SXE15 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 SXE15 is a new high efficiency open frame isolated 15 Watt converter series in an industry standard footprint. All 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 for the models are 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 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 SXE15 reduces compliance costs and time to market.

The SXE15 meets level A and level B conducted emissions only with external components connected before the input pins to the converter. See Application Note 116 for details. Recommended input fusing is a 2A HRC 200V rated fuse. This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. Measured with external Pi filter. See Application Note 116 for further details. Start-up into resistive load. Active low remote on/off is available. Standard product is active high. Designate with the Suffix ‘-R’ e.g. SXE15-48S05-R. Operating ambient temperatures are specified at natural convection. Higher operating temperatures are possible with increased airflow. See Application Note 116 for further details. SXE15-48S12 below 0.2A loading. OVP is TVS and 17V typical. Approvals pending for the SXE12-48S12. Signal line assumed < 3m in length. A 5% minimum load is required to maintain the output voltage regulation over all operating conditions for the SXE15-48S12. This parameter is calculated at worst case line, load, temperature and initial settings.
