7.3.1 Undervoltage Lockout

An undervoltage lockout (UVLO) circuit stops the operation of the converter when the input voltage drops below the typical UVLO falling threshold of 2.26V. A hysteresis of 160mV is added so that the device cannot be enabled again until the input voltage goes up to typical UVLO rising threshold of 2.42V. This function is implemented in order to prevent malfunctioning of the device when the input voltage is between 2.24V and 2.42V.
