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.
