TPS65131: TPS65131 stability margins

Maxime BONTHONNOU
Prodigy 10 points
Part Number: TPS65131

Hello,

I am contacting you regarding your component TPS65131.

I would like to understand and optimize the adjustment of the corrector in order to increase the stability margins of the converter. I saw on the datasheet that there are currently two ways to adjust the stability (the feedforward capacity on the Top resistance of the feedback and a specific capacitor which I assume to be that of zero of a type II corrector…) In order to eliminate any form of doubt, I would be grateful if you could porviding us with the internal structure of the controller and in particular the form (+ value) of the corrector internally? is it a type 2 (PI + HF filter)? Does the capacitor that we add to pins C+ and C- correspond to the zero of type 2?

Thanks for your answer.

Best regards.
