ADI to Acquire IVR Tech to Join Data Center’s Power Gold Rush

2026-05-19 · Source: Big Data & AI News - EE Times · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Cloud Computing & IT Infrastructure, AI Hardware · Depth: Intermediate, short

Summary

Analog Devices Inc. (ADI) is reportedly acquiring Empower Semiconductor for \$1.5 billion, a startup specializing in integrated voltage regulators (IVRs) designed for direct placement within AI processor packages. Empower's IVRs offer on-demand, scalable power with the speed, precision, and signal integrity crucial for AI processors, addressing critical data center power consumption limits. These digitally configurable devices integrate multiple power supplies into a single IC, eliminating discrete components like magnetic parts and multi-layer ceramic capacitors, resulting in a package three to five times smaller than typical power delivery systems. This acquisition allows ADI to gain advanced power delivery solutions for GPUs and AI accelerators, an area where its existing portfolio, accumulated through Linear Technology and Maxim Integrated acquisitions, falls short. The move highlights the increasing importance of power semiconductors in AI compute infrastructure, alongside advanced packaging and high-bandwidth memory.

Key takeaway

For AI Architects designing next-generation compute infrastructure, you must prioritize integrated power delivery solutions. Empower Semiconductor's IVR technology, now part of ADI, demonstrates that on-package voltage regulation is critical for managing power density and efficiency in AI accelerators. Evaluate compact IVR solutions to significantly reduce system footprint, enhance transient response, and lower your data center's total cost of ownership. This shift is as vital as advanced packaging and HBM for future AI performance.
