3.12 Thermal Performance
Figure 3-34 through Figure 3-37 show the temperature rise of the TPS543320 ICs at full 3-A load. Figure 3-34 and Figure 3-35 have only one TPS543320 on and loaded. Figure 3-36 and Figure 3-37 have both TPS543320s loaded. A minimum of a 10 minute soak time was used before taking each measurement.
