Notes:

1. When measuring output ripple & noise, it is recommended

that an external ceramic capacitor (approx

2. Transient recovery is measured to within a 1% error

band for a load step change of 25%.

3. Short circuit protection is provided by a “hiccup mode”

circuit.

4, These units should not be operated with a load under 5% of

full load. Operation at no-load will not damage the unit, but

they may not meet all specifications.

5. The recommended reflow settings are a peak temperature

gested temperature profile is shown on page four. For more

information, please contact the factory.

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.
