nRF9160 - LDO VDD

[MJD093]

Hello,

We have finished the development of a prototype device that incorperates the nRF9160 SiP. I would like to know if there is anything I need to set-up in the device's configuration for the LDO driven power supply line.

I know from past experience with the nRF52832 chips that unless the line "CONFIG_BOARD_ENABLE_DCDC=n" was added to the defconfig file in the board device tree, the device would lock-up and the chip would no longer be detectable by JLink.

Does the nRF9160 require such a feature to be added to the board configuration files?

Hi,

 

No, the nRF9160 does not require anything like this, nRF9160 has one power mode only.

 

Best regards,

Andreas

Thanks Andreas, I was having a look back through the manual and saw the part on power supplies a few minutes ago:

That's my bad on that one, should have read the manual closer.

Thanks for the fast reply though
