Ericsson Digital Voltage Regulator wins Electronic Products China Award

“The BMR464 product represents a significant amount of teamwork worldwide, in design, development and marketing, and we all see this award as an important measure of success in our continuous efforts to deliver outstanding products to our customers, said Jianping Zheng, Head of Power Modules Sales and Marketing for Ericsson in Asia Pacific.

Ericsson Power Modules’ 3E series BMR464 is an addition to the company’s second-generation, digital point-of-load (POL) regulators. The device extends the maximum output current 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 devices are suitable for a wide range of applications including radio base stations, industrial automation, process control, transportation and large data centers. Ericsson’s intuitive graphic user interface for the PMBus makes power system configuration fast and simple.

The BMR464 is a small regulator measuring 30.85 x 20.0 x 8.2 mm (1.25 x 0.0787 x 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.

Ericsson was the first company to launch digitally controlled POL (point-of-load) regulators based on a digital core controller. Through close cooperation with board and systems’ designers, the company was the first to release a 21st century power architecture that can be fully integrated into the rest of the digital chain of processors and associated components.
