EN 4 3 I
This is the enable pin of the device. Pulling this pin to ground forces the device into shutdown
mode reducing the supply current to less than 1 μA. This pin should not be left floating and needs
to be terminated.
FB 3 4 I
This is the feedback pin of the device. Connect this pin to the external voltage divider to program
the desired output voltage.
GND 2 1 – Ground
NC – 5 – No connection
SW 1 6 I
Connect the inductor and the Schottky diode to this pin. This is the switch pin and is connected to
the drain of the internal power MOSFET.
