Infineon Technologies AG has announced the completion of its acquisition of C2i Semiconductors, a Bengaluru-based technology company specializing in software-defined multiphase controllers and smart power stages for AI data center 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.

The acquisition further strengthens Infineon’s leadership in power solutions for AI data centers, expands its engineering capabilities in India and reinforces the country’s role as a strategic innovation hub. With the completion of the transaction, the C2i Semiconductors team becomes part of Infineon’s 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 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.
