Second generation of digital POL modules dynamically set optimum stability in real time as conditions change

The NDM2P series is the latest addition to CUI’s Novum Advanced Power product line, which focuses solely on the design and development of leading edge power platforms. The modules offer true cycle-by-cycle compensation, autonomously balancing the trade-offs between dynamic performance and system stability.

With the 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. With the NDM2P’s self compensation feature, the module is able to dynamically set optimum stability in real time as conditions change.  With the addition of these second generation modules based on Powervation’s digital IC, CUI continues to be the only module manufacturer in the industry to offer a full portfolio of self compensating digital POL modules.

Offering efficiencies above 93% at half load, the NDM2P series is initially available in three compact DIP configurations; a 12 A version measuring 0.825 (L) X 0.500 (W) X 0.286 (H) in., a 25 A version measuring 1.01 x 0.54 x 0.32 inch, and a 50 A version measuring 1.215 x 0.79 x 0.36 inch SMT and SIP versions will be available as well. Additionally, to support dual layout needs, the modules are footprint nested.

The NDM2P series is available with an input range of 4.5~14 Vdc and a programmable output range of 0.6~3.3 Vdc. 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 a simple, easy to use GUI.

The NDM2P series joins CUI’s NDM2Z based on Intersil Zilker’s self compensating digital controller.

Engineering samples are available immediately for select customers.
