Pin Descriptions

Pin Num Pin

Descriptions

Bootstrap. This pin acts as the positive rail for the high-side switch’s gate driver.

Connect a 0.01uF capacitor between BS and SW.

Input Supply. Bypass this pin to GND with a low ESR capacitor. See Input Capacitor in

the Application Information section.

Vin

Switch Output. Connect this pin to the switching end of the inductor.

GND Ground.

Feedback Input. The voltage at this pin is regulated to 0.925V. Connect to the resistor

divider between output and ground to set output voltage.

COMP Compensation Pin. See Stability Compensation in the Application Information section.

Enable Input. When higher than 2.7V, this pin turns the IC on. When lower than 1.1V,

this pin turns the IC off. Output voltage is discharged when the IC is off. This pin should

not be left open. Recommend to put a 100KΩ pull up resistor to Vin for start up.

Soft-Start Control Input. SS controls the soft-start period. Connect a capacitor from SS

to GND to set the soft-start period. A 0.1uF capacitor sets the soft-start period to 15ms.

To disable the soft-start feature, leave SS unconnected.
