Hi,
Do you have any guideline or information that express how to modify their DCDC circuit for loop stability measurement?
I have found following two articles from TI.com.

It's appreciated if you give me more ideas.
Background
My customer often ask us to measure the loop stability ( Phase and gain margin), because they have no equipment for it.
At my side, we can arrange some equipments, but sometime it's not easy to do modification on their board.
So I intend to ask customer to modify board (disconnect Vin and Vout, adding injection resistor and wiring out some necessary pins...) then ship to me.
Thank you for your support in advance.
Regards,
Ken
