OmniOn launches efficient Osprey bus converters for AI

OmniOn Power has introduced new QODN Osprey bus converter models for AI data centres and high-density compute platforms, expanding its Osprey family with higher-power 48/54V-to-12V conversion products.

The range includes four models: the 2,600W QODN217, the 2,000W QODN167, the 1,600W QODN136 and the 1,300W QODN108. The products retain the quarter-brick footprint used by earlier Osprey modules while offering higher efficiency than the previous-generation QODE line.

The launch targets a data centre market where electricity demand is rising as accelerator servers, GPU baseboards and other dense compute systems require more board-level power. At the same time, operators are under pressure to limit conversion losses as they manage heat and cooling demands in increasingly dense server racks.

The converters are designed for AI data centres, 48V distributed power architectures and regulated 12V intermediate bus applications. They are intended to help customers address power conversion and thermal constraints as rack power densities increase.

Across the new line, the highest stated peak efficiency is 98.5%. OmniOn said the 2,600W QODN217 reaches 98.5% peak efficiency, while the 2,000W QODN167 delivers 98% full-load efficiency at 54V and peak efficiency above 98.5%.

The 1,600W QODN136 delivers 98.1% full-load efficiency at 54V and 98.5% peak efficiency, according to the company. The 1,300W QODN108 delivers 98.1% full-load efficiency at 54V and peak efficiency above 98.4%.

A key design point is compatibility with existing form factors. The new modules maintain a modified DOSA quarter-brick footprint measuring 58.4 mm by 36.8 mm by 14.5 mm, allowing migration from first-generation QODE modules without increasing board-space requirements.

Efficiency focus

OmniOn is positioning the products around the economics of efficiency in large AI installations, where small improvements in power conversion can have broader cost effects when multiplied across many systems.

"When looking at the power demands of AI data centers, even incremental efficiency gains can deliver significant cost benefits at scale," said Philip Zuk, Senior Vice President and General Manager of OmniOn Power's AI and Data Centre business. "Our latest Osprey-series bus converters provide peak efficiencies up to 98.5% in the same quarter-brick footprint as our previous-generation Osprey bus converters, delivering up to a 1% efficiency improvement without increasing board-space requirements."

Beyond efficiency figures, the company has included management and protection features aimed at data centre operators and equipment designers. These include a PMBus interface, remote on/off, remote sense, power-good signalling, firmware updates over I2C and black-box fault logging.

The modules also include output overcurrent, output overvoltage, overtemperature, and input under- and overvoltage protection. They support 40-60V input and regulated 12V output for hyperscale, enterprise and Open Compute Project-inspired distributed power systems.

Operating temperature is listed at -40°C to +85°C. That reflects the need for components that can function under varying thermal conditions in networking, compute and industrial environments, although the main commercial emphasis of this launch is AI infrastructure.

The products arrive as suppliers across the power electronics market respond to rapid spending on AI servers and related equipment. Growth in processor power draw has increased scrutiny on supporting layers inside systems, including conversion stages between facility power and the voltages used on boards and subsystems.

For operators building large clusters, conversion efficiency affects both direct energy use and the amount of waste heat cooling systems must remove. In dense racks running continuously, those factors can influence infrastructure design choices as much as the performance of the compute hardware itself.

OmniOn, based in Plano, Texas, with manufacturing facilities in North America and Asia, supplies power conversion products for data centre, telecommunications and industrial markets. With the Osprey update, it is seeking to strengthen its position in a segment where thermal headroom, footprint constraints and energy losses are becoming more closely linked to AI deployment costs.
