Pin Function
Switching node — connect an inductor from the input supply to this pin.
Signal and power ground.
Battery input and damping switch connection.
Enable digital control input — active high.
Feedback input — connect to GND for preset 3.3V output. A voltage divider is connected from OUT to GND to
adjust output from 1.8V to 4.0V.
Output voltage supply pin — requires an external 10μF bypass capacitor (while under V
operation.
Thermal Pad is for heat sinking purposes — connect to ground using multiple vias — not connected internally.
