Ben,

you are correct, we do not have a PMIC solution for DRA80x right now. Currently, there is only discrete solution for DRA80x (as seen on the EVM). At this time, I would recommend this discrete solution.

Feel free to contact me offline if your customer has specific requirements for their project.

Thanks,

Nastasha

Hi Nastasha,

We are looking for DC/DC regulator with Q grade for 0.9V-1.35V@3A core power, but we don't find it from TI.com.

Can we use other way to adjust output voltage instead of I2C? Like change feedback resistor value via GPIO?

Thanks!

Regards,

Ben
