Notes:
1. Output load regulation is specified for a load change of 10% to 100%.
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 will oper-
ate without external com- Input Output

ponents. However, when Capacitor Capacitor
measuring output ripple, 5 VDC 4.7 µF 5 VDC 10.0 µF
it is recommended that an
12 VDC 2.2 µF 9 VDC 4.7 µF
external ceramic capaci-
tor be placed from the 24 VDC 1.0 µF 12 VDC 2.2 µF
+Vout pin to the -Vout 15 VDC 1.0 µF
pin. An input capacitor 24 VDC 0.47 µF
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 Mechanical Dimensions
power supply for protection. See the Model Selection
table above for the correct rating.
