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
Special Features
• 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
• 2 Year Warranty
international safety approval including EN/IEC60950 VDE and
UL/cUL60950 reduces compliance costs and time to market.

Notes
11 Measured per ETSI 300 132-2 Section 4.7.2.
1
Measurement Bandwidth: 20 MHz; Measured with 1 μF ceramic and a 330 μF
(470 μF for 12 V output model) aluminum or solid tantalum capacitor across
the output terminals.
12 From 10% to 90% of Vout (nom). Full resistive load. 1 μF ceramic and 330 μF
(470 μF for 12 V model) electrolytic capacitors across the output.
13 Converter guaranteed ON for positive option.
14 Maximum driver leakage to insure converter is ON.
15 Converter guaranteed OFF for positive option.

with a 1 μF ceramic and a 330 μF (470 μF for 12 V output model) aluminum
electrolytic capacitor across the output.
16 Driver sink current @ Vrc ≤ 1.2 V.

External input fusing required. Use a fast acting fuse: 40 A (24 V model), 15 A
(48 V, 350 W model).
Iout = Iout (max) Measured with the input capacitor, Cbypass = 330 μF, and 6
μH inductor in series with the power source. Frequencies >100 kHz.
Signal line assumed <3 m in length.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand-alone product.
Negative remote ON/OFF option also available. 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.
17 0.40 in height option is not available on the 12 V output model.
18 The’Y’ suffix indicates that these parts are TSE ToHS 5/6 (non-Pb-free)
compliant
19 New RoHS 6/6 codes coming soon: RFB300-48S28-R5J; RFB350-48S12-R5J.
