The BMR350 quarter-brick nonisolated dc/dc converter is rated at 860 W continuous and 1,200 W peak power. It is suitable as an intermediate bus converter for powering processors and ASICs with peak power demands. The product features an input of 40 to 60 V (80 V/100 ms) and a fully regulated output of 12 V at 100 A maximum, adjustable from 8 to 13.2 V. A transformer-coupled nonisolated topology reduces component count and current stress and yields an efficiency level peaking at > 97.8% at half load 48-V input voltage. For higher power levels, active current sharing between paralleled modules is an option.
