  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/G2e9F/100V, ESR 90m/G2d6. 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 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 minimum Vin and constant resistor load. 50 55 60 65 70 7536 4540 INPUT VOLTAGE (V) EFFICIENCY (%) FED20-48S1P5 Efficiency VS Input voltage 50 60 70 80 90 100 -40 -25 0 -10 100 AMBIENT TEMPERATURE (ºC) OUTPUT POWER (%) FED20-48S1P5 Derating Curve without Heat-Sink Nature Convection 50 60 70 80 90 100 -40 -25 0 -10 100 AMBIENT TEMPERATURE (ºC) OUTPUT POWER (%) FED20-48S1P5 (Note 5) Derating Curve with Heat-Sink 3 4 5 6 1 2 OUTPUT LOAD (A) EFFICIENCY (%) FED20-48S1P5 Efficiency VS Output load Nature Convection Output can be externally trimmed by using the method shown below.
