Note 1: Typical figures are at 25°C with a nominal 48V supply and are for design aid only. Not Guaranteed
2: The output ripple and noise can be reduced with an external filter, see application note.
3: Continuous short circuit duration is applicable at 25'C ambient temperature in free air. At higher temperatures
or with restricted airflow (e.g. in a sealed enclosure) the duration will need to be limited to avoid overheating
