TPS61235P: PCB Layout Design Review

Hi Andy,

We will review it and give you review comments later. Thanks.

Great, eager to hear back as soon as possible.

Hi Andy,

Thanks for you reaching out. We have several suggestions about your layout:

1. you'd better use direct connection rather than cross connection when connect polygon pour with via or pad, because cross connection would increase parasitic inductance,

2. add more vias in GND polygon pour 

3. bold the line between 5VOUT, GND and USBC-OUT

And don't forget to add a GND polygon pour in bottom layer.

Best Regards,

Nathan

Hi Nathan,

I was a bit confused on your point #3. Could you explain further on what action to take?

And here's the updated schematic layout if you could take another look to see if everything is okay.

Thank you,

Andy

Here's another update on the layout. 

Thank you,

Hi Andy,

I mean it is better to bold the line in the blue cycle.

Nathan
