OmniOn Power has announced new high-efficiency, high-power additions to its Osprey bus converter family, designed for AI data centers, high-density computing, 48V distributed power architectures, and regulated 12V intermediate bus applications. The new QODN bus converters deliver higher efficiency than the previous-generation QODE modules while keeping the same industry-standard quarter-brick physical footprint.
The new lineup includes four models. The 2,600W QODN217 offers 97.9% full-load efficiency at 54V, with peak efficiency exceeding 98.4%. The 2,000W QODN167 offers 98% full-load efficiency at 54V, with peak efficiency exceeding 98.5%. The 1,600W QODN136 offers 98.1% full-load efficiency at 54V, with peak efficiency exceeding 98.5%. And the 1,300W QODN108 offers 98.1% full-load efficiency at 54V, with peak efficiency exceeding 98.4%.
As accelerator servers, GPU baseboards, and other high-density compute platforms drive sharp increases in board-level power demand, engineers increasingly need power solutions that offer both higher power capacity and higher efficiency. There's also growing emphasis on reducing conversion losses, meaning energy wasted as heat during voltage conversion, to help preserve thermal headroom and ease cooling requirements in dense, always-on AI and networking infrastructure.
Philip Zuk, senior vice president and general manager of OmniOn Power's AI and Data Center business, said that given the power demands of AI data centers, even small efficiency gains can translate into significant cost savings at scale. He said the latest Osprey-series bus converters deliver peak efficiency up to 98.5% in the same quarter-brick footprint as the previous generation, offering up to a 1% efficiency improvement without requiring any additional board space.
The latest Osprey-series converters deliver high-current, high-efficiency 48/54V-to-12V voltage conversion, helping address potential power conversion and thermal bottlenecks as AI server racks continue scaling toward higher power densities. The converters also maintain high, flat efficiency curves across their full operating range, meeting the demands of today's AI workloads, which often run at varying load levels rather than a single fixed point.
Additional key features of the QODN bus converters include support for 40-60V input with regulated 12V output, suited to hyperscale, enterprise, and Open Compute Project (OCP)-inspired distributed power systems; an integrated PMBus interface offering remote on/off control, remote voltage sensing, power-good status signaling, firmware updates over I2C, and black-box fault logging for diagnosing issues after the fact; built-in protection against output overcurrent, output overvoltage, overtemperature, and input under- and overvoltage conditions; an operating temperature range of -40°C to +85°C; and a consistent modified DOSA quarter-brick footprint (58.4mm x 36.8mm x 14.5mm) across the entire product family, making it easy for customers to migrate from first-generation QODE modules to the new QODN converters.
