Note
The FDC20 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 pin voltage is referenced to negative input
5. BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40ºC. (Ground fixed and controlled environment)
6. Heat sink is optional and P/N: 7G-0011A.
Operation temperature range please see curve.
7. Maximum value at nominal input voltage and full load.
8. Typical value at nominal input voltage and full load.
9. Test by minimum Vin and constant resistor load.
10. The FDC20-24D3305 and FDC20-48D3305 are safety approval pending.
