Notes

➀ Unless otherwise noted, all specifications are at nominal input voltage, nominal output

voltage and full load. General conditions are +25˚ Celsius ambient temperature, near

sea level altitude, natural convection airflow. All models are tested and specified with

external parallel 1 μF and 10 μF multi-layer ceramic output capacitors. The external

input capacitor is 4.7 μF ceramic. 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 Cbus=220 μF, Cin=33 μF 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.
