TPS62827: layout guide questions

Jamie Tseng

Part Number: TPS62827

Hi team,

1. Could you kindly provide the layout guide of the layer under inductance (LX) that should be empty or ground? Or any special pattern?

2. How to evaluate the change in inductance due to the layout of the PCB?

The customer has 8 layers in their design.

Thanks for your kindly help!

Hi Jamie,

You can find our recommended layout for the TPS62827 in the following document: TPS62827EVM.

This EVM has 4 layers, using 8 layers will not be an issue. Commonly under inductor, you may find ground plane to reduce noises impacts induced by switching behavior of DC/DC converter.

I am not sure to understand your second question here, can you explain what is your concern to be addressed here?

Thank you very much!

Best Regards,

Dorian
