Symbol

Name

Pin function

LX-A

N-Mos drain

Channel A, integrated N-channel Power MOSFET drain.

P-GND

Power ground

DC-DC converter power ground. To be connected directly to the

Epad.

LX-B

N-Mos drain

Channel B, integrated N-channel Power MOSFET drain.

ADDR

Address setting

Two I²C bus addresses available by setting the Address pin

level voltage. See the Address pin characteristics table.

SCL

Serial clock

Clock from I²C bus.

SDA

Serial data

Bi-directional data from/to I²C bus.

ISEL

Current selection for

both channel A and

The resistor “RSEL” connected between ISEL and GND defines

the linear regulator current limit threshold. Refer to “output

current limit selection”

Section 2. The RSEL resistor defines the

same current limit both for channels A and B.

GND

Analog ground

Analog circuits ground. To be connected directly to the Epad.
