Freescale Semiconductor

Thermal

Accurate thermal design requires thermal modeling of the application environment using computational

fluid dynamics software which can model both the conduction cooling and the convection cooling of the

air moving through the application. Simplified thermal models of the packages can be assembled using the

junction-to-case and junction-to-board thermal resistances listed in the thermal resistance table. More

detailed thermal models can be made available on request.
