The FDC15 series offer 15 watts of output power from a 2 x 1.6 x 0.4 inch package. The
FDC15 series have 4:1 wide input voltage of 9-36 and 18-75VDC. The FDC15 features
1600VDC of isolation, short-circuit and over-voltage protection, as well as six sided
shielding. A safety approval to EN60950 and UL1950. All models are particularly suited to
telecommunications, industrial, mobile telecom and test equipment applications.

Note
1. The FDC15 series required a minimum 10% loading on the output to maintain specified
regulation. Operation under no-load condition will not damage these devices, however
they may not meet all listed specification.
2. Simulated source impedance of 12uH. 12uH inductor in series with +Vin.
3. The ON/OFF control voltage is reference to negative input.
4. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed
and controlled environment).
5. Heat-sink option, Thermal impedance is 8.24ºC/Watt for natural convection and the P/N
is 7G-0011A.
6. Maximum value at nominal input voltage and full load.
7. Typical value at nominal input voltage and full load.
8. Test by minimum Vin and constant resistor load.
