The converter has a built in soft start circuit. Rapidly changing the input voltage
from Vin(min) Vin(max) can bypass this circuit and damage the converter.

Application Notes chapter "MTBF"
Add a blocking diode to
Vout if current can flow
backwards into the out-
put, as this can damage
the converter.
