2-phase integrated power stage up to 140 A peak
The BMR510 is a 2-phase integrated power stage which delivers a continuous total output current of 40 A per phase or 80 A total, and is capable of delivering a total peak output current of up to 140 A at an output voltage of 0.5-1.3 V. The input voltage range is 4.5-16 V, which makes it compatible with 4:1 conversion ratio front-end IBCs. The device delivers an efficiency of 90% at 13.5 V input / 0.8 V output / 40 A load.
At less than 0.7 cm3 (10 x 9 x 7.6 mm) 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 100 A, commonly found in the latest AI applications.
The halogen-free BMR510 is optimized for top-side cooling, and features LGA or optional 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.
