Figure 5.
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.
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 4 in x 4 in double-sided PCB with 1 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 4,
and
Figure 5.
