/> With 96.5% peak efficiency and a substantially flat efficiency curve from 15% to 100% load, the quarter-brick BMR453 offers up to 396W output power (or up to 33A) and the eighth-brick BMR454 offers up to 240W (or up to 20A).
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 9V or 12V output voltages.

The first versions of these products were launched in 2008. They created a new industry platform, embedding a digital core controller to deliver unprecedented levels of flexibility and efficiency via digital control and power-management.

Since the late 1990s, the Information and Communication Technology (ICT) industry has adopted a power architecture based on a main DC/DC converter powering a range of point-of-loads converters. Depending on segment and power-range, this technology, known as the Intermediate Bus Architecture (IBC), has used a variety of DC/DC converters. The demand trend is for products that offer increasing functionality, shorter time-to-market and reduced energy consumption. Today, the technology requires the use of optimized intermediate bus voltages so that power-modules perform with high efficiency throughout their operating range, from low load to full load.
