An undervoltage protection is implemented to lock off the converter as long as the input voltage has not reached the UVLO turn-on threshold (see section 4 for value) which is the minimum input voltage required to operate without damaging the converter. > An overvoltage protection will inhibit the module when input voltage reaches the overvoltage lockout turn-off threshold (see section 4 for value) and restores to normal operation automatically when the input voltage drops below the overvoltage Lockout turn on threshold.
