(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) 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 (plated through holes) are required to add thermal paths around the power
pins. Please refer to the mechanical specification for more information. Applies to Figure 16 , and Figure 17 .
