Based on a digital core controller embedding an Ericsson efficiency optimizer algorithm, and fully compliant with the “Five-pin” de-facto industry standard for intermediate bus converters (IBC), Ericsson Power Modules introduces a series of variants to its BMR453 and BMR454 DC/DC converters. 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 5V to 13V. 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 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.
