onsemi’s Strategic Move: Acquiring Vcore Power Technologies from Aura

Date: September 24, 2025

What Happened

onsemi officially announced that it will acquire Vcore power technologies and associated IP licenses from Aura Semiconductor. The goal is to accelerate onsemi’s power management roadmap across the full power tree from grid to core, especially for AI data centers. (onsemi press release) onsemi.com

Why It Matters

This deal strengthens onsemi’s ability to deliver more efficient, high density, thermally robust power solutions. These are key performance factors in AI racks where power draw and heat management are growing bottlenecks. By plugging Aura’s technology into its existing silicon and SiC platforms, onsemi aims to offer more integrated offerings across solid state transformers, DC distribution, and core power delivery. onsemi.com

Financial and Timing Details

  • The acquisition is expected to close in Q4 2025, pending customary closing conditions.
  • onsemi projects minimal impact to its GAAP and non GAAP earnings per share in the first fiscal year after the transaction, with the deal becoming accretive afterward.

Competitive and Strategic Implications

  • For AI infrastructure builders, better power systems translate to more compute per rack and improved energy efficiency, which hyperscalers and cloud providers need.
  • The move raises the bar for other power management firms that may not offer full grid to core architectures in a single stack.
  • It signals that onsemi sees power delivery as a strategic lever, not just a complementary business to its traditional analog and mixed signal lines.
  • This is also onsemi’s second acquisition this year, following its earlier purchase of Qorvo’s SiC JFET technology, which is already influencing its power portfolio.

What to Watch Next

  • How well Aura’s Vcore technologies integrate with onsemi’s existing power technologies
  • Which hyperscaler or AI firms begin to deploy power systems using the new integrated solutions
  • Whether onsemi delivers on its earnings guidance and margin improvement
  • Whether this deal signals more consolidation in AI power systems
