Energy-optimized, intermediate bus DC/DC converters offer high efficiency across a wide load range

The latest versions omit the digital interfaces found in early models, simplifying system design. Ericsson programs the modules in its factory for any output voltage from 5 V to 13 V. This, together with the energy optimization algorithm, ensures that the modules operate with the highest possible efficiency over wide-ranging load conditions. The result is lowest power dissipation, lowest temperature operation, highest reliability and maximum energy saving.

With 96.5% peak efficiency and a flat efficiency curve from 15% to 100% load, the quarter-brick BMR453 offers up to 396 W output power (or up to 33 A) and the eighth-brick BMR454 offers up to 240 W (or up to 20 A).

Industry-standard "Five-pin" compatibility simplifies migration from static intermediate bus architectures to more advanced topologies such as Dynamic Bus Voltage, which the latest versions of BMR453 and BM454 accommodate through their digital interface.

All BMR453 and BMR454 converters meet the insulation requirements of EN60950 and come complete with vital protection features (over-temperature, over current and over-voltage) and standard 9 V or 12 V output voltages.
