The global ecosystem of semiconductors, computing, and data centers is facing a significant physical challenge in the form of AI power delivery bottleneck. With the development of AI accelerators, HPC processors, and sovereign AI systems towards megawatts of power consumption per processor, the conventional methods of power delivery face certain physical limitations. AI silicon needs huge currents at voltages less than one, making power delivery and transient power load management a challenging engineering problem.
Traditional power management for enterprise servers used discrete multi-phase voltage regulator modules (VRMs) placed near the processors on the circuit board.
However, delivering thousands of amps through the circuit board traces would lead to parasitic resistances and serious thermal management issues.
With the advent of sub-2nm processors experiencing large load transients, power management components use up valuable space, creating power losses and heat issues.
Such power conversion inefficiencies lower overall compute efficiencies, reduce rack densities, and increase operating expenses for AI hyperscalers.
To overcome these constraints, semiconductor architects require Integrated Voltage Regulator (IVR) technology capable of moving voltage conversion directly into the processor package or substrate.
Addressing this high-consequence power challenge, intelligent power and sensing semiconductor leader onsemi announced an agreement to acquire Ferric, Inc. for up to $775 million-comprising $600 million in cash at closing and up to $175 million in milestone considerations.
By combining Ferric’s Integrated Voltage Regulator (IVR) technology and thin-film magnetics with onsemi’s power semiconductor portfolio, the acquisition establishes an end-to-end grid-to-core architecture to power next-generation AI processors.
Integrating Substrate-Level Voltage Regulation and Raising AI Targets
The acquisition bridges silicon-level power conversion with hyperscale AI hardware infrastructure. Ferric brings more than a decade of specialized engineering expertise, over 40 patents in integrated magnetics, and approximately 50 engineers across New York and Silicon Valley into onsemi’s organization. Supported by the transaction, onsemi raised its 2030 AI data center revenue target by $500 million to greater than $3 billion.
Key technical and operational pillars of the acquisition include:
Package-Level Power Conversion: Shifts voltage regulation from external boards into the processor substrate, slashing board real estate requirements by 50% to 70%.
Patented Thin-Film Magnetics Integration: Combines power controllers, FETs, inductors, and capacitors within a compact package to maximize energy density.
Superior Transient Response and Efficiency: Delivers immediate dynamic voltage scaling and sub-microsecond transient response, enabling AI chips to maximize tokens per watt.

Expanded AI Revenue Milestones: Raises onsemi’s 2030 AI data center revenue target to over $3 billion, with closing scheduled by the end of 2026.
“The rapid growth of AI is reshaping the requirements for power delivery to increasingly capable processors,” stated Hassane El-Khoury, President and CEO of onsemi.
Impact on the Semiconductors Industry
The acquisition of Ferric by onsemi signals major developments across the broader Semiconductors landscape:
1. Shifting to In-Package Integrated Regulation
For decades, power management was treated as a peripheral board-level design task decoupled from central processor silicon. onsemi’s move formalizes the semiconductor industry shift toward Co-Packaged In-Substrate Power Delivery. Delivering power at fractional voltages directly beside or underneath logic dies reduces resistance losses, making advanced packaging and power co-design mandatory for next-generation AI processors.
2. Establishing Grid-to-Core Co-Design as a Competitive Moat
Today’s hyperscalers and semiconductors consider semiconductor providers in terms of a full power delivery chain as opposed to individual components. The integration of utility-scale power switching with in-core IVRs is an indication that Holistic Grid-to-Core Control Is Necessary for Data Center Scale. Semiconductor companies that provide end-to-end silicon from high-voltage input through to micro-regulation in-package have more business clout.
Total Impact on Companies Doing Business in the Industry
The acquisition by onsemi brings about definite benefits for fabless semiconductors, server OEMs, and cloud hyperscalers:
Utilization of Silicon Compute Real Estate: The freeing up of circuit board space allows for the placement of more memory chips and optical interconnections inside compute racks.
Reduced Hyperscaler Operational Costs: Lowering of power conversion losses in the enormous server farms translates to reduced energy usage and cooling costs.
Accelerating AI Processor Innovation: Pre-integrated IVR silicon allows processor startups and chipmakers to design high-current processors without engineering complex external power loops.
Conclusion
onsemi’s acquisition of Ferric represents a pivotal milestone in the evolution of power electronics, advanced semiconductor packaging, and AI infrastructure. By uniting onsemi’s manufacturing scale and high-voltage power portfolio with Ferric’s substrate-level IVR architecture, onsemi delivers a comprehensive blueprint for next-generation computing. For the global semiconductor industry, this transaction confirms that overcoming the AI compute wall requires innovating at the intersection of advanced silicon packaging, magnetic materials, and integrated power delivery.
