(1) The electrical characteristic data has been developed from actual products tested at 25 ° C. 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 × 100 mm double-sided PCB with 1 oz. copper.
Applies to Figure 10 , Figure 11 .
