DC/DC CONVERTERS 10.8-15W High Efficiency DC/DC Converters 1

2 YEAR WARRANTY

CXE15 Series

Single output

•High efficiency topology, 87% typical at 5V

•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 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.

All specifications are typical at nominal input, full load at 25°C unless otherwise stated

Notes

1Measured as per recommended set-up. See Application Note 116 for

details.

2di/dt = 0.1A/µs, Vin = 48VDC, Tc = 25°C, load change = 0.5 lo max. to 0.75

lo max. and 0.75 lo max. to 0.5 lo max.

3The CXE15 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.

4Recommended input fusing is a 2A HRC 200V rated fuse.

5This product is only for inclusion by professional installers within other

equipment and must not be operated as a stand alone product.

6Measured with external filter. See Application Note 116 for details.

7Start-up into resistive load.

8Signal line assumed < 3m in length.

9Operating 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.

CAUTION: Hazardous internal voltages and high temperatures.

Ensure that unit is not user accessible.
