BQ25601: EVM test sw node waveform

Hi,team

I test the BQ25601 EVM board, I use Vin=5V battery=3.7V charging current=0.462A for fast charging mode.

the sw test point waveform shows me this, which looks weird. I followed by the EVM guidance setup.

    Hello Mona,

    I would suspect this to be related to the scope or probe used, it looks like either bandwidth limiting is enabled or your probe has high capacitance, a barrel tip probe is best for measuring switch node if possible.
