CS5208 ? 1
The maximum ambient temperature and the power
dissipation are determined by the design while the
maximum junction temperature and the thermal resistance
depend on the manufacturer and the package type. The
maximum power dissipation for a regulator is:
PD(max) + (VIN(max) * VOUT(min))IOUT(max) ) VIN(max) IIN(max)
A heat sink effectively increases the surface area of the
package to improve the flow of heat away from the IC and
into the surrounding air. Each material in the heat flow path
between the IC and the outside environment has a thermal
resistance. Like series electrical resistances, these
resistances are summed to determine the total thermal
resistance between the die junction and the surrounding air,
R Θ JC . This total thermal resistance is comprised of three
components. These resistive terms are measured from
junction to case (R Θ JC ), case to heat sink (R Θ CS ), and heat
sink to ambient air (R Θ SA ). The equation is:
R Q JA + R Q JC ) R Q CS ) R Q SA
R Θ JC is rated @ 1.4 ° C/W for the CS5208 ? 1. For a high
current regulator such as the CS5208 ? 1 the majority of heat
is generated in the power transistor section. The value for
R Θ SA depends on the heat sink type, while the R Θ CS 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 R Θ JA can be calculated and the proper heat sink selected.
