Pin n°

Symbol

Name

Pin function

Epad

Exposed pad

To be connected with power grounds and to the ground layer

through vias to dissipate the heat.

A-GND

Analog ground

Analog circuits ground.

BYP

By-pass capacitor

Needed for internal pre-regulator filtering. The BYP pin is

intended only to connect an external ceramic capacitor. Any

connection of this pin to external current or voltage sources

may cause permanent damage to the device.

ADDR

Address setting

Two I²C bus addresses available by setting the Address pin

level voltage. See address pin characteristics table.

ISEL

Current selection

The resistor “RSEL” connected between ISEL and GND defines

the linear regulator current limit threshold by the equation:

IMAX(typ.) = 10000 / RSEL.

Reserved

To be left floating. Do not connect to GND.

1, 2, 3, 7, 8,

16, 17, 23,

31, 32

N.C.

Not internally

connected

Not internally connected pins. These pins can be connected to

GND to improve thermal performances.
