When operating in extended input voltage range, the device will be fully functional but has a reduced performance specification on
certain parameters. An extended input voltage range is entered when the input voltage is dropping below 2.7 V, assuming the device is
not in undervoltage lockout mode.
When operating in Direct enable mode, the device will apply a default current setting. See
then be connected to GND.
