Notes
Unless otherwise noted, all specifi cations 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 airfl ow unless otherwise specifi ed. All models are tested and specifi ed with external
parallel 1 F and 10 F multi-layer output capacitors and a 22µf external input capacitor (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.
Input (back) ripple current is tested and specifi ed over 5 Hz to 20 MHz bandwidth. Input fi ltering is
Cin = 33 µF/100V, Cbus = 220µF/100V and Lbus = 12 µH.
All models are stable and regulate to specifi cation under no load.
The Remote On/Off Control is referred to -Vin.
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. The load step is ±25% of full load
current.
Output Ripple and Noise is measured with Cout = 1µF paralleled with 10µF, 20 MHz oscilloscope
bandwidth and full resistive load.
