Infineon has agreed to acquire C2i Semiconductors, a Bangalore-based company focused on software-defined multiphase controllers and smart power stages for AI data center applications. Infineon says the deal is aimed at strengthening its power management portfolio for AI servers and high-performance computing platforms, with particular emphasis on “grid-to-core” power delivery architectures.
C2i Semiconductors brings expertise in intelligent digital power management, multiphase controllers, and system-level power architectures, including vertical power delivery approaches and Substrate Integrated Voltage Regulators (SIVR). Infineon says C2i’s work complements its existing power semiconductor and power systems portfolio, which includes silicon, silicon carbide (SiC), and gallium nitride (GaN) technologies.
For data center engineers, the practical issue is that modern AI processors can present fast, large load transients that stress the power delivery network. Digital control and software algorithms in the power stack are one way to tune response and stability while trying to preserve conversion efficiency. Vertical power delivery and regulator placement closer to the load are also increasingly discussed in the context of reducing distribution losses and managing tighter voltage margins, but execution details matter a lot at board and platform level.
Adam White, President of Infineon’s Power Systems (PS) division, said the acquisition will “create a new center of excellence for digital power technologies in India” and help Infineon “accelerate innovation” in next-generation vertical power delivery architectures. Ram Anant, Founder and CEO of C2i Semiconductors, said joining Infineon will provide access to “semiconductor technologies, manufacturing capabilities, and global customer relationships” to bring C2i’s software-defined power architectures to customers worldwide.
The transaction is expected to close in the third quarter of calendar year 2026. Infineon said the deal expands its innovation footprint in India; the company reports it employs approximately 2,800 people in the country.
