EXB50 Series Single output DC-DC CONVERTERS 20-50 W High Efficiency DC-DC Converters 1 • High efficiency topology, 91% typical on EXB50-48S05J • Industry standard footprint • Wide operating temperature -40 °C to +70 °C (natural convection) • 60% to 110% output trim • No minimum load • Overvoltage and overtemperature protection • Remote sense compensation • Remote ON/OFF • Available RoHS compliant The EXB50 series of 50 Watt single-output isolated dc-dc converters are specifically designed to meet the power needs of low-voltage silicon. Housed in an open-frame package with an industry-standard footprint, these latest-generation converters offer efficiencies as high as 91%. The series comprises three 24 V input models with 5 V, 3.3 V and 2 V outputs, and six 48 V input models with 12 V, 5 V, 3.3 V 2.5 V, 2 V and 1.8 V outputs. All models feature a wide input range, trimmable output voltage and a 10 A current rating (except the 12 V). Remote sense and remote ON/OFF facilities are included as standard, and the converters are comprehensively protected against overcurrent, overvoltage and overtemperature conditions. 2 YEAR WARRANTY SPECIFICATIONS All specifications are typical at nominal input, full load at 25 °C unless otherwise stated OUTPUT SPECIFICATIONS INPUT SPECIFICATIONS Continued Voltage adjustability 60% to 110% Setpoint accuracy Line regulation Low line to high line 0.1% max.
