TPS92200D2EVM: How to evaluate the loop response

Dear TI team

 

I have a question related to the content of the thread below.

https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1217610/tps92200d2evm-about-the-value-of-rfb/4607448?tisearch=e2e-sitesearch&keymatch=%20user%3A449265#4607448

 

Please tell us how to evaluate the loop response with the EVM of this IC.

I am aware that I should evaluate by removing R7 (0Ω) on the EVM and instead populating R5 (49.9Ω) for signal injection. Is this perception correct?

We also recognize that there are multiple measurement methods (such as using FRA).

If you have detailed documentation or notes on evaluation, I would appreciate it if you could share them.

 

Best Regards,

Taroimo
