Pin Functions

PIN I/O DESCRIPTION
NAME WSON SOT
EN 4 3 IN This is the enable pin of the device. Pulling this pin to low forces the device into shutdown mode. Pulling this pin to high enables the device. This pin must be terminated.
FB 3 4 IN Feedback pin for the internal regulation loop. Connect the external resistor divider to this pin. In case of fixed output voltage option, connect this pin directly to the output capacitor
GND 6 2 PWR GND supply pin.
MODE 2 — IN This pin is only available at WSON package option. MODE pin = High forces the device to operate in fixed frequency PWM mode. MODE pin = Low enables the power save mode with automatic transition from PFM mode to fixed frequency PWM mode.
SW 1 5 OUT This is the switch pin and is connected to the internal MOSFET switches. Connect the external inductor between this terminal and the output capacitor.
VIN 5 1 PWR VIN power supply pin.
