Hi Sabrina,

Pardon me for the delay and thank you so much for the measurement
I do see some ringinng in the Vout. May I know if it will cause any instability?

Thanks

This is not ringing, the device is most likely operating in PFM, where you see the higher ripple. I don't expect this to cause stability issue.
