RFB300

The RFB300 series of isolated DC-DC converters is designed specifically to provide the main 12 V, 24 V or 28 V DC supply for RF power amplifiers in telecommunications applications.

The RFB300 series comprises three single output models, offering a choice of input/output voltage and output current ratings. The 12 V output model is capable of delivering up to 25 amps and accepts input voltages in the range 18 to 36 Vdc. Each of the other two models has a nominal 28 V output that can deliver up to 11 amps; one accepts input voltages from 18 to 36 Vdc, the other accommodates an input voltage range of 36 to 75 Vdc.

Rated at a nominal 300 watts, the converters can operate at full power with baseplate temperatures from -40 to 100˚C. The output of the 12 V model can be trimmed from 7.2 to 13.2 V, while the 28 V models can be trimmed from 16.8 to 29.4 V.

Based on a high power density design that incorporates a thermal baseplate, RFB300 series converters have an industry standard half-brick footprint and pin-out, with an installed height of just 0.5 inch (12.7 mm). They have a thermally optimized layout for conduction cooling and offer full load conversion efficiencies of up to 91%. Standard features include differential remote sense and remote On/Off, as well as comprehensive protection against overcurrent, overvoltage and overtemperature conditions.
