TPS25983EVM: Internal layer of PCB

Shota Mago

Part Number: TPS25983EVM

Hi team,

The datasheet only shows top/bottom layers of PCB image. I think there should be internal layers because I can't find routing from ILIM, ITIMER pins etc. to headers(J9, J10 etc.). Also, GND plane of the IC looks floating.

Could you please provide PCB image of internal layers?

Best regards,

Hi Arush,

Thank you for providing the PCB image.

1st and 2nd images(Red) looks identical with top layer. I still can't find connection for GND for the IC.

Could you please provide image of GND layer?

Are 3rd and 4th images(Light blue) 2nd internal layer which is close to bottom side?

Best regards,

Red layer is top layer and light blue layer is power/signal layer. I added both in the word document cause initial connections from IC are on top layer and then they are on power/signal layer.

Ground layer is as follows:
