrastructure. The company is poised to become a key player in ensuring that AI data centers can operate efficiently and effectively in the face of increasing computational demands.
