LM3445: After the input voltage is powered off, the pin voltage of LM3445 COFF will rise to more than 9V.

Hi Billy

I will need to check about this, do you have other information/waveform that can share?

Thanks and best regards.

Not yet.

Hi Billy

Let me check the schematic first, will reply to you soon.

Thanks

Hi Billy

Sorry for late reply. Currently didn't find issue in schematic.

Can you please share the waveform of VBUCK, ISNS during turn off?

Thanks and best regards.
