(1) Characteristic data has been developed from actual products tested at 25 ° C. This data is considered typical data for the converter.
Applies to Figure 1 , Figure 2 , and Figure 3 .
(2) SOA 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. × 4 in. double-sided PCB with 1 oz. copper. Applies to
Figure 4 .
