Part Number: TPS54202
Hi allWould you mind if we ask TPS54202?Our customer's condition are follows;<Condtions>Vin : 12VVout : 5VIout : 100mAOn the our customer's circuit, after start up, it occurs overshoot, Vout is more than 5.15 for an instant.Please refer to the attachment file.20180928_TPS54202.pdfSo, we would like to check it using TPS54202EVM, however we don't have this EVM.If you have the figure of start up with follow condtions, could you share it? Vin : 12VVout : 5VIout : 100mA
We would like to use this data to judge whether the the customer board has some problem or not.(We assume that the cause of a problem is parasitic inductance or pulse skip mode.)Kind regards,Hirotaka Matsumoto
The waveform is very strange, could you please share the schematic? Need to check whether there is problem on the schematic.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

Shawan sanThank you for your reply.We would like to the circuit and the layout using private messsage on E2E because the circuit and the layout contain confidential information.So, could you accept the request?Kind regards,Hirotaka Matsumoto
Shawan sanWe sent you circuit and layout using private message on E2E.Kind regards,Hirotaka Matsumoto
Shawn sanWe assume that your days are so busy, however could you give us the update?Kind regards,Hirotaka Matsumoto
In reply to Hirotaka Matsumoto:
Shawn sanThank you so much for our cooperation always!We encouraged the customer that there is no problem about TPS54202 EVM.So, we assume that the the problem depends on customer's constant and board layout. The customer accepted our suggestions.We appreciate your help!Kind regards,Hirotaka Matsumoto
