OmniOn Power has developed a new family of high-power, non-isolated dc-dc bus converters for applications including AI, large language models, and machine learning. The Osprey family includes three modules: the 2-kilowatt QODE167A0B, 1.6kW QODE136A0B, and 1.3kW QODE108A0B. The converters utilize the DOSA standard quarter-brick footprint.
The Osprey bus converters operate with a 40-60 V DC input range and convert 48V unregulated DC rack voltages to regulated 12 V DC output. The modules achieve 97.6% peak efficiency through digital control, synchronous rectification technology, regulated control topology, and advanced packaging techniques. These design elements also contribute to low output ripple and noise characteristics.
Technical specifications include an operational temperature range from -40°C to 85°C and an integrated heat plate compatible with external heat sinks or cold wall contact cooling methods. The converters incorporate a PMBus interface for power management functionality.
Protection features built into the Osprey family include output overcurrent protection, output overvoltage protection, overtemperature protection, and input under/overvoltage lockout. These safeguards help ensure reliable operation in demanding computing environments where continuous uptime is critical.
