The NDM2P series digital point-of-load converters operate with an input range of 4.5 to 14 VDC and a programmable output range of 0.6 to 3.3 VDC. They offer efficiencies above 93% at half load.

CUI has announced the release of its second-generation digital point-of-load DC-DC modules for distributed-power-architecture applications. The NDM2P series is the latest addition to CUI's Novum Advanced Power product line. The modules offer true cycle-by-cycle 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. With the NDM2P's self-compensation feature, the module is dynamically able to 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 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 X 0.500 X 0.286 in., a 25 A version measuring 1.01 x 0.54 x 0.32 in., and a 50 A version measuring 1.215 x 0.79 x 0.36 in. 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 to 14 VDC and a programmable output range of 0.6 to 3.3 VDC. Features include active current sharing, voltage sequencing, voltage tracking, synchronization and phase spreading, programmable soft start and stop, and a host of monitoring capabilities. All features are dynamically programmable via PMBus commands or a simple, easy to use GUI. "This is our second generation of fully-featured digital modules based on the Powervation technology," said Mark Adams, CUI's Senior Vice President. "The NDM2P is our highest performance family to date, targeting customers that value high efficiency and fast transient response in an extremely compact module design." The NDM2P series joins CUI's NDM2Z based on Intersil Zilker's self compensating digital controller. Engineering samples are available immediately for select customers. electronica 2012 CUI will exhibit at electronica in Munich from November 13 to 16. CUI will be located in the power hall B2 at stand 518 where they will showcase their lineup of power supplies ranging from 1 W to 2400 W, including advanced intermediate bus and digital point-of-load modules, medical AC-DC power supplies, and rugged industrial DC-DC converters.
