The FDC40 series offer 40 Watts of output power from a 3 x 2.6 x 0.4 inch package.
The FDC40 series have 2:1 wide input voltage of 9-18, 18-36 and 36-75VDC. The FDC40
features 1600VDC of isolation, short-circuit and over-voltage prot ection, as well as six
sided shielding. Designed meets the safety of EN60950 and UL1950. All models are
particularly suited to telecommunications, i ndust ri al, mobil e tel ecom and test equipment
applications.

Note

1. The FDC40 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. Cross regulation:
Dual output—Asymmetrical load 25% to 100% full load
Triple output – 3.3V / 5V 100% load and one of auxiliary 100% load, other
auxiliary load change from 25% to 100% load

3. Simulated source impedance of 12uH. 12uH inductor in series with +Vin.

4. The ON-OFF control pi n voltage is referenc e to negative input.

5. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC.

(Ground fixed and controlled environment)

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.
