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 protection, as well as six
sided shielding. Designed meets the safety of EN60950 and UL1950. All models are
particularly suited to telecommunications, industrial, mobile telecom and test equipment
applications.

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.
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
Simulated source impedance of 12uH. 12uH inductor in series with +Vin.
The ON-OFF control pin voltage is reference to negative input.
BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC.
(Ground fixed and controlled environment)
Maximum value at nominal input voltage and full load
Typical value at nominal input voltage and full load

Sync
Application of synchronization
1. The unit is capable of external synchronization from an
independent time base with a switching rate between 200kHz
and 215kHz
2. The amplitude of the synchronizing pulse train is TTL
compatible
3. The duty cycle of the CLK should be 20% high and 80% low
4. Synchronization is referenced to negative input (-Vin)
