(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 1 and Figure 2 .
(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 4-in. x 4-in., double-sided, 4-layer PCB with 1-oz. copper.
See the mechanical specification for more information. Applies to Figure 3 and Figure 4 .
