Descriptions

+ and - are terminals for connecting external load to

DA9231 Buck output; S+ and S- are kelvin sense

points for DA9231 Buck output.

Terminals for connecting external load to DA9231

LDO output.

DA9231 Input supply selection and voltage sense.

DA9231 input terminal (VDD_SYS_SL) can be

selected from 5V_USB or VDD_SYS_M of DA9070.

S+ and S- are kelvin sense points for DA9231 Buck

input.

Set IC_EN to VDD to automatically start the

DA9231 when VDD is applied. Set IC_EN to AGND

to completely disables the DA9231, including I2C

communication.

LDO input supply selection. LDO input terminal

VDD_LDO_SL can be selected from either DA9231

input VDD_SYS_SL or DA9231 Buck output

VO_BUCK_SL.

VDDIO voltage selection.

VDDIO can be connected from 4 options by

installing a jumper between VDDIO pin and the pin

next to its left: DA9070 Buck, DA9231 Buck,

DA9231 LDO, or independent 2.5V supply.

For evaluation purposes, the 2.5V supply position is

recommended to provide communications

regardless of which IC is enabled.
