A high-efficiency DC/DC converter with a compact design for peak performance in applications like powering Point of Load (PoL) converters.
Flex Power Modules has launched the BMR314, a non-isolated DC/DC converter with a consistent 4:1 down-conversion ratio suitable for intermediate bus applications. The company claims the compact yet powerful component delivers a continuous 800 W and peaks at 1.5 kW, all from an ultra-compact package measuring only 23.4 x 17.8 x 9.6 mm. It accepts an input of 38-60 VDC (with a peak of 68 VDC) and provides an output ranging from 9.5 to 15 VDC. In collaboration with the semiconductor manufacturing company Onsemi, the DC/DC converter has been designed to target applications like powering Point of Load (PoL) converters in AI and datacom centres.
The converter addresses challenges like high peak loads, limited space, and the need for energy conservation with its peak efficiency of 97.4% in a streamlined package designed for cold wall cooling. It can deliver up to 70 A of output current and is fortified against over-temperature, input under-voltage, and output over-current, over-voltage, and short circuits. Additionally, it offers comprehensive control and monitoring via a PMBus interface. The product also integrates with the Flex Power Designer software, facilitating configuration, performance simulation, and monitoring.
The press release says that the DC/DC converter is designed to operate within a temperature range of -20 °C to +125°C at a designated hot spot. Designed for integration, the BMR314 is a surface mount device featuring Land Grid Array (LGA) terminations, adhering to industry-standard dimensions and pin configurations. It complies with the safety standards set by IEC/EN/UL 62368-1 for non-isolated converters.
David Xie, Director R&D and Product Management Shanghai of Flex Power Modules comments, “Our new BMR314 IBC DC/DC can help to reduce size, weight and costs in critical data centre applications, while providing the flexibility to handle high peak safety loads.”
