Part Number: LM5046

Hi,

I would like to check the LM5046 WQFN28 layout guide, which has a thermal pad. Can LM5046 WQFN28 the AGND and PGND contact by thermal pad? Or need to follow the TSSOP? thanks.

Hello Rock,

I examined one of our LM5046 reference designs using the WQFN28 package. In that design they connected AGND and PGND to the thermal pad.

To see this, see Figure 14 in the following Application Note.
