Every chip needs its supply voltage converted, and the converters take up board space and waste energy as heat. Lotus Microsystems, a Danish company founded on research at the Technical University of Denmark (DTU), Harvard, Fraunhofer and IMEC, builds what it calls "high-performance integrated power modules" that combine advanced packaging, new converter designs and its own silicon power interposer, making them small enough to sit very close to the chip they feed.
The European Innovation Council granted €2,261,783 towards a €3.23 million project, and the EIC took part in a DKK 60 million round in December 2023 alongside Noon Ventures. The project ended in September 2025 with pre-production modules. In June 2026 Lotus launched vStrata, a power module for AI data centres, with engineering samples going to hyperscale customers.

Where Lotus Microsystems Stands Today
On 8 June 2026 Lotus launched the vStrata LSC0580, which it calls its first vertical power delivery module for AI infrastructure, claiming up to 96% point-of-load efficiency and more than 50% lower conversion losses. Engineering samples were due to ship in the third quarter of 2026 to tier-1 hyperscalers in an early access programme, which it did not name. Its news page also lists distribution partnerships and a new sales director, and the website now has a thermal management product section.
The Technology: A Power Supply in the Silicon
Power converters normally use discrete inductors and capacitors on the circuit board. Lotus integrates them in silicon interposers, a "Power Interposer" and an "Active Power Interposer" that also contains switching circuits, so the converter becomes a component that can be stacked under or beside a processor. According to the CORDIS report, the project produced "the smallest fully integrated boost converter power supply available today".
"We have reached a point where AI compute performance is constrained by physical architecture."
Hans Hasselby-Andersen, CEO, Lotus Microsystems, June 2026What the EIC Project Promised, and What CORDIS Shows
The project ran from November 2022 to September 2025. CORDIS reports that the main technologies advanced "from TRL 3-4 to TRL 7-8", that engineering samples of both interposer technologies were produced and validated, that pilot and pre-production packaging runs of the LMU20P1 module showed stable performance, and that an evaluation board was built for customers. It adds that further research, demonstrations with early customers and access to industrial manufacturing capacity are still needed.

What Has Happened Since the Award
The Money
In December 2023 Lotus announced DKK 60 million from Noon Ventures and the European Innovation Council, to fund development projects with international customers, R&D and market entry, and the appointment of Hans Hasselby-Andersen, who had founded Merus Audio and sold it to Infineon, as chief executive. The EIC's share was not disclosed. On 31 July 2025 Nordic9 reported a further equity round of $8.4 million from Noon Ventures and EIFO, Denmark's Export and Investment Fund, bringing total funding to $17.1 million.
What cannot be checked
Who the hyperscale customers are, whether any have placed volume orders, and Lotus's revenue are not public.
Why Europe Should Care
Lotus's own pitch is that AI compute is now limited by how power reaches the chip and how heat is removed. If that holds, component suppliers to hyperscale data centres gain a large market, and Lotus is a Danish example with the EU as an early investor.
What the project promised
The world's smallest power converters, taken to industrial readiness.
What the record shows
Pre-production modules, a DKK 60M round with the EIC and an AI power module in sampling.
The Verdict
On track, not yet in volume
The EIC project did what deep-tech hardware projects should: it took the technology from lab to pre-production, and the company raised private and EIC money on the back of it. Lotus has since repositioned towards AI data centres. The test is whether sampling with hyperscalers becomes orders and volume manufacturing.
