Reportedly an industry first, the BMR453 series quarter-brick dc/dc converters integrate a digital-control platform within the modules themselves. This approach promises to free up real estate for improving power density. With a 96% efficiency, the components deliver up to 400W of output power or up to 33A with a ±2% accuracy. Input voltage range is 36V to 75V and output voltages are variable from 8.5V to 13.5V. Target applications include systems that must use a telecom input voltage with battery backup or both -48V and -60V nominal input voltages. The converters meet insulation requirements of EN60950 and come with industry-standard features such as remote sense, configurable protections (over-temperature, over-current and over-voltage), switching frequency synchronization, PMBus interface, power good, and programmable power management. An evaluation kit is available that includes an evaluation board, operating manual, CD containing a graphic user interface, and cables. Price for the BMR453 with a communication interface will be $55.50 each in OEM quantities. ERICSSON INC., Plano, TX. (972) 583-0000.
