Infineon Technologies has completed its acquisition of Bengaluru-based C2i Semiconductors, adding software-defined multiphase controllers and smart power stages to its portfolio for AI data centers. The deal gives Infineon deeper capabilities across power delivery systems as AI processors push server platforms toward higher power density and more volatile electrical loads. C2i’s technology complements Infineon’s power semiconductor portfolio and supports architectures designed to manage electricity from the grid through to the processor. The transaction also expands Infineon’s engineering base in India and brings the C2i team into its Power Systems division.

“Completing this acquisition marks an important milestone for our AI power business and our innovation activities in India,” said Adam White, President of Infineon’s Power Systems division. “C2i Semiconductors brings exceptional expertise in software-defined power management and system-level power architectures, backed by a highly experienced engineering team. By combining these capabilities with Infineon’s semiconductor technologies, application know-how, manufacturing capabilities and global customer reach, we will accelerate innovation in power delivery solutions for AI data centers and create significant value for our customers. I am delighted to welcome the C2i team to Infineon.”

Software-defined power moves closer to AI’s core

The acquisition targets a growing constraint inside AI infrastructure: delivering power quickly enough to increasingly demanding processors without sacrificing efficiency or stability. Software-defined power systems combine advanced semiconductors with digital controls and algorithms that can adjust power conversion and regulation as operating conditions change. AI workloads can create rapid swings in processor demand, requiring power delivery systems to respond to load fluctuations with greater speed and precision. By adding software intelligence to the electrical architecture, these systems can improve conversion efficiency, limit power losses and accommodate rising processor power density.

For Infineon, the strategic value extends beyond another controller or power-stage product. The company is combining C2i’s digital power expertise with silicon, silicon carbide and gallium nitride technologies, alongside its application knowledge, manufacturing footprint and global customer relationships. The combined portfolio spans vertical power delivery architectures and supports development of technologies such as future Substrate Integrated Voltage Regulators, or SIVRs. That positioning gives Infineon a broader role in the power path as AI servers evolve toward increasingly dense computing architectures.

Bengaluru becomes a bigger AI power hub

C2i brings expertise in software-defined power management, multiphase controllers, smart power stages, digital control and system-level power architectures. Those capabilities strengthen Infineon’s ability to address power delivery across the path from grid infrastructure to the processor, linking semiconductor components with increasingly complex server-level requirements. The combination also gives Infineon additional engineering capacity for AI servers and high-performance computing platforms. As a result, the acquisition could accelerate product development at a time when AI infrastructure operators are demanding higher efficiency and tighter control over power delivery.

Infineon also sees the transaction as an investment in its broader Indian engineering network. The combined teams will contribute to development work in Bengaluru and strengthen the city’s position in digital power technologies supporting next-generation AI infrastructure. Infineon currently employs approximately 2,800 people across multiple locations in India. The acquisition therefore adds a specialized power engineering capability to an existing local workforce while giving C2i access to Infineon’s global R&D and commercial infrastructure.

Power delivery becomes an AI infrastructure battleground

AI infrastructure investment has increasingly shifted attention from computing capacity toward the systems that keep processors operating reliably. Power delivery sits at the center of that challenge because faster accelerators, denser server configurations and increasingly dynamic workloads all place greater demands on electrical architectures. Infineon’s acquisition of C2i reflects that shift, combining semiconductor scale with software-controlled power management rather than treating power components as isolated hardware. The strategic objective is to build power systems capable of scaling alongside the next generation of AI computing.

The transaction also underscores the changing role of India in the global AI hardware supply chain. Infineon gains a Bengaluru-based engineering team with specialized digital power expertise, while India gains another link to the development of infrastructure technologies serving global AI demand. Meanwhile, the focus on power management shows how competition in AI infrastructure is moving deeper into the electrical layers beneath the processor. Ultimately, the acquisition positions Infineon to pursue a larger share of the power architecture that will determine how efficiently future AI data centers convert electricity into computing capacity.
