Figure 9. Safe Operating Area
(1) The electrical characteristic data (Figure 1 through Figure 6) has been developed from actual products tested at 25°C. This data is
considered typical for the converter.
(2) The temperature derating curves (Figure 7 through Figure 9) 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. See the Safe Operating Area application section of this datasheet.
