... THERMAL MANAGEMENT In most applications the power dissipation in the IC is the main factor that sets the maximum current that can be de- liver 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 ...
