I/O DESCRIPTION
NAME NO.
EN 3 I This is the enable pin of the device. Pulling this pin to ground forces the device into shutdown mode.
Pulling this pin to Vin enables the device. This pin must be terminated.
FB 4 I This is the feedback pin of the device. Connect this pin directly to the output if the fixed output voltage
version is used. For the adjustable version, an external resistor divider is connected to this pin. The
internal voltage divider is disabled for the adjustable version.
GND 2 Ground
SW 5 I/O Connect the inductor to this pin. This pin is the switch pin and is connected to the internal MOSFET
switches.
