onsemi Acquires Aura Semiconductor's Vcore Technology

Recently, onsemi announced an agreement with Aura Semiconductor to acquire its Vcore power technology and related IP licenses. This move is set to strengthen onsemi's power management portfolio and support its long-term roadmap of building a complete power tree for AI data centers — from the grid to the core.

Sudhir Gopalswamy, President of onsemi's Intelligent Sensing and Analog Mixed-Signal Division, explained that the acquisition reflects the company's commitment to delivering advanced, energy-efficient power solutions for next-generation AI data centers. By integrating Aura's Vcore technology, onsemi aims to deliver higher power density, better thermal performance, and improved efficiency to boost computing power per rack.

Aura Semiconductor, founded in 2011 and headquartered in Bangalore with offices in Shenzhen, Shanghai, and Milpitas, specializes in mixed-signal IC solutions for communications, data centers, IoT, and automotive applications. Its product lineup spans timing systems, power management, RF signal chains, and sensors such as MEMS IMUs, water flow meters, and position detectors.

Vcore — the core voltage supplied to CPUs and GPUs — is critical for stable performance and longevity of processors. With the rapid rise of AI workloads, demand for reliable and scalable Vcore solutions has soared. onsemi, already strong in silicon and SiC technologies, brings expertise in solid-state transformers, high-voltage DC distribution, and advanced power delivery.

This acquisition positions onsemi as one of the few companies able to meet the demanding power needs of modern AI infrastructure with scalable and practical designs, reinforcing its leadership in global power management.
