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 operate without external components. However, when measuring out-
put ripple, it is recommended that

be placed from the +Vout pin to

Tested on X, Y & Z axis for 60 minutes.
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.
