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 Vdc to 75 Vdc and are available in output voltages of 5 V/3.3 V and V/2.5 V. 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 5 V/3.3 V and 85% for the V/2.5 V 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.
All specifications are typical at nominal input, full load at 25 °C unless otherwise stated

4 The SXN15 features ‘Active High’ Remote ON/OFF as standard. An ‘Active Low’ Remote ON/OFF version is also available. To order the ‘Active Low’ version of the SXN15-48D05-3V3J please add the suffix ‘-R’ towards the end of the part number, i.e. SXN15-48D05-3V3-RJ. As part numbers cannot exceed 18 characters when ordering the ‘Active Low’ version of the SXN15-48D3V3-2V5J please add the suffix ‘R’ towards the end of the part number, i.e. SXN15-48D3V3-2V5RJ.
5 Operating ambient temperatures are specified at natural convection. Higher operating temperatures are possible with increased airflow. See Application Note 116 for further details.
6 Measured with external filter. See Application Note 116 for further details. 7 Signal line assumed < 3 m in length. 8 This parameter is calculated at worst case line, load, temperature and
initial conditions. 9 The ‘J’ suffix indicates that these parts are Pb-free RoHS 6/6 compliant.
TSE RoHS 5/6 non Pb-free compliant versions may be available on special request, please contact your local sales representative for details.
