Hi,

I am using TPS53315RGFT and TPS56628DDAR in my design. I want to use EMI/EMC shield for these regulator. Can you please suggest on what factors shield can be selected.

It is best to eliminate or minimize the source of the noise by following the layout guidelines in the datasheet.

SW node small, switching loops shorts, etc

The ideal shield is completely enclosed, but the power supply needs to dissipate power.

Also, the following papers from the power supply design seminar are helpful
