Infineon Technologies AG announced the acquisition of C2i Semiconductors on 24 August 2026.
The transaction is expected to close within the third quarter of 2026.
Financial terms of the acquisition remain undisclosed.
Infineon aims to integrate C2i's digital power expertise with its own global semiconductor portfolio.
Both teams will jointly build vertical power distribution methods alongside on-package voltage regulation modules.
Infineon intends to build an Indian technical hub dedicated to advancing software-controlled power systems.

The acquisition supports Infineon's strategy to enhance power solutions for AI data centers and HPC platforms.
C2i's technology helps regulate electricity for GPUs and CPUs, which is critical for high-performance AI servers.
The deal aligns with India's Semicon 2.0 policy, which recently allocated Rs 1.27 lakh crore for the sector.

C2i is a fabless semiconductor company founded in 2024.
The team builds intelligent power stages and algorithm-guided multi-channel regulators for modern machine-learning facilities.
Its systems manage power delivery from the grid directly to the processor core.
The company's technology improves power-stage efficiency, saving significant energy per server board.
C2i's first smart power-stage chip expects first silicon within months of the announcement.
A second product, a controller for multiple power stages, is scheduled for tape-out in October 2026.
