PIN DESCRIPTION
Bootstrap. This pin acts as the positive rail for the high-side switch’s gate driver.
Connect a 10nF between this pin and SW.
Input Supply. Bypass this pin to G with a low ESR capacitor. See Input Capacitor in
Application 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 1.293V. Connect to the resistor
divider between output and ground to set output voltage.
Compensation Pin. See Compensation Technique in Application Information section.
Enable Input. When higher than 1.3V, this pin turns the IC on. When lower than 0.7V,
this pin turns the IC off. Output voltage is discharged when the IC is off. This pin has a
small internal pull up current to a high level voltage when pin is not connected. Do not
allow EN pin to exceed 6V.
Not Connected.
