Tool/software:
Is it possible to make a loop stability measurement with the fixed 1.2V output device (TPS628130AQWRWYRQ1) using the Network Analyzer technique described in the TI app note here? https://www.ti.com/lit/an/sluaai0/sluaai0.pdf?ts=1722925281692&ref_url=https%253A%252F%252Fwww.google.com%252F
Also, is the feed forward capacitor (Cff) present internally in the fixed 1.2V output device (TPS628130AQWRWYRQ1)? If not, does it need to be added?
