will the PMIC MC32PF3000A2EP support remote sense functionality?

Hi,

We are using PMIC MC32PF3000A2EP in our design with MCIMX7D3EVK10SD. Will the PMIC support remote sense functionality? If yes what is the ACL(Inductance) spec? Also let me know what are all the parameters should I check?

Thank you

Regards

Hi,

Thank s for the update.We are planning to use remote voltage sense for SW1A/B rails in PF3000 for the better regulation by connecting the SW1AFB from the load(CPU). We have followed the MCIMX7D-SABRE reference design. Just we wanted to confirm with you about this functionality. Please let us know your feedback.

Thanks for your feedback!

About FB pin should be connect with output capacitors together and not too long distance between load and PMIC SW1OUT.

So detail you can refer to the related reference design.

Hope this could help you!
