Semiconductor junction temperature is
within 1°C of surface temperature
Figure 8: Thermal plot of converter at 15A load on 2.5V ouput and 15A
load on 3.3V output with 55°C air flowing at 200 LFM. Air flow across
the converter is from pin 1 to pin 3 (nominal input voltage).
Semiconductor junction temperature is
