CUI has introduced a line of regulated intermediate-bus DC-DC converters with advanced digital control from their Novum Advanced Power product line, a first product release based on the recently announced license agreement with Ericsson, for their Advanced Bus Converter portfolio based on the FRIDA II platform. The new converter family is available in two input range configurations; 40 to 60 V DC input for datacom applications and 36 to 75 V DC for telecom applications. The NEB 1/8 brick series is available with power ratings ranging from 264 to 300 W, while the NQB 1/4 brick series is available in 420 to 468 W configurations.   The output voltage for all models is preset at 12 V DC. For dynamic bus applications, however, users are able to dynamically adjust the NEB's output voltage through a PMBus interface from 6.9 to 13.2 V DC and the NQB's output voltage from 4.0 to 13.2 V DC.  For higher power needs, optional droop load sharing is offered in both series.   Additional features include insulation that meets EN60950 standards, 2.25 kV DC isolation voltage, and remote sensing. To address high-temperature applications, both series offer an optional baseplate for improved thermal performance. For conventional intermediate-bus converter requirements, the NEB and NQB series are available without digital communication pins in an industry standard five-pin package.  Samples are available now for digital and five-pin models.   CUI at Electronica 2012 in Munich will be located in hall B2 stand 518, showcasing their lineup of power supplies ranging from 1 W to 2.4 kW.
