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
copper on the PCB with proper area and thickness. For instance, using a VFQFPN32L 5x5
package the typical R
a dissipating copper surface of 0.5 cm
through 18 via holes (9 below the IC).
