Vertical power platform cuts AI thermal bottlenecks

Lotus Microsystems’ vStrata vertical power delivery platform targets the electrical, thermal, and mechanical challenges of AI infrastructure. The first module in the vStrata Power Series, the LS0580, is a fully integrated power-system-in-package (PSiP) that places power conversion closer to the load to reduce distribution losses and board complexity. The device has completed tape-out for leading CPU, GPU, and AI accelerator platforms, with engineering samples shipping in Q3 2026.

Built on a silicon-based substrate, vStrata combines power delivery, thermal management, and packaging in a single architecture. Designed for kiloampere-class AI workloads, the platform delivers up to 96% point-of-load efficiency while reducing power losses and thermal constraints. Its low-profile vertical architecture is enabled by silicon PIT technology, supporting ultra-thin designs below 1 mm by placing power directly beneath the processor to shorten electrical paths and improve transient response.

The vStrata platform is compatible with existing power management controllers and reference designs. Lotus is currently evaluating the platform with hyperscale customers and additional partners through an early access program.
