(9) The electrical characteristic data has been developed from actual products tested at 25C. This data is considered typical for the
converter. Applies to Figure 1, Figure 2, and Figure 3.
(10) The temperature derating curves represent the conditions at which internal components are at or below the manufacturer's maximum
operating temperatures. The airflow direction is parallel to the long axis of the module. Derating limits apply to modules soldered directly
to a 100 mm x 100 mm double-sided PCB with 2 oz. copper. Applies to Figure 4.
