CXE15 Series Single output DC-DC CONVERTERS 15 W High Efficiency DC-DC Converters1 • High efficiency topology, 87% typical at 5 V • Industry standard footprint • Wide operating temperature, up to and exceeding 65 ˚C (natural convection) • 90% to 110% output trim • No minimum load • Overvoltage protection • Remote ON/OFF control • Available RoHS compliant The CXE15 is a new high efficiency open frame isolated 15 Watt converter series in an industry standard footprint. The CXE15 features an input voltage range of 33 Vdc to 75 Vdc and are available in output voltages of 5 V and 3.3 V. The output voltage on each model is adjustable from 90% to 110% of the nominal value. Typical efficiencies for the models are 87% for the 5 V and 86% for the 3.3 V. The CXE15 series also has a remote ON/OFF capability with active high or active low logic. Overcurrent and overvoltage protection features are included as standard. With full international safety approval including EN60950 and cUL1950, the CXE15 reduces compliance costs and time to market.
