OmniOn Power has introduced the Osprey family of high-power, non-isolated DC-DC bus converters to address the increasing power demands of advanced technologies such as artificial intelligence (AI), large language models (LLMs), and machine learning (ML). This newly launched product line features three models: the 2-kilowatt (kW) QODE167A0B, 1.6kW QODE136A0B, and 1.3kW QODE108A0B. Notably, the 2kW module is among the most powerful bus converters currently available in the industry-standard DOSA quarter-brick footprint.

Meeting the High-Efficiency Power Needs of AI

Data centers worldwide currently consume 1-2% of all global power, and with recent advancements in AI technology, this share is predicted to rise to 3-4% by the end of the decade. Goldman Sachs Research estimates data center power demand will grow 160% by 2030, with regions like Taiwan leading the swift market uptick.

“As AI workloads continue to grow, the unprecedented amount of power being consumed by AI server racks has created an intense demand for cost-effective power solutions that provide high efficiency and power density,” said Vito Savino, data center and wireline segment leader for OmniOn Power. “Our new Osprey family of non-isolated bus converters addresses this challenge head-on, helping customers meet the needs of the latest graphics processing units (GPUs) and enabling them to continue to push the boundaries of AI innovation.”

Boasting peak efficiencies of up to 97.6%, the new Osprey bus converters feature a 40-60 VDC input range and can transform 48 V unregulated DC rack voltages into the regulated 12 VDC output power required by high-performance GPUs with minimal power loss. The converters incorporate digital control, synchronous rectification technology, a regulated control topology, and innovative packaging techniques to achieve high efficiencies and provide low output ripple and noise.

The modules offer a wide operating temperature range of -40°C to 85°C and incorporate a heat plate that allows for external heat sinks to be attached or for contact with a cold wall. The Osprey converters integrate a PMBus interface for power management and feature a variety of built-in protections, including output overcurrent and over voltage protection, over temperature protection, and input under and over voltage lockout.
