Analog Devices, has made public a definitive agreement to acquire Empower Semiconductor in an all-cash deal of $1.5 billion, which will enlarge ADI’s portfolio of power delivery solutions with a very high power density, suitable for artificial intelligence and other systems with a heavy use of computing resources.
This acquisition is a part of a growth strategy as the AI infrastructure boom is creating more and more problems for power delivery architectures, where both power density and efficiency are turning into the main barriers to scaling new processors and improving the performance of data centers.
ADI said the combination will help address one of the industry’s most pressing technical challenges: delivering highly efficient power conversion directly at the point of compute while supporting rapidly fluctuating workloads required by AI systems.
By integrating Empower’s technologies into ADI’s power management portfolio, the companies aim to enable power conversion closer to processors, reducing power delivery path lengths and improving system efficiency, performance, and compute density.

“AI infrastructure is fundamentally reshaping how power must be delivered, with energy now the most persistent constraint to scaling next-generation systems,” said Vincent Roche. “ADI already delivers some of the highest-performance power management solutions in the industry, and with Empower we are further expanding our portfolio to help customers rearchitect their power systems and achieve the compute densities next-generation AI demands.”
The companies noted that the implications extend beyond AI data centers into other compute-intensive sectors where energy efficiency limits system performance, including communications, industrial applications, and advanced computing platforms.
Empower Semiconductor specializes in integrated voltage regulators (IVRs) and silicon capacitor technologies designed to improve power density, efficiency, and response times in advanced processors and AI hardware.
According to the announcement, Empower’s silicon capacitor technologies are already in production, while its IVR programs are being developed in collaboration with hyperscalers and AI silicon providers.
“Empower was founded to solve the hardest problem in AI power delivery – the power bottleneck that is limiting AI throughput,” said Tim Phillips. “Our technology enables the power density, speed and efficiency required by AI processors to reach their full potential, unleashing generations of performance improvements.”
ADI said it plans to accelerate Empower’s commercialization and adoption through its manufacturing scale, global operations, and customer relationships.
The transaction reflects the broader semiconductor industry focus on infrastructure technologies supporting AI workloads, where advancements in power delivery, thermal management, and system efficiency are becoming as strategically important as processor performance itself.
Once completed, the acquisition is expected to strengthen ADI’s position in system-level power management platforms spanning the full energy chain from grid infrastructure to processor-level compute systems.
