The NDM2Z family of digital PoL dc/dc modules deliver 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. The modules incorporate auto compensation, autonomously balancing the trade-offs between dynamic performance and system stability.
The digital PoLs target next-generation Information and Communication Technology (ICT) applications. They provide 91% efficiency at 12–Vdc in to 1.0–Vdc out, at 50% load. The modules are available with an input range from 4.5 to 14–Vdc and a programmable output range from 0.6 to 5.0–Vdc in the 12–A version and 0.6 to 3.3–Vdc in the 25– and 50–A versions. They feature 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 the GUI. (Engineering samples are available now.)
