6.8 Typical Characteristics

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 1 through Figure 4.

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 devices soldered directly to a 50 mm × 100 mm double-sided PCB with 2 oz. copper. Applies to Figure 5 and Figure 6.
