Hi

Before sending my board to production, I would like to get my designed reviewed.
I've attached the gerbers as well as the schematic here. Let me know if you need anything else from me.

Thanks in advance.

Pontus,

Schematic:

I have reviewed the schematic and the only comment that I have is that you only have a RC snubber (C14/R11) on the SW2 node and don't have footprints for one on the SW1 node. This is almost never necessary, but it can be helpful if you have issues passing EMC later in the design cycle. This is suggestion, not a requirement.

Layout:

C24 and C23 should be placed on opposite sides for the TPS25762CQ1. I cannot tell for sure where they are placed based on the gerbers, but I suspect that this is not the case from looking at the gerbers, I do not think that this has been done, but I cannot be sure because many of the parts to not have silk screen for me to trace the connection.

Regards,

Chuck

Hi.
Thanks for the reply.
The reference design PMP40934 has the snubber network on SW1 as NDP so I didn't bother adding it at all.
In retrospect, maybe i should've.

The C23 is places a bit to far from IC, I can see that now.

The C24 is place on the back PCB just under the TPS25762CQ1:

Is there anything else that looks wrong?
Would you like the Autodesk Eagle project files to be able to get a better look at it?
