Tool/software:
Hello TI experts,
I'm charging 1S cells with the BQ25713EVM before doing my prototype, and I measured with the oscilloscope in AC mode. I observed ring noise due to the inductor and the MOSFETs. The frequencie of this noise is around 27.8 MHz and the Vpp is 152 mV. Is it possible to minimize it with a Pi filter, snubber circuit or EMI filter? Wihich one can you recommend me? I attached a capture of the plot below.
Also, I observed that this noise is different depending of the SOC, I want a more stable charge of my batteries for my project.
Thank you for your time,
Antonio López
