- TYPICAL CHARACTERISTICSThe electrical characteristic data has been developed from actual products tested at 25C. This data is considered typical for the converter. Applies to , , and .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 must be utilized. Please refer to the mechanical specification for more information. Applies to .
