CXE15 Series Single output DC/DC CONVERTERS 10.8-15W High Efficiency DC/DC Converters 1 * High efficiency topology, 87% typical at 5V * Industry standard footprint * Wide operating temperature, up to and exceeding 70C (natural convection) * 90% to 110% output trim * No minimum load * Overvoltage protection * Remote on/off control The CXE15 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 CXE15 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 CXE15 reduces compliance costs and time to market.

See Application Note 116 for details. 4 Recommended input fusing is a 2A HRC 200V rated fuse. 5 This product is only for inclusion by professional installers within other equipment and must not be operated as a stand alone product. 6 Measured with external filter. See Application Note 116 for details. 7 Start-up into resistive load. 8 Signal line assumed < 3m in length. 9 Operating ambient temperatures are specified at natural convection. Higher operating temperatures are possible with increased airflow. See Application Note 116 for details. 10 Remote ON/OFF (pin 3) and Trim (pin 5) are currently available individually or together by special order only. Manufacturing lead times may apply. The base model includes pins 1, 2, 4, and 6. Use the suffix `-R' for pin 3 with negative logic, `-S' for pin 3 with positive logic, and `-T' for the Trim pin. For example, a CXE 5V output with all six pins and positive remote ON/OFF logic should be ordered as `CXE15-48S05-ST'. 11 This parameter is calculated at worst case line, load, temperature and initial settings.
