istics section provides a separate thermal resistance and
maximum junction temperature for both the control circuitry
and the power transistor. Calculate the maximum junction
temperature for both sections to ensure that both thermal
limits are met.
For example, look at using an FAN1582M-1.5 to generate
3A @ 1.5V ± 2% from a 3.3V source (3.2V to 3.6V).
Assumptions:
V

thermally conductive material)
The power dissipation in this application is:

= 70 + (6.39) * (5 + 3) = 121°C
The junction temperature is below the maximum rating.
Junction-to-case thermal resistance is specified from the IC
junction to the bottom of the case directly below the die. This
is the lowest resistance path for heat flow. Proper mounting
ensures the best thermal flow from this area of the package to
the heat sink. Use of a thermally conductive material at the
case-to-heat sink interface is recommended. Use a thermally
conductive spacer if the case of the device must be electri-
cally isolated and include its contribution to the total thermal
resistance.
