4.3.2 Thermal Results
Figure 4-8 through Figure 4-19 show the thermal captures of the system at full-load operation under various input voltage conditions. The soak-time was 30 minutes at an ambient temperature of 25°C. For mainboard images, Bx1 = LMG3624. For daughtercard images, Bx1 = SR controller, Bx2 = SR, Bx3 = diode bridge. For the top view images, Bx2, Bx3 = transformer.
