Note
1. The FKC08 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 on series with + Vin.
3. The ON/OFF control pin voltage is referenced to negative input.
4. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment)
5. Maximum value at nominal input voltage and full load of standard type.
6. Typical value at nominal input voltage and full load.
