Hello

Could you review the attached design file? (SCH & PCB)

And how do you design to enhance EMI?

The order of the PCB layers is as follows.

Assembly Top : Top Slik, Assembly Bottom : Bottom Slik

Hi Louis,

there's quite a lot within the feedback loop of U8-A causing much phase lag. This could erode the phase margin of U8-A. Have you already carried out a phase stability analysis?

Many of the component values are not shown yet. Can you still add them?

Hi Kai

I did a phase stability analysis, but there is no problem.

I have attached a schematic showing the component values.

Best regards.
