Package Thermal Characteristics
The VSC880 is packaged in a thermally enhanced 31mm 304TBGA 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 0.45
o
C/W. The approximate air flow versus thermal resistance relationship is shown in
Table 12.3. Note: The VSC880 is not guaranteed to operate under cold start conditions. If the ambient temperature is
0
o
C, 15 seconds after power is applied, the case temperature will be at least 30
o
C, at which point it will be at thermal
equilibrium and ready for operation.
