Pin Function

1

PGND

Power ground. PGND needs to be electrically connected to AGND.

2

VIN

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

the device starts up.

3

AGND

Analog ground. AGND is the reference point for controller section. AGND needs to be

electrically connected to PGND.

4

VCC

Internal LDO output.

5

FB

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

between the output and AGND.

6

COMP

External loop compensation pin. Connect a RC network between COMP and AGND to

compensate the control loop.

7

LX

Switching node. LX is the drain of the internal power FETs.

8

EN

Enable pin. Pull EN to logic high to enable the device. Pull EN to logic low to disable the

device. If on/off control in not needed, connect EN to VIN and do not leave it open.
