PIN I/O DESCRIPTION
NAME DDC,
DBV NO.		 DRV NO.
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.
VIN 5 2 I Supply voltage pin
- ThermalPAD - Solder to ground plane for heat sink
