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 15, Figure 16, and Figure 17.

(2)

At light load the output voltage ripple may increase due to pulse skipping. See Light-Load Behavior for more information. Applies to

Figure 16.

(3)

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, double-sided PCB with 1 oz.

copper. Applies to Figure 18, Figure 19, and Figure 20.
