EXB50 Series Single output DC/DC CONVERTERS 20-50W High Efficiency DC/DC Converters 1 NEW Product * High efficiency topology, 91% typical on EXB50-48S05 * Industry standard footprint * Wide operating temperature -40C to +70C (natural convection) * 60% to 110% output trim * No minimum load * Overvoltage and overtemperature protection * Remote sense compensation * Remote ON/OFF 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 24V input models with 5V, 3.3V and 2V outputs, and six 48V input models with 12V, 5V, 3.3V 2.5V, 2.0V and 1.8V outputs. All models feature a wide input range, trimmable output voltage and a 10A current rating (except the 12V). Remote sense and remote ON/OFF facilities are included as standard, and the converters are comprehensively protected against overcurrent, over-voltage and over-temperature conditions. 2 YEAR WARRANTY SPECIFICATIONS All specifications are typical at nominal input, full load at 25C 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.
