Pin Function
1
2
PGND
VIN
Power ground. PGND needs to be electrically connected to AGND.
Supply voltage input. When VIN rises above the UVLO threshold and EN is logic high,
the device starts up.
3
AGND
FB
Analog ground. AGND is the reference point for controller section. AGND needs to be
electrically connected to PGND.
4
Feedback input. The FB pin is used to set the output voltage via a resistive voltage divider
between the output and AGND.
5
COMP
EN
External loop compensation pin. Connect a RC network between COMP and AGND to
compensate the control loop.
6
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.
7
PGOOD
LX (Sense)
LX
Power Good output. PGOOD is an open-drain output that indicates the status of output
voltage.
8
No Connect Pin. Pin 8 is not internally connected. Connect this pin externally to LX and
use it for better thermal performance.
Exposed pad
Switching node. LX is the drain of the internal PFET. LX is used as the thermal pad of the
power stage.
