Bonjour, do you know about secorder sstems control theory, poles, zeros, and phase margin?
TI specs and app notes should give all info needed. Did you study it?
Suggest to use Use worst case design
Vin = min/max
Iout = min/max
For each of the 4 scenarios, calc load, R adj Vin, make bode plots and extract worst case phase margin.
Adjust compensation feedback to achieve a critical damped or overdamped response.
Normally change of the load capacitor is sufficient.
Faster to built it and test on the bench.
Bon chance
Jon
