Notes:
1. Output load regulation is specified for a load change
Mechanical Dimensions
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 dam-
age to the unit.
3. These converters will operate without external com-
ponents. However, when measuring output ripple, it
is recommended that an external ceramic capacitor be
placed from the +Vout pin to the -Vout pin for single
output
units and Input Output

output to 5 VDC 4.7 µF 5 VDC 4.7 µF
common
12 VDC 2.2 µF 9 VDC 2.2 µF
for dual
output units. An input capaci- 12 VDC 1.0 µF
tor will enhance stability over 15 VDC 0.47 µF
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 effec-
tive.
4. Dual output units may be connected to provide a 10V,
18V, 24V or 30 VDC output. To do this, connect the
load across the positive (+Vout) and negative (-Vout)
outputs and float the output common
5. 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.
