Pin Out Description
Pin
Name
Description
1
SDA
I2C Data Serial/Input/Output. Pull up to supply voltage with a 4.99k resistor.
2
PG
Power good output with open drain. If the output voltage is within regulation, the pull-up
resistor is required to indicate high.
3
EN
Enable pin. An input signal turns the regulator on or off. Connect EN to VIN through a
pull-up resistor. Do not float this pin.
4
SCL
I2C Clock. Pull up to supply voltage with a 4.99k resistor.
5
VOS
Output remote sense feedback.
6
ADDR
Address. Connect to AGND via a resistor to program I2C device address.
7
VOUT
Regulator output voltage. Place output capacitors between this pin and PGND.
8, 16
PGND
System ground. PGND is power ground of the power stage. Make the connection with
wide PCB traces.
9
AGND
Analog ground. Serves as the ground for internal reference and control circuitry.
10
VCC
Internal 5V LDO output. Supply power for the drive and control circuits.
11
VIN
Input voltage pin. Input for the internal LDO regulator.
12, 13,
14, 17
PVIN
Input voltage pin. Input for the internal MOSFETs.
15
SW
Test point for internal switch node. Connect to an isolated pad on the PCB.

Note 1. Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress
ratings only; functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliabilit.

1). JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process.
2). JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
