AI racks have become a power delivery problem, and Infineon’s answer is a Bangalore startup that puts software inside voltage regulation.
The Munich chipmaker said it has acquired C2i Semiconductors, whose controllers and power stages manage multiphase conversion for AI servers. Terms of the deal were not disclosed.
C2i’s technology spans vertical power delivery and substrate-integrated voltage regulators, coupling power devices with digital control loops that adjust output on millisecond timescales as AI processors slam between idle and full load.
Infineon gains an engineering team in India, where it already employs about 2,800 people, and described the country as a strategic innovation hub. Company executives said C2i’s software-defined approach to power management and system-level design was the draw.
The purchase follows Infineon’s record quarter in August, when AI power chip demand drove growth. Rack power densities climbing toward megawatt scale have made efficient voltage conversion a competitive battleground among power chip suppliers.
