CUI – Latest digital PoL modules set optimum stability in real time as conditions changeSep 14 2012 - Power [More Power Articles]
CUI has announced the release of its second generation digital point of load (PoL) DC-DC modules for distributed power architecture applications.
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 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 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 12A version measuring 0.825 (L) X 0.5 (W) X 0.286 (H) inches, a 25A version measuring 1.01 x 0.54 x 0.32 in., and a 50A 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 14VDC 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, as well as 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.
“We believe that a multi-controller portfolio provides our customers with maximum flexibility for their specific needs. CUI is the first and only company to highlight to the digital power customer the need for interoperability consideration when choosing a company to partner with. All controllers are not the same, nor are our customer’s needs,” Adams concluded.More news from CUI
