First dc/dc converter to provide 800-W in one module

The QBVE067A0B Barracuda-series dc/dc converters provide up to 800 W of 12-Vdc output power from a maximum load current of 67 A and an input voltage range from 40 to 60 V. The new converters provide the highest power density available in the industry today for 12-V solutions. Previously, two parallel 400-W converters would be needed to facilitate 800 W of power. The converters feature an industry-standard, DOSA-compliant quarter-brick footprint, measuring just 58.4 by 36.8 by 10.7-mm.

The dc/dc converters incorporate digital control, synchronous rectification technology, a fully regulated control topology and innovative packaging techniques to achieve efficiencies in excess of 96% at 12-V output voltages. The output is fully isolated at 2,250 V from the input, allowing for versatile polarity configurations and grounding connections. In addition, the converters feature built-in filtering for both input and output, minimizing the need for external filtering. They suit installations such as 12-V intermediate bus applications where multiple low voltages are subsequently generated using PoL converters. Other applications include distributed power architectures, servers and storage applications, supercomputers, automatic test equipment and networking equipment such as power over Ethernet and high-speed 5G networks.
