Package Thermal Characteristics
The VSC870 is packaged in a thermally-enhanced 21mm 192TBGA with an embedded heat sink. The heat sink
surface configurations are shown in the package drawings. With natural convection, the junction-to-case thermal
resistance is estimated to be 1.49
o
C/W. The approximate air flow versus thermal resistance relationship is shown in
Table 8. Refer to the application note AN-36 for thermal management and selection of heat sinks.
