CS52015−1
The value for RqJA is calculated using equation (3) and the
result can be substituted in equation (1).
The value for RqJC is 3.5°C/W for a given package type
based on an average die size. For a high current regulator
such as the CS52015−1 the majority of the heat is generated
in the power transistor section. The value for RqSA depends
on the heat sink type, while RqCS depends on factors such as
package type, heat sink interface (is an insulator and thermal
grease used?), and the contact area between the heat sink and
the package. Once these calculations are complete, the
maximum permissible value of RqJA can be calculated and
the proper heat sink selected. For further discussion on heat
sink selection, see application note “Thermal
Management,” document number AND8036/D, available
through the Literature Distribution Center or via our website
