BQ24192: Getting the EMI peak

Part Number: BQ24192

Hello Team,

We have used the BQ24192 in our product.

Currently, we are doing the PTCRB test where we are failing the TIS test. We are suspecting that the battery charger might be a culprit here.

I have measured the switching frequency and found that there is ringing in the falling edge.

Here I am attaching the schematic and layout snapshot.

Sometimes I am also getting this type of switching waveforms.

Here is the EMI peak I am getting over the BQ24192.

let us know the suggestion to improve the EMI results.
