Notes:
1. Output load regulation is specified for a load change of 10% to 100%. Derating Curve
2. These units should not be operated with a load under 10% of full load. Operation
at no-load will not damage the unit, but they may not meet all specifications.
3. These converters will operate without external components. However, when
measuring output ripple,
it is recommended that an
Input Output
Vin Vout
external ceramic capacitor Capacitor Capacitor
be placed from the +Vout 5 VDC 4.7 µF 5 VDC 10.0 µF
pin to the -Vout pin for 12 VDC 2.2 µF 12 VDC 2.2 µF
single output units and from
each output to common for 24 VDC 1.0 µF 15 VDC 1.0 µF
dual output units. An input capacitor will enhance stability over temperature and
input line variations. Recommended capacitor values are given in the table above.
For applications requiring very low output noise levels, a simple LC filter should
be effective.
4. It is recommended that a fuse be used on the input of a power supply for protec-
tion. See the Model Selection table above for the correct rating.
