Part Number: TPS543A26

Hi Team,

We are using the TPS543A26RYS Switcher part in our Layout Board file. I had attached the images of the Board file and Schematics. Please review the layout and share your feedback with us.

The PCB we are using is of 12 Layers:

IC - Place on top

Layers 2,4,9 and 11 are Ground

R189 is No mount.

Thanks and regards

- Teja.

    Teja,

    Place a 10 ohm resistor between C127/R161 and VCC_AFE_0V9 net.   So a frequency response of the loop can be tested. 

    R161 is a bigger package compared to R157, can you use the same size at R157. 

    Connect pin 16 and pin 17  to pin 5 and pin 8 on top level with a copper pour
