Hi Teams,

The buck2 output level is measured as 1.0 volt on our own IWR6843ISK based board

How to adjust parameters for buck2 output level up to 1.2 volt?

Regards,

Kevin

Hello Kevin,

On the IWR6843ISK Rev A/B boards used LP87702DRHBRQ1 power management device, which provides 1.24V, in the LP87702 KRHB output voltage expected to be 1.0V.

These are two different devices and have different power tree topologies, Please see below Technical reference manual for the detailed differences between the parts.

You may have to request the below PMIC part if you have used the IWR6843ISK reference design.
