Note

1. An external filter capacitor is required for normal operation. The capacitor should be
capable of handing 1A ripple current for 48V/24V models. Power mate suggest: Nippon
chemi-con KMF series, 220 F/100V, ESR 90m .
2.
Simulated source impedance of 12uH. 12uH inductor on series with +Vin.
3. The ON/OFF control function. There are positive logic (standard) and negative logic
(option). The pin voltage is referenced to negative input
To order negative logic ON/OFF control add the suffix-N (Ex: FED20-24S05-N)
4.
BELLCORE TR-NWT-000332. Case I: 50% Stress, Temperature at 40C. (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 minimum Vin and constant resistor load.
