No need for mount the heat sink on PCA9450,4-6 layers PCB can handle its power dissipation.

But the truth is , it put very near to the processor. so the team need to put Cooling on the whole area(CPU+PMIC+DDR..), so we need to consider the PMIC limit force of it. could you offer the related document?

I searched but no result for the heat sink related information for this HVQFN package.

We have the heat sink force spec on CSP package only.
