(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 x 100 mm double-sided PCB with 2 oz. copper.

For surface mount packages (AS and AZ suffix), multiple vias must be utilized. Please refer to the mechanical specification for more

information. Applies to Figure 9.
