Pin Function

1

SS

Soft Start Pin.

2

EN

Enable pin. Logic high to enable the device.

3VIN

Supply voltage input. When VIN rises above the UVLO threshold and EN is logic high, the

device starts up.

4

GND

Power ground.

5

BST

Bootstrap. Requires a capacitor connected between LX and BST to form a floating supply

across the high-side switch driver.

6

VCC

Internal LDO output.

7COMP

External loop compensation pin. Connect a RC network between COMP and GND to com-

pensate the control loop.

8FB

Feedback input. The FB pin is used to set the output voltage via a resistive voltage divider

between the output and GND.

Exposed Pad

LX

Switching node. LX is the drain of the internal low-side power FETs.
