What Happened
Infineon Technologies has announced the acquisition of C2i Semiconductors, a Bangalore-based company that develops software-defined multiphase controllers and smart power stages for AI data center applications. The transaction is expected to close in the third quarter of calendar year 2026. The acquisition aims to strengthen Infineon's leadership in power solutions for AI data centers and accelerate software-defined power architectures from grid to core.
The deal expands Infineon's engineering capabilities in India and reinforces the country's role as a strategic innovation hub. Infineon says C2i's technology complements its existing portfolio of power semiconductors and power systems, enabling intelligent and scalable power delivery for AI servers and high-performance computing platforms. It also strengthens Infineon's top position in AI data center power solutions.

Software-defined power solutions combine advanced power semiconductors with intelligent digital control and software algorithms to optimize power conversion, regulation and system performance in real time. Because AI processors create highly dynamic power demands, power delivery systems must respond quickly to load fluctuations while maintaining efficiency and stability. Infineon says adding intelligence helps data center operators improve efficiency, reduce power losses, and support the increasing power density requirements of next-generation AI processors. Infineon's portfolio includes silicon, silicon carbide (SiC) and gallium nitride (GaN) technologies, as well as vertical power delivery solutions.
Previously from Infineon Technologies AG
Infineon has been expanding its AI data center power business, having signed a memorandum of understanding with LS ELECTRIC in July 2026 to jointly develop high-efficiency DC power infrastructure for AI data centers and next-generation power grids. The C2i acquisition continues that push by bringing digital power control technology in-house.

Why this matters
AI data centers consume massive and fast-varying power, and this acquisition adds software-defined control to make power delivery more efficient and stable. It strengthens Infineon's position in the AI infrastructure market and expands its engineering presence in India. Data center operators and chipmakers could benefit from more scalable power architectures.
