Ericsson Power Modules’ 3E series BMR464 is a new addition to the company’s second-generation, digital point-of-load (POL) regulators, that extends the maximum output current from such devices up to 40A. With unprecedented functionality, the regulator enables systems architects to fully monitor and dynamically control the energy that is delivered to processors, FPGAs, ASICs and other components, ensuring minimum energy consumption under all operating conditions. The BMR464 offers easy paralleling and current sharing. Up to seven modules can be paralleled, offering a maximum output current of 280A. The regulator’s easy-paralleling mode even makes it possible to combine its 20A counterpart, the BMR463, thus enabling ‘mix and match’ optimized efficiency from very low loads up to 60A. The devices are suitable for a wide range of applications including radio base stations, industrial automation, process control, transportation and large data centers. The BMR464 is a small regulator measuring 30.85 × 20.0 × 8.2 mm (1.25 × 0.0787 × 0.323 inches), so it can be used in compact systems with 15mm board pitch. The regulator accepts input voltages from 4.5V to 14V and has an output voltage range of 0.6V to 3.3V with typical efficiency of 97.2% at 5Vin, 3.3Vout and 50% load.
