Other Parts Discussed in Thread: TPS65177
Now the customer is using BUF18830.
Below is the SCH.
When the picture displayed on the panel is changing, a ringing is observed as below.
Below is the waveform on OUTx pin. (The ringing amplitude is a little different from each other)
Below is the power rail of VS (powered by AVDD of TPS65177)
Could you please give some suggestion about that?
Thank you.
