Infineon completes acquisition of C2i Semiconductors to strengthen its portfolio of power management solutions for AI data centers.
Infineon Technologies has completed its acquisition of Bengaluru-based C2i Semiconductors, bringing the Indian semiconductor company's software-defined power technology into Infineon's Power Systems division.
The transaction, originally announced in August, adds C2i's expertise in software-defined multiphase controllers, smart power stages and system-level power architectures to Infineon's existing power semiconductor portfolio. Infineon said the combination aims to strengthen its ability to develop power-delivery solutions for AI data centres, servers and high-performance computing platforms.
This acquisition carries significance beyond a conventional semiconductor deal. Infineon and C2i address complementary parts of the AI infrastructure stack: Infineon provides established power semiconductor technologies, manufacturing capabilities and global customer reach, while C2i contributes digital control and system-level expertise for managing increasingly dynamic processor power requirements. The C2i team has now joined Infineon's Power Systems division.
Modern AI processors create rapidly changing and highly concentrated power demands. As accelerator performance and rack densities increase, the systems delivering electricity to processors must respond quickly to workload changes while maintaining efficiency and stability. Software-defined power becomes essential here, combining power semiconductors with digital control and software algorithms to dynamically manage power conversion and regulation.
Infineon said such architectures can improve efficiency, reduce power losses and support the increasing power-density requirements of next-generation AI processors. Industry analysis has identified power delivery as an important bottleneck in scaling AI data centres, particularly as electricity consumption and processor power requirements rise.
C2i was founded in Bengaluru to develop power-delivery technologies for high-performance computing and AI infrastructure. Its technology portfolio includes software-defined multiphase controllers, smart power stages, digital control technologies and system-level power architectures, including Substrate Integrated Voltage Regulators (SIVR). These technologies bring power regulation closer to the processor while enabling more intelligent control over the delivery system.
Infineon's acquisition gives it an opportunity to combine C2i's digital power-management capabilities with a broader semiconductor portfolio spanning conventional silicon, silicon carbide and gallium nitride technologies. The combined approach aims to develop power systems that respond more precisely to changing AI workloads, with future SIVR solutions as an area where the companies can collaborate.
The acquisition expands Infineon's innovation footprint in India and strengthens its global R&D capabilities. Infineon currently employs approximately 2,800 people across multiple locations in India. For India's semiconductor ecosystem, the deal illustrates a path beyond conventional chip manufacturing, with global semiconductor companies expanding specialised design, architecture and engineering capabilities. C2i, founded by experienced power-semiconductor engineers, had raised $15 million in Series A funding led by Peak XV Partners in February, according to TechCrunch.
The Infineon-C2i combination highlights how AI infrastructure is expanding the role of power electronics. Much of the attention around AI data centres has focused on GPUs, networking, memory, cooling and construction, yet power delivery is becoming another strategic layer as high-performance processors require large amounts of electricity and create rapid demand fluctuations. For semiconductor companies, this creates an opportunity to move beyond individual components and provide integrated power-management architectures.
As AI compute becomes more power-intensive, controlling and optimising how electricity reaches the processor is becoming an increasingly important part of the data-centre technology stack. With the C2i acquisition now complete, Infineon is positioning its Bengaluru engineering organisation to play a larger role in that next phase of AI infrastructure development.
