Infineon completes acquisition of C2i Semiconductors to expand innovation capabilities in AI data centre power management solutions
Infineon has announced the completion of its acquisition of C2i Semiconductors, a Bengaluru-based technology company specialising in software-defined multiphase controllers and smart power stages for AI data centre applications. C2i Semiconductors’ technology complements Infineon’s portfolio of power semiconductors and power systems, enabling intelligent and scalable power delivery architectures from grid to core for AI servers and high-performance computing platforms. With the completion of the transaction, the C2i Semiconductors team becomes part of Infineon’s Power Systems division.
Software-defined power solutions combine advanced power semiconductors with intelligent digital control and software algorithms to optimise 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.
Together, the teams will accelerate the development of more intelligent, efficient and scalable power delivery solutions for AI infrastructure, including future Substrate Integrated Voltage Regulators (SIVR).
C2i Semiconductors adds expertise in software-defined power management, multiphase controllers, smart power stages, digital control technologies and system-level power architectures. The combination strengthens Infineon’s capabilities across the entire power path from grid to core and supports the development of next-generation power solutions for AI servers and high-performance computing platforms.
The acquisition also adds highly specialised 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 the development of next-generation power solutions for AI infrastructure. Infineon currently employs approximately 2,800 people across multiple locations in India.
