9 Typical Characteristics (PVIN = 3.3 V, VIN = 5 V)
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 11, Figure 12, and Figure 13. 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 100-mm × 100-mm, 4-layer PCB with 2-oz. copper. Applies to Figure 14.
