OmniOn Power Launches DC/DC Bus Converters for AI Servers

The evolution of artificial intelligence and machine learning places pressure on data centers to deliver more power while maintaining efficiency. They demand an unprecedented energy level to sustain operations as AI-driven workloads increase in complexity. Data centers are already responsible for consuming an estimated 1-2% of global electricity and are expected to see their power consumption rise to as much as 4% by 2030. Addressing this challenge requires innovations that enhance power efficiency while meeting the growing energy needs of AI applications.

OmniOn Power has introduced its latest solution to this problem: the Osprey-series nonisolated DC/DC bus converters. Engineered to support power-hungry AI applications, these converters deliver high power density with peak efficiencies exceeding 97%. The Osprey family consists of three models—the 2-kilowatt (kW) QODE167A0B, 1.6 kW QODE136A0B, and 1.3 kW QODE108A0B—offering a range of power outputs for AI server racks. These converters optimize power usage while minimizing losses by converting 48 V unregulated DC input into the stable 12 VDC output required by modern graphics processing units (GPU).

High Performance in a Compact Design

One standout feature of the Osprey series converters is their ability to deliver high power within a compact footprint. Conforming to industry-standard modified DOSA quarter-brick sizes, these converters provide more power in less space, making them ideal for the dense, high-performance server environments required by AI and ML applications.

Their design includes a 40-60 VDC input range and synchronous rectification technology, which enables them to achieve high peak efficiencies. By incorporating digital control and regulated control topology, the converters ensure stable and reliable power delivery, even under heavy AI processing loads. Their low output ripple and noise also make them suitable for sensitive GPU operations where consistent power is important for maintaining performance and system stability.

Durability and Advanced Power Management Features

The Osprey-series converters are built for durability and can withstand the demanding conditions of high-performance data centers. Their operating temperature ranges from -40°C to 85°C, and they feature a heat plate for external heat sinks or cold wall contact, enabling efficient thermal management. These features are essential for maintaining peak efficiency in environments where excessive heat can compromise performance.

Additionally, the Osprey converters integrate a PMBus interface. This enables precise power management and real-time monitoring. Built-in protections such as output overcurrent, overvoltage, and over-temperature safeguards ensure the converters operate reliably under various load conditions. Input under-voltage and overvoltage lockout features further contribute to the system’s resilience, protecting data center infrastructure from power fluctuations.

Enabling the Future of AI Innovation

The need for efficient power solutions will only grow as AI continues to push technological boundaries. OmniOn Power’s Osprey-series nonisolated bus converters offer a forward-looking solution, ensuring that AI data centers can sustain increasing workloads without sacrificing energy efficiency. With their high power density, compact design, and thermal management, these converters represent an advancement in data center power technology. By tackling AI's mounting power demands head-on, OmniOn Power is paving the way for more efficient and scalable data center infrastructure.
