2:1 input range for battery powered applications
Undervoltage lockout (UVLO)
UL, VDE and CSA safety approvals
The BXB50 Series are high power density DC/DC converters packaged in the industry
standard footprint (2.40 x 2.28 x 0.50 inches) to give designers optimum choices when
specifying for both new and replacement designs. Suitable for a wide range of
applications in nearly any industry, the BXB50 was particularly designed with
communication and distributed power applications in mind. Using Bellcore 332, the
MTBF is greater than 1,400,000 hours. Aluminum baseplate technology with four
threaded M3 inserts makes heatsink attachment and optimum thermal management
easy. The BXB50 series are approved to IEC950 by UL, CSA and VDE.

PROTECTION
Measured with 10µF tantalum capacitor and 1µF ceramic capacitor across
output.
di/dt = 0.1A/1µs, Vin = 48VDC, Tc = 25°C, load change = 0.5 lo max. to
0.75 lo max. and 0.75 lo max. to 0.5 lo max.
Units should be characterised within systems. External components
required.
Input fusing is recommended based on surge current and maximum input
current.
This product is only for inclusion by professional installers within other
equipment and must not be operated as a stand alone product.
Simulated source impedance of 12µH. 12µH inductor in series with +Vin.
Active high remote on/off option is available (standard product is active
low), designate with the suffix ‘FHT’ e.g. BXB50-48S05FHT. Consult
factory for further details and options.
