Figure 91. Thermal Model
Figure 92 illustrates the case-to-ambient temperature (T_CA) in
relation to the power consumption (X-axis) and the thermal
resistance (Y-axis). If the power consumption and case
temperature are known, the thermal resistance (θ_CA)
requirement can be calculated for a given ambient temperature
(T_A) value.
