Note
1 Please add an external filter at converter input terminals when measuring input reflected ripple, as figure 1.
L: Simulated source impedance of 12μH C: Nippon chemi-con KMF series, 220μF/100V.
2 The ON/OFF control pin voltage is referenced to –Vin
3 BELLCORE TR-NWT-000332. Case I: 50%. Stress, Temperature at 40ºC. (Ground fixed and controlled environment)
4 An external filter capacitor is required for EMC testing. The capacitor should be capable of handing 1A ripple current for 48V models.
Power mate suggest: Nippon chemi-con KMF series, 220μF/100V, ESR 90mΩ.
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 resistive load.
