(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 6, Figure 7, and Figure 8.

(2)

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 modules soldered directly to a 100-mm × 100-mm, double-sided PCB with 2-oz. copper.

Applies to Figure 9.
