5.3 Thermal Performance

Figure 5-3 shows the thermal image.

Figure 5-3 Thermal Image VIN = 3 V IOUT = 0.6 A, VBIAS = VIN, no Forced Air Cooling
Figure 5-5 Thermal Image VIN = 6 V IOUT = 1.6 A, VBIAS = VIN, no Forced Air Cooling
Figure 5-4 Thermal Image VIN = 3 V IOUT = 0.6 A, VBIAS = 12 V, no Forced Air Cooling
Figure 5-6 Thermal Image VIN = 9 V IOUT = 1.6 A, VBIAS = VIN, no Forced Air Cooling
