8.4.1 Operation With VIN< 4 V

The devices operate with input voltages above 4 V. The maximum UVLO voltage is 2.6 V and operates at input voltage above 4 V. The devices can also operate at lower input voltages; no minimum UVLO voltage is specified. At input voltages below the actual UVLO voltage, the devices do not operate.
