Note
1. The FEC15 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 is option function. There are positive logic and negative logic. The pin
voltage is referenced to negative input
To order positive logic ON-OFF control add the suffix-P (Ex: FEC15-24S05-P)
T o order negative logic ON-OFF control add the suffix-N (Ex: FEC15-24S05-N)
4. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and
controlled environment)
5. Heat sink is optional and P/N: 7G-0020A
6. Maximum value at nominal input voltage and full load
7. Typical value at nominal input voltage and full load
8. Test by mini mum Vin and constant resistor load.
