Available output power depends on ambient temperature and good thermal management.

(See application graphs for limits.)

1. During short circuit, converter will shut down and attempt to restart once per second. The average current during this

condition will be very low and the device can be safely left in this condition continuously.

2. Limited by output energy storage. For improved performance see Tuned (T) model information.
