Thermal management
In most applications the power dissipation in the IC is the main factor that sets the maximum
current that can be deliver by the device in a safe operating condition. Therefore, it has to be
taken into account very carefully. Besides the available space on the PCB, the right package
should be chosen considering the power dissipation. Heat sinking can be achieved using
to-ambient thermal resistance values for the PowerSO36, PowerDIP24 and SO24 packages.
For instance, using a PowerSO package with copper slug soldered on a 1.5 mm copper
thickness FR4 board with 6cm2 dissipating footprint (copper thickness of 35m), the RthJA is
about 35°C/W. Figure 20 shows mounting methods for this package. Using a multi-layer
board with vias to a ground plane, thermal impedance can be reduced down to 15°C/W.
