TPS3852: flexibility in placing thermal pad vias

Part Number: TPS3852

My customer is having some manufacturing issues with placing vias underneath the body of the part and is asking whether the recommended vias could be either eliminated or moved away outside the perimeter of the footprint. 

Is the thermal pad function mainly for power dissipation or for noise immunity? Also, if the vias are eliminated (just like it would be in a single sided board) what are the risks?

Thank you!

  • Hi Lenio,

    Good talking to you again! :-) 

    There will be no risk if the vias are eliminated .  Will the GND pin connection to the thermal pad still be connected?  My belief is that the thermal pad or exposed pad is used to ensure the backside of the die is electrically connected to GND.
