RFB300/350 Series 24Vin and 48Vin single output DC/DC CONVERTERS * * * * * * * 308W and 350W Half brick 1 NEW Product High efficiency topology Wide temperature range, -40C to +100C @ full power High power density (160W/in3 in 0.4" tall version) Input voltage range: 18V to 36V or 36V to 75V Output voltage range: 7.2V to 13.2V or 16.8V to 29.4V Remote ON/OFF Operational insulation system RFB300/350 series is a high efficiency, enclosed, isolated DC/DC converter series in an industry standard half brick package that provides up to 350W 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 to 36VDC and 36 to 75VDC and an output voltage of 12V and 28V. The output voltage is adjustable from 7.2V to 13.2V or 16.8V to 29.4V (not to exceed 308W for the RFB300 and 350W for the RFB350). The series also has a remote ON/OFF capability. Over current, over voltage and over temperature 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. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25C unless otherwise stated.

Add suffix `-R' to part number, for example see part numbering system. 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. 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.
