Power Dissipation
The device power dissipation and proper sizing of the thermal plane that is connected to the thermal pad is critical to avoid thermal shutdown and
ensure reliable operation. Power dissipation of the device depends on input voltage and load conditions and can be calculated by:
P
D
= (V

The maximum power dissipation, handled by the device, depends on the junction to ambient thermal resistance, and maximum ambient
temperature, which can be calculated by the equation in the following:
