Hi Kevin,

I reviewed both rails. Please see my comments below:

1. For the 3.3V rail, there was not an inductor value listed. I recommend to select an inductor between 0.4uH-1uH.

2. For the 0.92V rail, everything looked good but there is some more room to add output capacitance to tune load transient performance. I recommend leaving some placeholder for capacitance to be added later (its value depends on derating), if transient spec is strict

Best regards,

Britton

Hi Britton,

Thanks for your feedback.

We are using 1uH for 3.3V rail.

Did you review our configuration file with respect to schematics?

If not, please review and share your feedback for that as well.

Thanks
Kevin
