onsemi Expands NVIDIA MGX Collaboration to Power the Next Generation of AI Infrastructure
As the demand for AI-driven computing continues to surge, power delivery and energy efficiency have become critical challenges for data center operators worldwide. To address these growing requirements, onsemi is expanding its role within the NVIDIA MGX™ ecosystem, providing advanced power technologies designed to support next-generation AI data centers and accelerated computing platforms.
Industry forecasts suggest that AI server racks may soon require more than 1 megawatt of power per rack, creating unprecedented demands on power architectures. In response, onsemi is leveraging its expertise in power semiconductors to help enable scalable, efficient, and high-performance AI infrastructure.
Supporting the NVIDIA MGX Ecosystem
NVIDIA’s MGX modular architecture allows OEMs and system integrators to rapidly develop, deploy, and scale AI systems while reducing design complexity and accelerating time-to-market. onsemi contributes technologies that support every stage of power conversion throughout the MGX platform.
With a broad portfolio spanning silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) technologies, onsemi is well positioned to meet the flexible design requirements of AI infrastructure. The company’s vertically integrated manufacturing capabilities further strengthen supply chain resilience as global demand for AI computing continues to rise.
Today, onsemi technologies already power MGX-based systems through solutions including power FETs, multiphase power management products, SiC JFETs, and GaN devices. The collaboration is also expected to extend into emerging 800VDC power architectures, which are increasingly being considered for high-density AI computing environments.
Advancing High-Voltage AI Power Architectures
According to Sudhir Gopalswamy, President of onsemi’s Intelligent Sensing Group, the rapid growth of AI applications, agentic AI, and inference workloads is driving exponential increases in computational demand. As a result, requirements for power delivery, cooling, and infrastructure efficiency are becoming more significant than ever.
High-voltage power architectures, including emerging 800VDC systems, are viewed as a key enabler for scaling future AI infrastructure. These solutions can increase power density to 1MW per rack or beyond, while simultaneously improving efficiency and reducing deployment complexity and operational costs.
Addressing a Critical AI Infrastructure Challenge
One of the most pressing challenges facing the AI industry is efficiently delivering increasing amounts of power to ever-denser computing environments. onsemi’s role within the MGX ecosystem focuses on solving this challenge through advanced power management technologies.
The company supplies power solutions directly to NVIDIA and MGX ecosystem partners, including power supply unit (PSU) providers, battery backup unit (BBU) manufacturers, and 800VDC power distribution board suppliers. This support enables the modular and scalable deployment of MGX-based AI systems.
Why Power Efficiency Matters in the AI Era
As AI infrastructure expands from individual servers to rack-scale and data-center-scale deployments, even small improvements in power efficiency can generate significant reductions in energy consumption and operating expenses.
With extensive expertise in power semiconductors, onsemi plays a vital role in supporting increasingly sophisticated AI architectures. Its technology portfolio helps improve system efficiency while enabling higher computing densities and more sustainable operations.
Impact Beyond AI Data Centers
The innovations being developed for AI factories are expected to influence a wide range of future applications beyond data centers. Similar high-efficiency power architectures are likely to benefit automotive, industrial automation, and other mission-critical markets where thermal performance, reliability, and energy efficiency remain top priorities.
Through its expanding collaboration with NVIDIA MGX, onsemi continues to demonstrate its leadership in power solutions for the AI economy. As competition to build the next generation of AI factories intensifies, efficient power delivery is becoming just as important as processing performance—and onsemi is strategically positioned to help drive that transformation.
