Other Parts Discussed in Thread: TPS546D24A
Hi TI team,
I'm using TPS546A24A in my design.
But when I measured PMbus i saw the periodic noise and I found that noise is synchronized with switching waveform. Please see the picture below ( the top is SCL signal and the bottom is measured at the output inductor)
Another image noise on SCL and SDA
I see that the noise is bigger when SDA and SCL is low state.
Please see our layout in below picture
Do you have any method to overcome this noise?
