Power Integrations unveils ultra-slim auxiliary power reference designs aimed at NVIDIA data center systems

Power Integrations (NASDAQ:POWI) has released a pair of ultra-slim auxiliary power supply reference designs targeted at data center architectures that include NVIDIA’s (NASDAQ:NVDA) processors and platforms, according to a report published Monday. The company said the designs are intended to support NVIDIA-based servers where system builders need reliable off-main power for components that must stay powered during a wider range of operating states.

Auxiliary power supplies provide power to parts of a system that do not run directly off the main high-power rails used by the primary compute components. In data centers, that often means circuitry involved in management, monitoring, and maintaining operational readiness, while minimizing wasted power and allowing tighter physical integration in server chassis.

In its announcement covered by Yahoo Finance, Power Integrations said it introduced ultra-slim reference designs in two wattage categories: 15 W and 35 W. Reference designs are pre-engineered power supply blueprints that help customers accelerate development by starting from a tested architecture rather than designing the power stage from scratch.

The post characterizes the new boards as optimized for slim form factors, suggesting the company is responding to customer demand for higher density and more constrained space inside next-generation server systems. Power Integrations did not, in the available report text, provide additional technical performance metrics such as efficiency targets, operating temperature ranges, switching frequency choices, or specific component selections.

The timing also fits into a broader pattern in the data center supply chain, where power management partners work closely with compute ecosystem players to ensure power architectures can scale with workload growth. As GPUs and accelerators increase overall power demand, system integrators still need efficient, dependable auxiliary rails that fit within mechanical constraints and support data center reliability goals.

The report did not disclose licensing details, certification timelines, or whether the designs are already being adopted by specific server OEMs or system integrators. It also did not specify whether the reference designs are tied to a particular NVIDIA platform generation, rack-level power scheme, or thermal envelope, beyond the general “NVIDIA data center architecture” framing.

For investors and customers tracking the power ecosystem, the key question will be how quickly reference designs translate into measurable revenue through design wins and shipments. That linkage is typically not immediate and can depend on how long qualification cycles take at server OEMs, as well as the extent to which system designs require the auxiliary power module form factor that Power Integrations is now promoting.
