Ericsson has launched a new two-phase 90A 3E* digital point-of-load (POL) DC/DC power module that offers compensation-free performance and the ability to easily connect modules in parallel to provide up to 360A to advanced network-processors that require high performance in power delivery and high levels of software control to improve flexibility. These advanced capabilities make the BMR465 ready for future Software-Defined Power Architecture (SDPA) systems, which power system architects foresee as the way forward to achieving highly efficient and energy-optimized network architectures by 2020.
Patrick Le Fèvre, Marketing and Communication Director of Ericsson Power Modules, says: "The Software-Defined Power Architecture is being seen in the industry as the best way forward to optimize energy utilization in data networks and make them more energy efficient. The optimization of energy down to a granular level was at the origin of Ericsson’s digital power research, which was started in 2004. Now building upon a number of industry firsts in digital power, the BMR465 is the manifestation of our determination to support our customers today with technologies destined for the future. In addition, the BMR465 also complies with the new ‘teraAMP’ standard from the Architects of Modern Power (AMP) group of companies, which guarantees customers multiple sources of interoperable products."
The BMR465 POL converter can be operated as a standalone unit delivering 90A, as well as being part of a larger power system when processor boards require higher current. Built on a two-phase topology, four BMR465 modules can be connected in parallel together to deliver up to 360A. The BMR465 modules can become part of a multi-module and multiphase (up to eight-phase) power system that enables phase spreading, a reduction of peak current and also the amount of capacitors required by end systems. Designed to deliver cutting-edge performance, the BMR465 integrates ‘compensation-free’ modulation techniques, which automatically provide stability, accurate line and load regulation and good transient performance for a wide range of operating conditions. The non-linear charge mode control guarantees the control loop is always stable and the load step response within a single switching cycle conferring unprecedented stability while minimizing minimum filtering capacitors, saving both board space and cost.
