BENGALURU | 24 August 2026: German semiconductor major Infineon Technologies has announced the acquisition of Bengaluru-based C2i Semiconductors, strengthening its capabilities in power-management technologies for AI data centres and expanding its global R&D footprint in India.

C2i specialises in software-defined multiphase controllers, smart power stages and system-level power architectures designed for AI data-centre applications. The acquisition will add this specialised expertise to Infineon’s portfolio of power semiconductor technologies and create a new Centre of Excellence for digital power technologies in India. The transaction is expected to close in the third quarter of 2026.

The development is significant beyond the transaction itself. It places Bengaluru-developed deep-tech capability and IP directly into Infineon’s global innovation network, reflecting the expanding role of India in the design of technologies underpinning next-generation AI infrastructure.

KEY HIGHLIGHTS

  • A New Digital Power CoE: Infineon will establish a Centre of Excellence for digital power technologies in India, strengthening the country’s role within its global R&D network.
  • AI Infrastructure at the Core: C2i’s expertise covers software-defined power management, multiphase controllers and system-level power architectures for increasingly demanding AI data-centre environments.
  • Vertical Power Delivery: The combined capabilities will support next-generation vertical power delivery architectures, including Substrate Integrated Voltage Regulators (SIVR), designed to address the growing power-density requirements of AI processors.
  • India’s Deep-Tech Scale: The transaction adds specialised expertise to Infineon’s existing Indian engineering base of approximately 2,800 employees.
  • From Startup Innovation to Global Scale: C2i’s specialised technology will be combined with Infineon’s global semiconductor portfolio, application expertise and manufacturing capabilities across silicon, silicon carbide (SiC) and gallium nitride (GaN).

Headquartered in Neubiberg, Germany, Infineon Technologies AG is a publicly traded multinational semiconductor manufacturer that generated €14.66 billion in FY25 revenue with a global workforce of approximately 57,000 across its automotive, power systems, and edge systems divisions. The enterprise maintains a robust R&D footprint in Bengaluru with over 2,800 employees; a capability base it is now expanding through the integration of C2i Semiconductors.

Established in Bengaluru, C2i is a fabless semiconductor startup specializing in software-defined power management integrated circuits (PMICs) and vertical power delivery architectures designed to stabilize energy consumption for high-performance GPUs in AI data centers. Prior to the acquisition, the startup had secured $35.7 million in institutional funding from deep-tech investors including Peak XV Partners, TDK Ventures, and semiconductor industry veteran Lip-Bu Tan

WHY POWER MANAGEMENT IS BECOMING AN AI INFRASTRUCTURE IMPERATIVE

The rapid deployment of AI accelerators is creating a new engineering challenge for data-centre operators: how to deliver increasing amounts of power efficiently, reliably and responsively to increasingly power-dense computing systems.

AI processors generate highly dynamic power requirements as workloads change. This places greater demands on power-delivery systems to respond rapidly while maintaining efficiency and system stability. C2i’s software-defined approach combines advanced power semiconductors, digital control and software algorithms to optimise power conversion, regulation and system performance in real time. Its system-level architecture spans the power-delivery path from the grid to the processor core. For Infineon, the acquisition therefore extends its AI data-centre proposition beyond individual semiconductor components towards integrated power-delivery architectures.

Industry Insights

Proofpoint’s expansion highlights several broader shifts in India’s capability-centre ecosystem:

  1. India Is Becoming an IP Destination, Not Just a Talent Destination: The most important signal from the acquisition is that India is increasingly participating in the creation of proprietary deep-tech IP. The value proposition is shifting from access to engineering talent towards access to technologies, architectures and specialised intellectual property developed in India.
  2. AI Infrastructure Is Creating New GCC and R&D Mandates: AI’s infrastructure requirements are expanding the capability agenda beyond compute and software. Power electronics, thermal management, semiconductor architecture and energy efficiency are becoming strategic technology domains. This creates new opportunities for India-based R&D centres and Centres of Excellence.
  3. Acquisitions Can Accelerate Capability Building: The Infineon-C2i transaction demonstrates how an established multinational can use M&A to acquire specialised capability, talent and IP simultaneously. Rather than building every capability internally, global enterprises can use India’s startup ecosystem as an extension of their R&D strategy.
  4. Bengaluru’s Semiconductor Ecosystem Is Deepening: The development adds another layer to Bengaluru’s semiconductor proposition. The ecosystem is increasingly extending beyond chip design and verification into power management, system architecture and AI infrastructure technologies.
  5. The AI Race Is Increasingly an Energy-Engineering Race: As AI compute scales, performance alone is no longer sufficient. Power efficiency, delivery architecture and energy management are becoming determinants of AI infrastructure economics. That creates a significant new engineering frontier for semiconductor companies and the ecosystems that support them.

THE BENGALURU DEEP-TECH PLAY

The more significant India story is the nature of the capability being acquired. C2i is not a conventional IT-services operation. Its value lies in specialised semiconductor engineering, power-management architecture and software-defined control technology.

This acquisition will further strengthen Infineon’s leadership in power solutions for AI data centers and create a new center of excellence for digital power technologies in India. C2i Semiconductors brings exceptional expertise in software-defined power management and system-level power architectures, backed by a proven highly experienced engineering team.

Infineon’s decision to integrate this capability into its global R&D network illustrates how Bengaluru’s technology ecosystem is increasingly producing intellectual property that can become part of the global product and innovation portfolios of multinational companies. The transaction also demonstrates a different pathway for GCC and R&D ecosystem development: global companies can build capability in India organically, but they can also acquire India-originated deep-tech capability and integrate it into global innovation networks.

STRATEGIC OUTLOOK

The Infineon-C2i transaction signals a more consequential shift in India’s role in the global semiconductor ecosystem. Bengaluru is increasingly emerging not only as a centre for semiconductor engineering talent, but as a source of specialised technologies and intellectual property that can be integrated into global product portfolios. As AI infrastructure becomes more power-intensive, capabilities spanning power management, semiconductor design, system architecture and energy efficiency are likely to become increasingly important components of India’s next generation of global R&D mandates.
