Notes
➀ Unless otherwise noted, all specifi cations apply over the full input voltage range, full temperature
range, nominal output voltage and full output load.
General conditions are near sea level altitude and natural convection airfl ow unless noted.
All models are tested and specifi ed with external parallel 1 µF and 10 µF output capacitors. A 470
µF input capacitor is used across the input pins.
All capacitors are low-ESR types mounted 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 specifi ed over 5 Hz to 20 MHz bandwidth. Input fi ltering is
Cbus = 220 µF, Cin = 33 µF and Lbus = 12 µH.
➂ All models are stable and regulate to specifi cation under no load.
➃ Reduction of Hazardous Substances (RoHS) compliance is to RoHS-6 (six substances restricted
including lead).
➄ Regulation specifi cations describe the output voltage changes as the line voltage or load current is
varied from its nominal or midpoint value to either extreme.
➅ The Remote On/Off Control is referred to -Vin.
➆ Please refer to the Part Number Structure for complete ordering model numbers.
