Notes: Derating Curve
1. Operation at no load will not damage these units. However, they may not meet all specifi cations.
2. These converters will operate without external components. However, when measuring output ripple, it is
recommended that an external capacitor be placed from the +Vout pin to the -Vout pin. An input capacitor
will enhance stability over temperature and input line variations. For applications requiring very low output
noise levels, a simple LC fi lter, as shown in the connection diagram below, should be effective. Recommended
component values are given in the table below the diagram.
3. Units that are specifi ed for momentary short circuit protection must be restarted after a fault.

3. 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.
