TDK Corporation (TSE:6762) announced today that TDK Ventures Inc. has invested in C2i Semiconductors, a pioneer in software-defined Voltage Regulator (VR) platforms. The investment is part of C2i’s $16.7 million Series A funding round, which includes participation from Peak XV Partners and other prominent semiconductor industry leaders.
Solving the “Last-Inch” power challenge
As AI workloads drive global data center electricity demand toward an estimated 1,000 TWh by 2030, current power delivery architectures are hitting physical limits. Modern GPUs and accelerators are projected to require peak currents of up to 6,000A by 2030, creating critical “last-inch” power losses that significantly degrade efficiency. While the NVIDIA H100 (2022) required 700W, upcoming chips like the “Feynman” (2028) are projected to demand a staggering 4,500W.
C2i Semiconductors, founded in 2024 by a veteran team of former Texas Instruments technologists, addresses these bottlenecks through a fundamental rethink of “grid-to-core” power delivery.
“The transition to AI-scale compute is one of the most significant infrastructure build-outs of our generation, and it requires innovation at the very layer that delivers power to the silicon,” said Nicolas Sauvage, President of TDK Ventures. By making the power conversion more efficient, C2i is solving one of the most critical thermal and efficiency constraints of the AI era.”
Innovation through software-defined voltage regulators
C2i’s disruption lies in its proprietary IPs powering their products. The platform includes:
− Manas Controller: A software-defined Controller with a unique control architecture that is agnostic to PDN changes and processor requirements.
− Sarayu Power Stage: A smart power stage that offer better conversion efficiency with 6x the reliability
− Modular Scalability: the controller with unique features to offer as many phases of operation as required for higher current applications, also lending itself to VPD architecture and the VRs
Massive efficiency and economic impact
C2i’s platform is projected to deliver over 96% power conversion efficiency, a significant leap over the 94% found in incumbent solutions. In a 100MW AI data center, these gains—combined with reduced heat—could translate to approximately $12 million in annual energy savings. Furthermore, technology enables processors to run up to 4°C cooler, extending the usable life of expensive AI hardware.
“Our vision is to make energy flow more reliable, denser, and more efficient from the grid all the way to the processor core,” said Ram Anant, Co-founder and CEO of C2i Semiconductors. “Partnering with TDK Ventures provides us with deep insights into advanced passives and access to a global ecosystem that will accelerate our path to mass production.”
