onsemi's Power Solutions Supporting Next-Generation AI Factories

As hyperscalers and enterprise operators compete to build more powerful AI infrastructure, power supply and energy efficiency have become the biggest challenges. According to industry analyst forecasts, AI rack power requirements are expected to exceed 1MW per rack in the near future.

Against this backdrop, onsemi is strengthening its efforts within the NVIDIA MGX™ ecosystem, supplying advanced power systems designed to support next-generation AI data centers and accelerated computing platforms.

NVIDIA MGX's modular building block architecture allows OEMs and system builders to configure, deploy, and scale AI infrastructure more quickly while reducing development complexity and time-to-market. onsemi provides technology that supports all stages of power conversion within the MGX ecosystem.

onsemi's broad portfolio, covering the entire power tree, strongly supports the flexibility of free combination that is the essence of the MGX ecosystem. onsemi's in-house manufacturing capabilities and expertise in silicon, silicon carbide, and gallium nitride technologies also provide supply chain resilience as the global deployment of AI infrastructure accelerates.

onsemi's technology already supports existing MGX systems, with adoption expanding in areas such as power field-effect transistors (FETs), multi-phase power solutions, silicon carbide (SiC) JFETs, and gallium nitride (GaN) technology. This collaboration is expected to extend to next-generation 800VDC power architectures being developed for increasingly compute-dense AI environments.

Sudhir Gopalswamy, Group President of the Intelligent Sensing and Analog & Mixed Signal Group at onsemi, stated: "With the explosive adoption of AI, agentic AI, and the advancement of inference, AI compute is growing exponentially, driving a sharp increase in demands for power delivery, cooling, and infrastructure efficiency. Emerging high-voltage architectures like the new 800VDC design are essential for scaling AI infrastructure. They improve efficiency and increase power density to over 1MW per rack while reducing deployment cost and complexity."

Solving One of the Biggest Bottlenecks in AI Infrastructure

onsemi's role in the MGX ecosystem is to solve one of the most pressing bottlenecks in AI infrastructure: how to deliver more power more efficiently to increasingly dense compute environments.

onsemi enables the modularity characteristic of MGX systems by directly providing power solutions to NVIDIA and MGX ecosystem partners, from power supply unit (PSU) and battery backup unit (BBU) providers to 800 VDC PDB suppliers.

Why Power Efficiency Matters in the AI Economy

There is a growing recognition among industry analysts that power supply is one of the defining constraints of the AI era. As GPU clusters scale from individual servers to racks and entire data centers, even marginal efficiency improvements can lead to significant reductions in operational costs and energy consumption.

onsemi plays a critical role in the NVIDIA MGX ecosystem as a power semiconductor manufacturer with technical expertise across multiple technologies capable of addressing increasingly complex architectures.

Beyond the Data Center

The impact extends beyond today's AI data centers. The same power architectures being developed for AI factories are expected to influence next-generation designs in automotive and industrial sectors, markets where efficiency, thermal management, and system reliability are paramount.

In this sense, the collaboration with NVIDIA MGX demonstrates onsemi's expertise and comprehensive power product portfolio supporting the foundational infrastructure layer of the AI economy itself.

As the race to build next-generation AI factories intensifies, power efficiency may become as critical as processing power. onsemi is well-positioned to meet these needs with both technological capabilities and in-house production capacity.
