300-350 W Half-Brick NEW Product DC-DC CONVERTERS * * * * * * * * 1 High efficiency topology Wide temperature range, -40 C to +100 C @ full power High power density (160 W/in3 in 0.4" tall version) Input voltage range: 18-36 Vdc or 36-75 Vdc Output voltage range: 7.2-13.2 Vdc or 16.8-29.4 Vdc Remote ON/OFF Operational insulation system Available RoHS compliant
RFB300/350 series is a high efficiency, enclosed, isolated dc-dc converter series in an industry standard half-brick package that provides up to 350 W of output power. The series delivers very high usable output power for today's high performance RF power amplifier and similar applications. The four models in the series feature an input voltage range of 18 Vdc to 36 Vdc and 36 Vdc to 75 Vdc and an output voltage of 12 V and 28 V. The output voltage is adjustable from 7.2 Vdc to 13.2 Vdc or 16.8 Vdc to 29.4 Vdc (not to exceed 308 W for the RFB300 [300 W for the RFB300-24S12] and 350 W for the RFB350). The series also has a remote ON/OFF capability. Overcurrent, overvoltage and overtemperature protection features are included as standard. Negative logic remote ON/OFF and other options are also available. Full international safety approval including EN/IEC60950 VDE and UL/cUL60950 reduces compliance costs and time to market.
All specifications are typical at nominal input, full load at 25 C unless otherwise stated.

Notes
Measurement Bandwidth: 20 MHz; Measured with 1 F ceramic and a 330 F (470 F for 12 V output model) aluminum or solid tantalum capacitor across the output terminals. 2 Di/dt = 1 A/s; Iout = 25% Iout (max); Vin = Vnom; Iout = Inom. Tested with a 1 F ceramic and a 330 F (470 F for 12 V output model) aluminum electrolytic capacitor across the output. 3 External input fusing required. Use a fast acting fuse: 40 A (24 V model), 15 A (48 V, 350 W model). 4 Iout = Iout (max) Measured with the input capacitor, Cbypass = 330 F, and 6 H inductor in series with the power source. Frequencies >100 kHz. 5 Signal line assumed <3 m in length. 6 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand-alone product. 7 Negative remote ON/OFF option also available. Add suffix `-R' to part number, for example see part numbering system. 8 With the enable signal asserted, this is the time from when the input current reaches 10 % of the final steady state value until the output voltage reaches 10 % of the nominal output value. Start-up into resistive load. 9 With Vin > Vin (min.) applied for a minimum of 1 second, this is the time from when the primary ON/OFF signal is activated until the output voltage reaches 10 % of the nominal output voltage. 10 Minimum effective ESR is 1 m. Minimum phase margin is 35. 11 Measured per ETSI 300 132-2 Section 4.7.2. 12 From 10% to 90% of Vout (nom). Full resistive load. 1 F ceramic and 330 F (470 F for 12 V model) electrolytic capacitors across the output. 1
