Thermal management

In most applications the power dissipation in the IC is the main factor that sets the maximum

current that can be delivered by the device in a safe operating condition. Therefore, it must

be considered 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.
