Pin Function
Switching node — connect an inductor from the input supply to this pin.
Signal and power ground.
Battery or supply input — requires an external 10μF bypass capacitor (capacitance evalu-
ated while under V bias) for normal operation.
IN
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 5.0V.
Output voltage pin — requires an external 10μF bypass capacitor (capacitance evaluated
while under V bias) for normal operation.
OUT
Thermal Pad (MLPD package only) is for heat sinking purposes — connect to ground
plane using multiple vias — not connected internally.
