1 / 5 page File Name: rfb300_350.pdf Rev: 03 Feb 2006 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25 °C unless otherwise stated. External output capacitance required (See Note 4) SPECIFICATIONS 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. • 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 24 Vin and 48 Vin single output International Safety Standard Approvals VDE0805/EN60950/IEC950 File No. 10401-3336-0198 Licence No. 40005395 UL/cUL CAN/CSA 22.2 No. 60950 UL 60950 File No. E135734 ABSOLUTE MAXIMUM RATINGS Input voltage - peak 24 Vin -0.5-50 Vdc (100 ms max., 48 Vin -0.5-100 Vdc 1.0 % duty cycle max.)
