CUI Inc. introduces 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 25 A and 50 A versions, are pin and function compatible in accordance to the Architects of Modern Power™ product standards. The 25 A module is microAMP™ compliant while the 50 A module complies with the megaAMP™ standard. This compatibility enables original equipment makers (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 aging, 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 dynamically set 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 Information and Communication Technology (ICT) applications. Providing best-in-class efficiency, the NDM2Z-50 module delivers 91% efficiency at 12 V_DC IN to 1.0 V_DC OUT, 50% load. The family is available in two compact DIP configurations, 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 4.5~14 V_DC and a programmable output range of 0.6~3.3 V_DC. 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.
