DC/DC Modules Slice Power Consumption, Boost Flexibility

With eyes on optimizing power performance and flexibility, the 3E BMR453 series isolated DC/DC converter delivers up to 400W or 33A of output in a quarter brick form factor. The module achieves this power density while providing a tight output-voltage regulation over an input voltage range of 36V to 75V at efficiency levels in excess of 96%. Reportedly, it’s the first DC/DC converter available to offer this combination of performance and power density. The second groups of 3E products, the BMR450 and BMR451, consist of digital POL regulators. The BMR450 features a wide input voltage range, making it easier to operate under most of the common intermediate bus voltages, i.e., 5V, 8V, and 12V. Output-voltage range is adjustable with an output current of 20A providing up to 100W of power. Efficiency is typically 96.8% at half load. The BMR451 is a digitally controlled, non-isolated voltage regulator rated at 40A. It offers a 4.5V to 14V input voltage range, 0.6V to 3.6V output voltage range, and a MTBF of 2.6 million hours.
