Feedback sensing terminal for the output voltage. Connect this pin to the resistive divider of the output.
See Setting the Output Voltage section for more details.
Enable Input. EN is a digital input that turns the regulator on or off. Drive EN high to turn on the regulator and low
to turn it off. Attach to VIN or leave open for automatic startup. The EN has a precision threshold of 1.18V for
programing the UVLO. See Enable section for more details.
Power Input. VIN supplies the power to the IC, as well as the step-down converter switches. Drive VIN with a
3.8V to 32V power source. Bypass VIN to GND with a suitably large capacitor to eliminate noise due to the
switching of the IC. See Input Capacitor section for more details.
Power Ground.
Power Switching Output. SW is the switching node that supplies power to the output. Connect the output LC filter
from SW to the output load. Note that a capacitor is required from SW to BST to power the high-side switch.
High-Side Gate Drive Boost Input. BST supplies the drive for the high-side N-Channel MOSFET. A 100nF
capacitor is recommended from SW to BST to power the high-side switch.
