Compact DC/DC Converter For AI And Datacom Centres

A high-efficiency DC/DC converter with a compact design for peak efficiency in purposes like powering Level of Load (PoL) converters.

DC/DC converter

Flex Energy Modules has launched the BMR314, a non-isolated DC/DC converter with a constant 4:1 down-conversion ratio appropriate for intermediate bus purposes. The corporate claims the compact but highly effective element delivers a steady 800 W and peaks at 1.5 kW, all from an ultra-compact bundle measuring solely 23.4 x 17.8 x 9.6 mm. It accepts an enter of 38-60 VDC (with a peak of 68 VDC) and offers an output starting from 9.5 to fifteen VDC. In collaboration with the semiconductor manufacturing firm Onsemi, the DC/DC converter has been designed to focus on purposes like powering Level of Load (PoL) converters in AI and datacom centres. 

The converter addresses challenges like excessive peak masses, restricted house, and the necessity for power conservation with its peak effectivity of 97.4% in a streamlined bundle designed for chilly wall cooling. It will possibly ship as much as 70 A of output present and is fortified towards over-temperature, enter under-voltage, and output over-current, over-voltage, and brief circuits. Moreover, it affords complete management and monitoring through a PMBus interface. The product additionally integrates with the Flex Energy Designer software program, facilitating configuration, efficiency simulation, and monitoring.

The press launch says that the DC/DC converter is designed to function inside a temperature vary of -20 °C to +125°C at a chosen scorching spot. Designed for integration, the BMR314 is a floor mount machine that includes Land Grid Array (LGA) terminations, adhering to industry-standard dimensions and pin configurations. It complies with the protection requirements set by IEC/EN/UL 62368-1 for non-isolated converters. 

David Xie, Director R&D and Product Administration Shanghai of Flex Energy Modules feedback, “Our new BMR314 IBC DC/DC can assist to cut back measurement, weight and prices in vital knowledge centre purposes, whereas offering the flexibleness to deal with excessive peak security masses.”
