The derating factor is crucial for proper thermal performance. The higher the derating factor, the more power can be
dissipated from the device. Board layout affects the derating factor, and should be optimized to achieve the best thermal
performance. Using boards with large copper planes that are uncut by signal or power paths help tremendously. Using
heavier copper, 2 oz. as opposed to 1 oz., is also beneficial. Placing the device close to a fan is another way to enhance
thermal performance. Most importantly, the PowerPAD must be properly soldered down. Refer to the PowerPAD Thermally
Enhanced Package application note (SLMA002).
