Application Note (cont.)

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:

PD = (VIN - VOUT) X IOUT

The maximum power dissipation, handled by the device,

depends on the maximum junction to ambient thermal

resistance, maximum ambient temperature, and

maximum device junction temperature, which can be

calculated by the following equation:

PD
