Analog Devices completed its $1.5 billion acquisition of Empower Semiconductor, adding integrated voltage regulators and silicon capacitors designed for high-density AI processors and data center systems. ADI announced the all-cash transaction in May 2026 and closed it on July 7, expanding its power-management portfolio from facility-level infrastructure to point-of-load delivery near AI accelerators.
Empower’s technology addresses the final stages of power delivery, where voltage regulators must supply rapidly changing currents to kilowatt-class GPUs, XPUs and custom AI processors. Its Crescendo platform positions voltage regulation directly beneath the processor to shorten electrical paths and improve transient response. Empower also develops integrated voltage regulators for multi-domain chiplet designs, E-CAP silicon capacitors and the FinFast power platform, which combines FinFET-based power circuits, advanced packaging, magnetics and silicon capacitors.
ADI plans to combine these technologies with its existing power conversion, monitoring, control and protection portfolio. The acquisition supports ADI’s “grid-to-core” strategy, spanning power entering the data center through rack-level conversion and distribution to the tightly regulated voltages required by processors. ADI reported more than $11 billion in fiscal 2025 revenue, while its data center revenue increased by more than 90% year over year during fiscal Q2 2026.
• Transaction value: Approximately $1.5 billion in cash
• Closing date: July 7, 2026
• Acquired company: Empower Semiconductor, based in Milpitas, California
• Core technologies: Integrated voltage regulators, silicon capacitors, vertical power delivery and advanced power packaging
• Crescendo architecture: Places high-density voltage regulation directly beneath kilowatt-class processors
• E-CAP technology: Silicon capacitors with low equivalent series resistance and inductance, wideband performance up to 10 GHz and no stated voltage, temperature or aging derating
• IVR portfolio: Multi-domain integrated regulators supporting power levels up to 25 W for SoCs and chiplet-based systems
• Target markets: AI accelerators, data centers, networking equipment and other power-constrained electronic systems
“AI infrastructure is fundamentally reshaping how power must be delivered, with energy now one of the most persistent constraints to scaling next-generation systems,” said Vincent Roche, CEO and Chair of Analog Devices. “Leveraging ADI’s technology and scale, we will help customers rearchitect their power systems and achieve the compute densities next-generation AI demands.”
🌐 Analysis: The acquisition moves ADI closer to the processor package, where rising accelerator current, fast load transients and voltage drops increasingly affect AI system performance. It also reflects a broader shift in AI infrastructure toward vertically integrated power architectures that coordinate facility, rack, board, package and die-level power delivery.
