CUI Novum Intermediate Bus DC-DC converters now at Mouser

The CUI Novum Intermediate Bus NEB and NQB DC-DC Converters are offered in two input range configurations; 40 to 60V DC input for datacom applications, and 36 to 75V DC for telecom applications. The NQB series is housed in a quarter brick package and is available in 420Watt to 468Watt configurations. The NEB series is housed in an eighth brick package and is available in 264Watt to 300Watt configurations. Both series provide power efficiencies as high as 96.4 per cent, and optimised efficiency from 20 to 100 per cent.

These fully regulated DC-DC converters are managed by a 32-bit ARM microcontroller with energy-optimising firmware that insures peak performance across a wide range of power loads. The ARM firmware can detect and handle input voltage transients with slew-rates as fast as 0.5V/us while keeping the output voltage within +/-10 per cent. This prevents unwanted transients from triggering the module's over-voltage protection.

The output voltages for both the NEB and NQB series are initially set at 12V DC, and can be changed through the PMBus interface. The NEB series can be configured for output voltages from 6.9 to 13.2V DC, and 4.0 to 13.2V DC for the NQB series. For higher power requirements, an optional Droop Load Sharing supports connecting these Novum modules in parallel. The NEB and NQB series of devices target advanced power electronics systems where loading conditions can vary greatly, including next-generation telecom and Information and Communication Technology (ICT) equipment.
