Power Switching Connection. Connect LX to the inductor and output rectifier. Connect components
as close to LX as possible.
Ground
Feedback Input. Connect a resistive voltage-divider from the output to FB to set the output voltage.
See the Setting the Output Voltage section.
Shutdown Input. Drive SHDN low to turn off the converter. To automatically start the converter,
connect SHDN to IN. Drive SHDN with a slew rate of 0.1V/µs or greater. Do not leave SHDN
unconnected. SHDN draws up to 50µA.
Soft-Start Input. Connect a soft-start capacitor from SS to GND to soft-start the converter. Leave SS
open to disable the soft-start function. See the Soft-Start section.
Internal Bias Voltage Input. Connect IN to the input voltage source. Bypass IN to GND with a
1µF or greater capacitor as close to IN as possible.
