Ericsson 3E digital voltage-regulators now support 93 PMBus commands to reduce energy consumption

More freedom for designers to dynamically optimize energy management
Increased efficiency with fewer components
Fully compliant with PMBus commands
Design simplified; time-to-market reduced
Based on digital-core controllers, the Ericsson 3E second generation of voltage regulators, the 12A BMR462, the 20A BMR463 and the 40A BMR464, now support 93 PMBus commands, allowing designers to monitor and control energy distribution from system level to board level.

The number of commands supported by the BMR462, BMR463 and BMR464, facilitate optimization of power-module configurations to varying load conditions. This minimizes power losses and reduces energy consumption by sending a command to automatically adjust the output voltage as the load changes; a lower voltage is optimal for low-load demand and a higher voltage as the load increases. It is also possible to shut down selected modules and reactivate them on-demand.

"Since Ericsson introduced its first digitally controlled voltage regulator November 2008, we have seen considerable increase of demand from system architects to optimize energy management to a very high degree. They are also motivated by the possibilities offered by PMBus and demand additional features that make it possible to fully integrate voltage regulators into their digital power management architecture," said Patrick Le Fèvre, marketing and communication director of Ericsson Power Modules. "That is exactly what our second generation of digital point-of-load is now offering, extending possibilities to an unprecedented level, saving cost, time-to-market and energy."
