SXN15 Series Dual positive output DC/DC CONVERTERS * * * * * * * * * * 15W High Efficiency DC/DC Converters 1 Two positive outputs Output voltage tracking High efficiency Approved to EN60950, UL/cUL1950 Wide operating temperature up to and exceeding 65C (natural convection) Up to 100% load imbalance Trim function No minimum load Complies with ETS 300 019-1-3/2-3 Fully compliant with ETS 300 386-1 The SXN15 is a new high efficiency open frame isolated 15 Watt converter series. The first two models in the series feature an input voltage range of 33 to 75VDC and are available in output voltages of 5V/3.3V and 3.3V/2.5V. The output voltage on each model is adjustable from 90% to 110% of the nominal value. Typical efficiencies for the models are 86% for the 5V/3.3V and 85% for the 3.3V/2.5V 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.
