Dear Specialists,
My customer is evaluating UCC28019A and has a question.
I would be grateful if you could advise.

We are evaluating UCC28019ADG4.
Noise is observed in VDS and VGS of Q1 and Q2 when the MOSFET is turned on.
Could you please attached excel file.
UCC28019ADG4_FET VDS_VG noise_20200930.xlsx
The waveforms are shown in Fig. 1 (when the load is ON) and Fig. 2 (when the load is on).
We confirmed that the gate signal is already noisy at Gate pin output (8pin) ,(Checked with TP20 in the circuit diagram)
Could you please let us know the cause and countermeasures for this noise?

I appreciate your great help in advance.
Best regards,
Shinichi
