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. As increasingly powerful AI processors create highly dynamic and rapidly changing power demands, power delivery systems must respond faster and more precisely to sudden load fluctuations while maintaining efficiency and system stability. By adding intelligence to the power delivery architecture, software-defined solutions can help improve efficiency, reduce power losses and support the increasing power density requirements of next-generation AI processors.
The acquisition combines C2i Semiconductors' digital power expertise with Infineon's global scale, application know-how and broad portfolio of power semiconductors, including silicon, silicon carbide (SiC) and gallium nitride (GaN) technologies, as well as vertical power delivery solutions. Together, the teams will accelerate development of more intelligent, efficient and scalable power delivery solutions for AI infrastructure, including future Substrate Integrated Voltage Regulators (SIVR). Infineon says the combination strengthens its capabilities across the entire power path from grid to core.

Across multiple locations in India, a footprint the acquisition further expands
The acquisition adds highly specialized engineering expertise to Infineon's global R&D network and further strengthens its innovation capabilities in India. The combined team will contribute to reinforcing Bengaluru's role as an important innovation location for digital power technologies and to accelerating development of next-generation power solutions for AI infrastructure.
Previously from Infineon Technologies AG
In August 2026, Infineon announced it was acquiring Bangalore-based C2i Semiconductors to add digital power control technology for AI data centers, with the deal expected to close in Q3 2026; today's story marks that completion. Earlier, in July 2026, Infineon and LS ELECTRIC signed an MoU to jointly develop high-efficiency DC power infrastructure for AI data centers and next-generation power grids, part of the same push into data center power.

Why this matters
The deal shows how the AI boom is reshaping the chip supply chain: as AI processors demand faster and more precise power delivery, chipmakers are buying up specialist digital power expertise. Infineon's roughly 2,800 employees in India and the Bengaluru engineering team are directly affected, and the company says the acquisition reinforces India's role as a strategic innovation hub. Buyers of AI servers and high-performance computing platforms are the intended beneficiaries of the more efficient power architectures the combined teams aim to build.
