US chipmaker Onsemi has acquired Aura Semiconductor’s Vcore power technologies for an undisclosed amount.

The deal is expected to close in the fourth quarter of 2025.

In a statement, Arizona-based Onsemi said the deal would enhance its power management portfolio and roadmap, “accelerating the company’s vision to address the complete power tree in AI data center applications, from grid to core.”

Founded in India in 2011, Aura Semiconductor describes itself as a “multinational fabless semiconductor company that designs and supplies the industry with leading Mixed Signal Integrated Circuits solutions.” Products offered by the company include a number of controllers and power solutions targeting the data center industry.

By integrating Aura’s technology with Onsemi’s currently available state transformers, power supply units, and 800 VDC distribution products, the chipmaker said it will become “one of the few companies capable of meeting the stringent power requirements of modern AI infrastructure with scalable, practical designs.”

"This acquisition underscores our commitment to solving the energy and efficiency demands of tomorrow’s AI data centers by offering a full range of differentiated intelligent power solutions,” said Sudhir Gopalswamy, group president of the Intelligent Sensing and Analog and Mixed-Signal Group, Onsemi. “Integrating these technologies into our broader power management portfolio will enable us to deliver solutions with superior power density, efficiency, and thermals and enable more compute capacity per rack."

This is the second acquisition undertaken by Onsemi this year. In January, the company purchased the Silicon Carbide Junction Field-Effect Transistor (SiC JFET) technology business, including the United Silicon Carbide subsidiary, from Qorvo for $115 million in cash.

At the time, the chipmaker said the acquisition would complement its extensive EliteSiC power portfolio, allowing the company to address the need for high energy efficiency and power density in the AC-DC stage in power supply units for AI data centers.

Three months later, Onsemi scrapped its efforts to acquire Allegro MicroSystems for $6.9 billion, after Allegro described the proposed purchase as “unsolicited” and said the company’s board of directors had determined the proposal “was inadequate.”
