Could you please share the PVIN and VOUT noise waveform.
If the device is noise probably will be there is a sign for that noise on the Vout or PVIN waveforms.
Also what is the expecting loading condition for this device, if you can use the PMBUS dongle and use the GUI to read back the loading current it will be really helpful.
Hi Lim Wei Mei,
Good day to you too!
Thanks a lot for your clarification. We didn't receive from our customers that they encounter that mechanical noise issue before.
Maybe its related to a soldering issue between the board and the device, so in this case re flow the part can help to fix that issue.
