TPSM13604H: Surface Heat Dissipation

Hi Team, Seeking your inputs. How can we determine the surface area needed for good heat dissipation?

Thank you.

    Hi Mark,

    You can refer to Section 10.2.1 for more information on thermal design. In that section there is a use case example that helps you calculate what the Rthteta_Ja_max value is and the resulting board area needed to be within that board thermal resistance. 

    Additionally in your PCB layer stackup, I'd suggest you use a 2oz|1oz|1oz|2oz copper thickness layer if you are designing a 4 layer board.

    Regards,

    Jimmy
