The external CTRL input can also be used to disable the converter by pulling the CTRL pin to ground. An internal pull-up current source allows an external
switch, open-collector transistor, open-drain transistor or a 3.3V/5V logic gate to be used to drive the CTRL pin. The UVLO adjust and external CTRL functions
can be combined.
