Flex Power Modules BMR510 two-phase integrated power stage
Flex Power Modules is announcing the BMR510, its first two-phase integrated power stage, with a continuous total output current of 80A and capable of delivering a total of 140A peak output from 0.5V to 1.3V from an input from 4.5V to 16V.
At less than 0.7cm3 (10mm x 9mm x 7.6mm) the module provides a complete power stage, including magnetics, for a highly-specified module in space-constrained applications. Target end-use is to power silicon devices such as CPUs, GPUs, IPUs, high-end FPGAs and high-performing ASICs with a current demand of over 100A, commonly found in the latest AI applications.
The halogen-free BMR510 is optimized for top-side cooling, and features LGA or optionally solder-bump terminations for easy assembly. Over-temperature and over-current protection are included, and values are sensed for remote monitoring. An enable input is provided and the module will accept tri-state PWM inputs.
Thermal models are available for the part to enable effective integration in the target application. The BMR510 will be released for production in Q1/22 and samples are available now.
The 2-phase BMR510 will be the first of many new integrated power stages from Flex Power Modules. Future devices will offer different variations of total number of phases, available output current and footprints, to support both current and next generation CPUs and GPUs.
