(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 5 , Figure 6 , and Figure 7 .
(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 8 .
