Hi,
I'm testing TPS54160, as you can see the image below, this is the Vsw waveform, and in the red circle is the voltage spike. i'm wondering what caused the voltage spike when mosfet switching?
I think current change so quickly at the switching moment, due to U=L*di/dt, U(voltage) will have a spike. am i correct?
if you have any suggestions, feel free to tell me.
Thanks.
Best regards
