Notes:

1. Exceeding the input range by a significant margin may damage the

units. For 24V input the input voltage should not exceed 40V; for 48V

models it should not exceed 80V.

2. Output accuracy for the negative output of dual output units is typically ±3% (±5% max.).

3. Output load regulation is specified for a load change of 10% to 100%. For 3.3V output units,

the load regulation is ±1.5% max.

4. When measuring output ripple, it is recommended that an external 0.33 µF ceramic capacitor

be placed from the +Vout pin to the -Vout pin for single output units and from each output to common

for dual output units.

5. These units should not be operated with a load under the specified minimum. Operation at

no-load will increase ripple significantly and may cause damage to the unit.

6. These converters are specified for operation without external components. However, in some

applications the addition of input/output capacitors will enhance stability and reduce output

ripple. Recommended capacitor values are:

Vin

For applications requiring very low output noise levels, a simple LC filter

should be effective.

7. 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.
