The module is capable of delivering a total of 140 A peak output at 0.5-1.3 V from an input of 4.5-16 V. Measuring 10 x 9 x 7.6 mm, the module provides a complete power stage, including magnetics, for a highly-specified voltage regulator 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 100 A, commonly found in the latest AI applications.
The halogen-free BMR510 has been optimised 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 now available.
The 2-phase BMR510 will be the first of many new VRMs 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.
