Hi everyone,
Recently I decided the use `TPS55289` for our LED driving application.
However, when I checked the layout recommendation of the IC and also evaluation board `TPS552892EVM-111` I realized that there are copper keep outs underneath of the switching coil.
After I done searching about the copper filling under the coil in switching regulators, most studies are showing that GND filling underneath of the coil is much better for EMC performance.
I have confusion after I checked the TI's recommendation in the attachment.
Could you please enlighten me?
