AN557 APPLICATION NOTE
Figure 77.
Figure 78.
Fig. 78 shows the trend of the temperature as a function of the distance between two dissipating elements
whose dissipated power is fairly different (ratio 1 to 4). This graph may be useful in applications with two
devices in MTW package are synchronized.
