Hello E2E,
I have a customer using the TPS54218 who is seeing some strange behavior on startup. When they increase Css to lengthen out the softsart time, they will see that the Vout ramp-up wont be linear. Instead, it looks as if there is no soft start at all (see generic image below). Have you noticed this before? Any suggestions to help rectify this?
Thank you very much!
Russell
