(1)

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 13, Figure 14, and Figure 15.

(2)

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

Figure 14.

(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 16, Figure 17, and Figure 18.
