The converter will shut down after the input voltage drops
below the under voltage protection threshold for
shutdown. The converter will start to work again after the
input voltage reaches the input under voltage protection
threshold for startup. For the Hysteresis, see the
Protection characteristics.

Output Overcurrent Protection
The converter equipped with current limiting circuitry can
provide protection from an output overload or short
circuit condition. If the output current exceeds the output
overcurrent protection set point , the converter enters
hiccup mode. When the fault condition is removed, the
converter will automatically restart.
