Thermal Performance
This evaluation board is designed to operate with out
forced airflow as in an external printer power supply. The
thermal performance of the board is evaluated using an
infrared camera. Figures 40 through 43 show several images
of the board during a continuous load step as described in
Figure 1. Images include top and bottom layers at low and
high line. All images were taken in open air conditions
without forced airflow.
