TPS5432: kindly do a detailed review for the buck section

Hi Aswin,

I am working on your request. Will provide a feedback later today.

Hi Aswin,

I reviewed the schematic and I do not see any major problems. However, I would like to clarify a few things.

- The additional ferrite bead on the output of the DCDC is not required as per the d/s. I would guess that this is a noise sensitive system and you need additional filtering. However, please be aware that this should not effect the loop stability of the DCDC. I suggest to confirm loop stability with your current BOM before actual implementation. 

- What is the max load? 

- What is your application?

-Is there any specific reason to choose TPS5432?

 What is the max load? 2A

What is your application? SUPPLY FOR SOC 

-Is there any specific reason to choose TPS5432? NO

Hi Aswin,

We have newer devices with better performance in our current portfolio. But the Fsw will be higher than 700kHz, What is the maximum switching frequency that is acceptable? Is there any particular reason to use a lower Fsw device?

Could you explain the Fco calculation used in your design? 

Regards,

Febin
