Efficiency
The efficiency of the ISL6559EVAL2 board, loaded from 5 to
55A, is plotted in Figure 8. Measurements were performed at
room temperature and taken at thermal equilibrium with NO
AIR FLOW . The design exceeds the AMD Hammer Desktop
minimum requirements of 50% efficiency under minimum
loading and 80% efficiency at maximum loading even
without forced airflow. The maximum allowed airflow per the
