Infineon Joins NVIDIA MGX AI Factory Ecosystem to Advance Next-Generation AI Data Center Power Architecture

Infineon Technologies AG has officially joined the NVIDIA MGX Ecosystem to help accelerate the power transformation of next-generation AI data centers. Announced on May 29, 2026, the collaboration positions Infineon’s advanced power management technologies as a key enabler of NVIDIA’s MGX™ architecture and emerging 800VDC power infrastructure designed for the AI factory era.

The open and modular MGX reference architecture is built to support the growing demands of agentic AI workloads. By integrating 800VDC-compatible power racks, existing AI infrastructure can increase computing density and performance while also creating a scalable upgrade path for future high-power AI deployments.

According to Adam White, Infineon’s partnership with NVIDIA focuses on redefining power delivery across the entire chain — from the electrical grid all the way to the processor core — which is becoming increasingly important for the next wave of AI innovation.

He noted that as AI models continue to grow in size and complexity, data centers must deliver significantly higher compute performance while operating within the same physical space, power, and thermal constraints. By combining Infineon’s power technologies with NVIDIA’s modular MGX platform, the companies aim to improve energy efficiency throughout the entire data center power conversion process.

Infineon brings extensive expertise in power conversion technologies spanning the complete power path, utilizing multiple semiconductor materials including silicon (Si), silicon carbide (SiC), and gallium nitride (GaN). This broad technology portfolio is expected to accelerate the industry’s transition toward full-scale 800VDC architectures.

The company’s GaN solutions are capable of delivering highly efficient and extremely compact bus converter performance at switching frequencies approaching 1MHz. In addition, Infineon’s proprietary SiC JFET technology, combined with dedicated controller ICs, is designed to support the protection and hot-swap requirements of native 800V server motherboards.

Infineon’s power management systems are capable of converting 800V power rails down to intermediate voltages such as 50V, 12V, and even as low as 6V, enabling more efficient power delivery throughout AI infrastructure.

As part of the NVIDIA MGX AI Factory ecosystem, Infineon supports complete 800VDC power conversion workflows for MGX-based systems. By reducing the number of power conversion stages and bringing DC power distribution closer to the rack level, the architecture improves overall efficiency, simplifies infrastructure design, and enables higher-density AI deployments for future data centers.
