C2i claims its software-defined power delivery platform can achieve over 96% efficiency, lower processor temperatures by 4°C, and help a 100MW AI data center save nearly $12 million annually in energy costs.
TDK Ventures has invested in Bengaluru-based C2i Semiconductors as part of the startup’s $16.7 million Series A funding round, which also saw participation from Peak XV Partners and several semiconductor industry leaders. The investment aims to support the development of advanced power delivery technologies for next-generation AI and high-performance computing (HPC) infrastructure.
As AI workloads continue to expand, data centers are facing growing energy and thermal management challenges. Modern AI accelerators are becoming increasingly power-hungry, with future chips expected to consume several times more power than current-generation processors. These rising demands are exposing inefficiencies in traditional power delivery architectures, particularly in the final stages of supplying power to processors.
Founded in 2024 by a team of former Texas Instruments engineers, C2i is addressing this challenge through a software-defined voltage regulator platform designed to improve power conversion efficiency and reduce energy losses. The company’s technology combines intelligent power stages, programmable controllers, and a modular architecture that can scale to support the requirements of future AI systems.
According to C2i, its platform can achieve power conversion efficiency exceeding 96%, compared with approximately 94% for conventional solutions. The startup estimates that these improvements could generate substantial cost savings for large AI facilities while also reducing heat generation.
In a 100MW AI data center, the technology is projected to save roughly $12 million in annual energy costs. Additionally, processors powered by the platform could operate up to 4°C cooler, helping improve hardware reliability and extend the lifespan of expensive AI infrastructure.
TDK Ventures said the investment reflects its focus on supporting breakthrough technologies that enable the next generation of digital and energy transformation. The company believes efficient power delivery will become increasingly critical as AI computing scales worldwide.
C2i plans to use the funding and TDK’s ecosystem support to accelerate product development and move toward large-scale deployment in AI and HPC environments.
