Flex Power Modules introduces BMR316

The compact BMR316 is ideal for other high-power IBC applications where board space is limited.

The BMR316 features a fixed 4:1 conversion ratio, efficiently stepping down 48V to 12V. It provides a continuous power output of 1kW and can deliver peak power up to 3kW. With a power density exceeding 900 W/cm³ (15 kW/in³) during peak load, the BMR316 is housed in an ultra-compact package measuring just 23.4 x 17.8 x 7.65 mm. It operates within an input range of 38 – 60V (68V peak), delivering an output of 9.5 – 15V.

The BMR316 is designed to work seamlessly with a variety of voltage regulator modules (VRMs) and Point-of-Load (PoL) converters, further converting the intermediate bus to core voltages needed further downstream in AI and datacom centres. These environments require high peak power handling, efficient use of board space, and optimised energy efficiency. 

With a peak efficiency of 97.7% at half load, the BMR316 enhances cooling performance by reducing thermal demands, and low-profile design make it ideal for cold wall mounting or direct-to-chip liquid cooling solutions.

Additional features include fast load-transient response, high current-monitoring accuracy, and a calculated MTBF of 7.43 million hours. The BMR316 meets the latest IEC/EN/UL 62368-1 safety standards with built-in protection and warning systems.

The product is also supported by Flex Power Designer, a software tool that offers configuration, performance simulation, and monitoring capabilities, all with full control via a PMBus interface.
