Pin Function
Input Voltage: Connect a capacitor to ground to decouple the noise.
Switch (Output): Internal power MOSFET output switches.
Sense: Connect to V_OUT as close to output capacitor as possible to sense
output voltage.
Enable (Input): Logic high enables operation of the regulator. Logic low
will shut down the device. Do not leave floating.
Analog Ground: Connect to central ground point where all high current
paths meet (C_IN, C_OUT, PGND) for best operation.
Feedback (Input): Connect resistor divider at this node to set output
voltage. Resistors should be selected based on a nominal V_FB of 0.62V.
Power Ground.
Ground.
Connect to PGND or GND.
