BXB75 Series

S i n g l e o u t p u t

DC/DC CONVERTERS 50-75W Wide Input DC/DC Converters

• Industry standard footprint

• MTBF >1.4 million hours (Bellcore 332)

• Input voltage to ETS300-132-2

• Adjustable output voltage

• No minimum load required

• Separate case ground pin

• 2:1 input range for battery powered applications

• Undervoltage lockout (UVLO)

• UL, VDE and CSA safety approvals

The BXB75 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 BXB75 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 BXB75 series is approved to IEC950 by UL, CSA and VDE.
