CSD95372BQ5M: CSD95372 and CSD95377Q4M / Waveform over the ABS-max

Guru 10545 points
Part Number: CSD95372BQ5M
Other Parts Discussed in Thread: CSD95377Q4M, TPS53661

Hello E2E,

Our customer is using the CSD95372BQ5M and CSD95377Q4M for now board.
They are evaluating it now.

SW-port voltage is over the absolut maximum range.
Please see the attached file.

SW-port voltage of CSD95372BQ5M down to -0.95-V at ON.
SW-port voltage of CSD95377Q4M down to -0.7-V at dead time.

Conditions;
  Contlorler is TPS53661.
  They referred CSD95377Q4M datasheet to layout design for both.

Questions;
  Does TI verified the parasitic inductance for this layout?
   -> Please provide this verified data.
  Can these devices accept the current situation?
   -> If can't there, please let me know the correctry layout.

Regards,
ACGUY
