Notes:

1. When measuring output ripple, it is recommended that an external ceramic capacitor

(approx. 1 µF to 10 µF) be placed from the +Vout pin to the -Vout pin for single output

units and from each output to common for dual output units.

2. These units should not be operated with a load under 10% of full load. Operation at

no-load may cause damage to the unit.

3. These converters are specified for

operation without external compo-

nents. However, in some applica-

tions the addition of input/output

capacitors will enhance stability and

reduce output ripple. Recommended

capacitor values are given at right.

Output ripple on single output units

may be further enhanced by using

the CS terminal (single output units

operated at 50% load or below

should use this function). A low ESR capacitor is connected between the CS pin and the

-Vout pin (the capcitor anode connected to the -Vout pin). Recommended capacitor

values are given in the table at right. If not used, the CS pin should be left open.

4. Dual output units may be connected to provide a 10V, 24V or 30 VDC output. To do

this, connect the load across the +Vout and -Vout outputs and float the output com-

mon.

5. The remote on/off control pin is referenced to

the -Vin pin. Input current to the pin should

be between 5 - 10 mA with a maximum of 20

mA.

6. It is recommended that a fuse be used on the

input of a power supply for protection. See the Model Selection

table above for the correct rating.
