Lotus Microsystems has launched vStrata, a new power-delivery architecture designed to boost data-center power efficiency. The company says the platform is especially relevant for AI-driven workloads, which are pushing up power demand and cooling costs across hyperscale facilities.

What vStrata Does

At the core of vStrata is Lotus’s proprietary Power Interposer Technology (PIT), a silicon-based interposer that brings power conversion and delivery closer to the processor package. The PIT uses a vertical power delivery (VPD) chip and package to send electrical power directly through the package stack to the processor, rather than through longer, less efficient paths.

By shortening current paths and integrating thermal management into the power-delivery structure, vStrata aims to reduce conversion losses while improving cooling efficiency. According to Lotus, the module can reach point-of-load efficiencies of up to 96% and cut power-conversion losses by more than 50% compared with conventional approaches.

Power Savings and Cooling Impact

No power converter is 100% efficient, and around 90% is typical. Lotus’s PIT reaches 96%, which translates to roughly a 60% reduction in power loss. With banks of power-consuming GPUs, those savings accumulate quickly, potentially allowing data centers to use air cooling instead of being forced to switch to expensive liquid cooling.

Lotus CEO Hans Hasselby-Andersen said the technology reduces the energy needed for cooling data centers and also helps lower water consumption.

Compatibility and Adoption

vStrata is compatible with existing power-management controllers and reference designs, which could make adoption easier for semiconductor and system vendors. The platform is delivered as power supplies, and Lotus is working with major server vendors and hyperscalers.

However, the new power supplies are not suitable for retrofitting into existing server racks. As Hasselby-Andersen noted, there is no industry standard for server power supply footprints, so there is no default size that existing racks can reliably support
