Pin Name

Pin Function

Switching node — connect an inductor from the input supply to this pin.

GND

Signal and power ground.

Battery or supply input — requires an external 10μF bypass capacitor (capacitance evalu-

ated while under V

bias) for normal operation.

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.

OUT

Output voltage pin — requires an external 10μF bypass capacitor (capacitance evaluated

while under V

OUT

bias) for normal operation.

TNA

Thermal

Pad

Thermal Pad (MLPD package only) is for heat sinking purposes — connect to ground

plane using multiple vias — not connected internally.
