(1) The electrical characteristic data has been developed from actual products tested at 25C. This data is considered typical for the
converter. Applies to Figure 7 , Figure 8 , and Figure 9 .
(2) The temperature derating curves represent the conditions at which internal components are at or below the manufacturer ' s maximum
operating temperatures. Derating limits apply to modules soldered directly to a 100 mm x 100 mm double-sided PCB with 2 oz. copper.
For surface mount packages (AS and AZ suffix), multiple vias must be utilized. Please refer to the mechanical specification for more
information. Applies to Figure 10 .
