Description
The new high performance 700W FBA48T25280 DC-DC converter provides a high efficiency single 28V output in
the fullbrick package. Specifically designed for operation in wireless systems that have limited airflow and
increased ambient temperatures, the FBA48T25280 converter utilizes the same pinout and functionality as the
industry-standard power amplifier bricks.
Operating from a 36-75V input, the FBA48T25280 converter provides a full regulated 28V output voltage that can
be trimmed from –40% to +15% of the nominal output voltage, thus providing outstanding design flexibility. The
open frame module is constructed with a dual board approach using the metal baseplate and discrete magnetics.
The standard feature set includes remote ON/OFF, differential output voltage sensing, input undervoltage lockout,
overtemperature, output overvoltage and overcurrent protections, current sharing, auxiliary voltage output, and the
Output Good signal.
With standard pinout and trim equations, the FBA48T25280 converter is a perfect solution for existing and new
designs. Inclusion of this converter in a design can result in significant power and cost savings. The designer can
expect reliability improvement over other available converters because of the FBA48T25280’s optimized thermal
efficiency.
