CXE15 Series Single output DC-DC CONVERTERS 10.8-15 W High Efficiency DC-DC Converters 1 * High efficiency topology, 87% typical at 5 V * Industry standard footprint * 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 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 Vdc to 75 Vdc and are available in output voltages of 5 V, 3.3 V, 2.5 V and 1.8 V. 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 5 V, 86% for the 3.3 V, 85% for the 2.5 V and 83% for the 1.8 V 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 2 A HRC 200 V 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 < 3 m 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. 11 This parameter is calculated at worst case line, load, temperature and initial settings.
