2. Transient recovery time is measured to within 1%
error band for a step change in output load of 75%
to 100%.
2,500
mW
Exceeding the absolute maximum ratings of the unit could cause damage.
These are not continuous operating ratings.
3. Ripple & Noise measurement bandwidth is 0-20
MHz.
4. These power converters require a minimum output
loading to maintain specified regulation.
5. Operation under no-load conditions will not
damage these modules; however, they may not
meet all specifications listed.
Environmental Specifications
6. All DC/DC converters should be externally fused at
the front end for protection.
