Bootstrap. This pin acts as the positive rail for the high-side switch’s gate driver. Con-
nect a 10nF between this pin and SW.
Input Supply. Bypass this pin to G with a low ESR capacitor. See Input Capacitor in Ap-
plication Information section.
Switch Output. Connect this pin to the switching end of the inductor.
Ground.
Feedback Input. The voltage at this pin is regulated to 1.222V. Connect to the resistor
divider between the output and ground to set output voltage.
Compensation Pin. See Compensation Techniques in Application Information section.
Enable Input. Drive higher than 1.3V or leave unconnected to enable the IC. Drive lower
than 0.7V to disable the IC. When disabled, the IC is in 6μA low current shutdown mode
and the output is discharged through the Low-Side Power Switch. This pin has a small
internal pull up current to a high level voltage when pin is not connected.
Not Connected.
