High efficiency topology, 87% typical at 5V Industry standard footprint Wide operating temperature, up to and exceeding +70˚C (natural convection) 90% to 110% output trim No minimum load Overvoltage protection Remote on/off Approvals to EN60950 and UL/cUL1950 Complies with ETS 300 019-1-3/2-3 Complies with ETS 300 132-2 (input voltage and current requirements) Complies with ETS 300 386-1 The CXE15 is a new high efficiency open frame isolated 15 Watt converter series in an industry standard footprint. The first four models in the series feature an input voltage range of 33 to 75VDC and are available in output voltages of 5V, 3.3V, 2.5V and 1.8V. 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 5V, 86% for the 3.3V, 85% for the 2.5V and 83% for the 1.8V version. The CXE15 series also has a remote on/off capability, with active 'HI' or active 'LO' logic options available. 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.
