EXB250 Series Single output DC-DC CONVERTERS 72-165 W High Efficiency DC-DC Converters 1 • High efficiency topology, 90% typical at 3.3 V • Industry standard footprint • Wide baseplate temperature, -40 ˚C to +100 ˚C (natural convection) • 90% to 110% output trim • No minimum load • Overvoltage protection • Remote ON/OFF • Available RoHS compliant The EXB250 is a new high efficiency, open-frame, isolated 165 Watt converter series in an industry standard half-brick footprint. The EXB250 delivers very high output current at low voltages, and excellent useable power density for today’s high end applications. The design takes advantage of open frame construction to provide a low weight, low thermal impedance baseplate design. The seven models in the series feature an input voltage range of 33 Vdc to 75 Vdc and are available in output voltages of 12 V, 5 V, 3.3 V, 2.5 V, 1.8 V, 1.5 V and 1.2 V. The output voltage on each model is adjustable from 90% to 110% of the nominal value. Typical efficiencies for the models are 90% for the 3.3 V, 88% for the 2.5 V and 87% for the 1.8 V version. The EXB250 series also has a remote ON/OFF capability. Overcurrent and overvoltage protection features are included as standard. With full international safety approval including EN60950 (TÜV Rheinland) and UL/cUL1950, the EXB250 reduces compliance costs and time to market.
