LMR38020: Regarding stability of LMR38020SDDAR in PFM mode.

Part Number: LMR38020

Hello Support,

I just made the design in Webench for VIN=15V, Vout=3.34V, Iout (max)=1A , Iout (min)=  50mA and using LMR38020SDDAR. Queries,

1. In operating values Webench doesn't shows phase margin when LMR38020 is in PFM mode, so how do we ensure that operating points are stable over complete load range?

2. How do we simulate the startup & transient conditions? Simulation doesn't seems to be available for this IC.
