(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 1 , Figure 2 , and Figure 3 .
(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, 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 4 .
