SXN15 Series Single output DC/DC CONVERTERS 10.8-15W High Efficiency DC/DC Converters 1 • 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 control The SXN15 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 SXN15 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 SXN15 reduces compliance costs and time to market.
