TPS6594-Q1: SW waveform

Lijia Zhu

Part Number: TPS6594-Q1

Hi team,

Could you help to check if SW waveform below is as expected or not?

FPN is TPS65941213, we enable force muilt-phase(0x4 bit 2=1) in NVM. and sread spectrum is enabled by default.

Concern for waveform below is green pahse and yellow phase is overlap, is it ok?

Lijia,

I'm working to confirm that this behavior on the second switch node is as expected.

Hello Lijia,

this is expected at low current pulls.

Hi Nicholas,

It is measured at a 8A load currect. Is it as expected? Customer just told me this information. Sorry for this.

Lijia,

if they're not hitting any ILM errors, then it is fine.

My apologies on the late reply on this one.

BR,

Nicholas
