Note
1. An external filter capacitor is required for normal operation. The capacitor should be capable of handing 1A ripple current for 48V 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 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. Test condition: nominal input and full load.
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.
