Navitas Semiconductor has completed its acquisition of Claros, a developer of integrated voltage regulators for AI data centres, extending its power-delivery portfolio to the final conversion stage immediately before the processor. The Torrance, California company announced the closing on October 6.
Claros technology integrates power transistors, digital control, inductors and capacitors into a single stack used in two product families: a packaged integrated voltage regulator and an embedded integrated voltage regulator. In plain terms, the devices take the power arriving at a server board and convert it, at the last possible moment and as close to the chip as possible, into the precise low voltage a modern AI processor needs. Navitas said the products support vertical and embedded power-delivery architectures, delivering higher efficiency, faster transient response and greater power density, with a modular design that scales to the rapidly rising demands of next-generation processors.
The acquisition fills a deliberate gap. Navitas built its reputation on gallium nitride and silicon carbide power semiconductors, including high-voltage devices for 800-volt DC architectures of the kind Nvidia has promoted for AI factories. Those chips handle power further upstream, from the grid connection through the rack. Claros covers the last inch. Combined, Navitas says, it can now address the entire chain from grid to processor, a claim it will underline in a technical webinar scheduled for October 20 under the theme of breaking the AI infrastructure power wall.
That theme is more than marketing. As AI accelerators have grown more powerful, the limiting factor in many facilities is no longer the supply of chips but the supply of electricity, and the losses incurred delivering it. Every watt converted inefficiently near the processor becomes heat that must then be removed with yet more energy. Improving efficiency at the final stage is therefore equivalent to finding new capacity: the same power feed can support more computation. It is why some of the most contested engineering in the industry now happens in voltage regulation rather than in the processors themselves.
The commercial prize is sized accordingly. Navitas expects the acquisition to add at least $3.5 billion to its serviceable addressable market by 2030, taking the total above $8 billion, including its existing gallium nitride, silicon carbide and junction field-effect transistor opportunities. Coverage of the deal put its value at up to about $233 million, with roughly $216 million due at closing in cash and stock and the remainder tied to milestones. Those figures are reported terms, and the milestone structure means the final cost depends on Claros hitting its targets.
Chief Executive Chris Allexandre said in the announcement that, with power now the bottleneck for AI, improvements in delivery and efficiency are the key enablers of more computing output. Analysts writing on the deal were more measured, noting that Navitas revenue base remains small relative to the market it is chasing, that its share count has risen, and that profitability is still ahead of it. The company holds substantial cash and minimal debt, which buys time to prove the combined portfolio in customer designs.
The proof will come in design wins. Power components are qualified slowly and replaced reluctantly, so the value of owning the full chain from grid to chip is the chance to be specified across more of the board at once. If AI data centres standardise on high-voltage DC distribution, as the largest operators intend, the last-inch regulators Claros sells become a standard part of every rack. Navitas has now bought its seat at that table.
