High Efficiency DC/DC Converters

SXE15 Single Series | 10.8 to 15W DC/DC High Efficiency DC/DC Converters SXE15 48V SERIES Single output High efficiency topology, 87% typical at 5V 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 SXE15 is a new high efficiency open frame isolated 15 Watt converter series in an industry standard footprint. The first five models in the series feature an input voltage range of 33 to 75VDC and are available in output voltages of 12V, 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 are 85% for 12V, 87% for the 5V, 86% for the 3.3V, 85% for the 2.5V and 12V and 83% for the 1.8V version. The SXE15 series has a remote on/off capability, with active 'HI' and active 'LO' options available. Overcurrent and [ 2 YEAR WARRANTY ] overvoltage protection features are included as standard. With full international safety approval including EN60950 and cUL1950, the SXE15 reduces compliance costs and time to market.
