The BMR456 3E dc/dc converter is the first model in the second generation of digital Advanced Bus Converter products. It targets information and communication technology (ICT) applications that require fast response time, tightly regulated intermediate bus voltages and high efficiency at any point of operation, to reduce power consumption. The device is based on the FRIDA II platform and firmware to reduce energy consumption. It delivers a typical efficiency of 96.5%.
The regulated digital dc/dc converters are based on a 32-bit ARM microcontroller that embeds the FRIDA II firmware keeping the best performance at any load and handles line transients. Designed to power telecom and datacom applications, the converter handles input voltages from 36 to 75 V, delivering an output power of 420 W and 40 to 60-V inputs, with an output power up to 468 W. Output voltage can be adjusted from 4.0 to 13.2 V via PMBus commands. (From $46 ea/large qty — available now.)
