Figure 18. Safe Operating Area
(1) The electrical characteristic data (Figure 10 through Figure 15) has been developed from actual products tested at 25°C. This data is
considered typical for the converter.
(2) The temperature derating curves (Figure 16 through Figure 18) 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.
