Figure 2. Figure 3. TEMPERATURE DERATING TEMPERATURE DERATING vs vs OUTPUT CURRENT OUTPUT CURRENT Figure 4. Figure 5. (1) Characteristic data has been developed from actual products tested at 25 °C. This data is considered typical data for the converter. Applies to Figure 1, Figure 2, and Figure 3. (2) SOA graphs 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 inches × 4 inches 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.
