The high-density BMR683 converter is in the industry standard, quarter brick format to save board space. Output power is up to 500W at 28Vout, and the input range is 36V to 60V. Typical efficiency is up to 95.5% at full load (typical) and output voltage adjustment range is from 14V to 35V, which allows for optimisation of the connected RF section.
For RFPA applications using 28V GaN (gallium nitride) or laterally diffused MOSFET (LDMOS) PA designs, the high power converter provides a digital PMBus interface to allow easy monitoring of input and output voltages, output current, and device temperature. The device also allows users to configure many aspects of the device operation including voltage and current for improved fault tolerance and to optimise the module’s control loop for stable operation. Power management features also include configurable soft start/stop, precision delay, and ramp-up.
Protection functions include over-voltage, over-temperature and short-circuit protection mechanisms and mean time between failures (MTBF) is over five million hours (Mh).
The DC/DC converters comply with IEC/EN/UL 62368-1 safety standards and have an operational temperature range of -40°C to 125°C.
The industry-standard quarter brick DC/DC converter measures 58.4 x 36.8 x 12.7 mm (2.3 x 1.45 x 0.5 inches).
