Dear team,
I tested TPS40210 EVM but There is abnormal switching waveform. There is ringing at riging edge. And I also found simililar waveform at my customer board.
As changing external FET(TI CSD17577 or Vishay Sis412DN), the abnormal waveform is different. please review below waveform and let me know your opinion about reason of ringing and which specification of FET influence deeply switching waveform.
If you need schematic of customer or more information, please let me know your mail address.
Thank you.
