Notes:
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.
3. PCB less than 130° C
