New 25A regulator offers very high power density of 28.44W/cm3 (465W/in3) and 25 percent more output current in the same footprint as second-generation 20A module. Dynamic Loop Compensation improves stability and shortens time-to-market. Paralleling of seven modules with phase spreading delivers 175A, while ripple-and-noise is reduced to the lowest possible level.

The new Ericsson 3E series BMR463-25A is a third-generation digital point-of-load (POL) regulator that features Dynamic Loop Compensation (DLC) and delivers a 25percent increase in output current over the second-generation BMR463-20A, yet comes in a fully compatible footprint. The product features a full set of PMBus commands enabling systems architects to fully monitor and dynamically control the energy delivered to strategic components, such as processors, FPGAs, ASICs and others, down to a very low and highly economical level.

Embedding the latest technology in terms of Dynamic Loop Compensation, the BMR463-25A runs the DLC algorithm as default each time the output is enabled. However, three more settings are also available via the PMBus for systems architects to choose the most appropriate method for their application with the DLC algorithm run every second or every minute or simply disabled. In addition to standard methods, designers can also use the Loop Compensation Tool featured in the latest Ericsson Power Designer software to set their own loop compensation profile to match specific application requirements.

Patrick Le Fèvre, Marketing and Communication Director, Ericsson Power Modules, says: "The second generation of Ericsson 3E POL regulators were introduced in February 2011 and rapidly became the reference digital point-of-load devices and gained impressive market adoption. The third generation results from very close cooperation with systems architects that require additional flexibility and simplicity, while also retaining the ability to control parameters to match specific applications. Following the recently released 12x12 12A BMR461, the BMR463-25A now offers Dynamic Loop Compensation to volume markets that are demanding this type of product."
