BXB50 Series DC/DC CONVERTERS • • • • • • • • • Single output 33-50W Wide Input DC/DC Converters 1 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 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. 2 YEAR WARRANTY All specifications are typical at nominal input, full load at 25°C unless otherwise stated SPECIFICATIONS OUTPUT SPECIFICATIONS Voltage adjustability Set point accuracy Line regulation Load regulation Minimum load Overshoot Undershoot Ripple and noise (5Hz to 20MHz) (See Note 1) Temperature coefficient Transient response (See Note 2) Remote sense INPUT SPECIFICATIONS Input voltage range Input current Input current (max.)
