(1)
All data listed in Figure 5, Figure 6, and Figure 7 have been developed from actual products tested at 25
°C. This data is considered
typical data for the dc-dc converter.
(2)
The temperature derating curves represent operating conditions at which internal components are at or below manufacturer's maximum
rated operating temperature. Derating limits apply to modules soldered directly to a 100–mm
× 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 8.
