CUI sets efficiency benchmark, releasing auto-compensated digital PoL series in 2^nd-source footprint

CUI has announced a new family of digital PoL DC-DC modules that deliver over 95% peak efficiency in applications employing a distributed power architecture. The modules, available in 12-, 25-, and 50-A versions, are pin and function compatible with the 3E POL BMR46X series from Ericsson Power Modules, a division of Ericsson, which is the world's leading provider of technology and services to telecom operators. This compatibility enables OEMs to address interoperability challenges, reduce time to market, and decrease supply chain risk for these leading-edge digital POL products. The modules also incorporate auto compensation, autonomously balancing the trade-offs between dynamic performance and system stability. With this feature, designers are able to bypass the traditional practice of building-in margins to account for factors such as component ageing, manufacturing variations, and temperature, which inevitably lead to higher component cost and longer design cycles. The NDM2Z's auto compensation feature allows the module to set dynamically compensation for optimum stability in real time as conditions change. The NDM2Z series is the latest addition to CUI's Novum Advanced Power product line, which targets the most demanding next-generation ICT (information- and communication-technology) applications. Providing high efficiency, the NDM2Z 50-A module delivers 91% efficiency at 12 V DC in to 1.0 V DC out, 50% load. The family is available in three compact DIP configurations, a 12-A version measuring 0.827 x 0.500 x 0.284 in., a 25-A version measuring 1.01 x 0.54 x 0.284 in., and a 50-A version measuring 1.215 x 0.79 x 0.36 in. Horizontal SMT and vertical SIP versions are also available. For added flexibility during the development process, the horizontal DIP and SMT modules are footprint nested to accommodate dual layout needs as power requirements change. The modules are available with an input range of 4.5 to 14 V DC and a programmable output range of 0.6 to 5.0 V DC in the 12-A version and 0.6 to 3.3 V DC in the 25- and 50-A versions. Features include active current sharing, voltage sequencing, voltage tracking, synchronization and phase spreading, programmable soft start and stop, as well as a host of monitoring capabilities. All features are dynamically programmable via PMBus commands or through CUI's simple, easy to use GUI. The NDM2Z series is the first to be released by CUI as part of the cooperation with Ericsson announced in July 2011. The agreement formalizes a plan between the two companies to offer a multi-source digital POL platform based on the BMR46X series, with future plans to co-develop modules outside the existing range of 12 to 50 A.
