Ericsson has introduced a DC-DC converter, available in an industry-standard quarter-brick footprint. The BMR453-0108/014, provides an output voltage of 12.45V with an output current of 60A, delivering a total output power of 711W. The BMR453-0108/014 combines two Ericsson BMR453 series power modules, assembled in parallel and offers a power density as high as 33.38W/cm2 (215W/in2) while it embeds digital core controllers.
Due to its built-in energy optimization capabilities, the BMR453-0108/014 delivers 96.9% efficiency at half load and up to 95.8% at full load. Specially designed for data communications applications requiring high power and a regulated intermediate bus converter within a limited footprint, a key benefit of the BMR453-0108/014 is that it offers a 44 to 75V input voltage range and is compatible with 48, 52 and 60V systems.
Based on the BMR453 platform, the module is useful for powering networking applications such as network processing encryption, load balancing and managing data-center traffic, in addition to powering arrays of disk drives, which require a stable voltage to guarantee data integrity. Measuring 57.9 x 36.8 x 24.5 mm (2.28 x 1.45 x 0.965 in), the device's footprint is fully compatible with 'five-pin' quarter-brick intermediate bus converters, also simplifying migration from static intermediate bus architectures to more advanced topologies such as Dynamic Bus Voltage.
Offering an MTBF (Mean-Time-Before-Failure) of 1.2 million hours, the BMR453-0108/014 meets safety requirements according to IEC/EN/UL 60950-1, and offers input/output isolation of 1500V(dc) and protection features including over-temperature, over current, and over- and under-voltage. The BMR453-0108/014 is available either with a baseplate for easy assembling to cold-wall cooling or with a built-on heatsink for use in forced-air-cooling applications.
