Notes ➀ Unless otherwise noted, all specifications apply at Vin = nominal, nominal output voltage and full output load. General conditions are near sea level altitude, no base plate installed and natural convection airflow unless otherwise specified. All models are tested and specified with external parallel 1 μF and 10 μF output capacitors (see Technical Notes). All capacitors are low-ESR types wired close to the converter. These capacitors are necessary for our test equipment and may not be needed in the user’s application. ➁ Input (back) ripple current is tested and specified over 5 Hz to 20 MHz bandwidth. Input filtering is Cin = 33 μF/100V, Cbus = 220μF/100V and Lbus = 12 μH. ➂ All models are stable and regulate to specification under no load. ➃ The Remote On/Off Control is referred to -Vin. ➄ Regulation specifications describe the output voltage changes as the line voltage or load current is varied from its nominal or midpoint value to either extreme. The load step is ±25% of full load current. ➅ Output Ripple and Noise is measured with Cout = 1 μF || 10 μF, 20 MHz oscilloscope bandwidth and full resistive load. |
