7 / 15 page Product # DQ62412QKA02 Phone 1-888-567-9596 Doc.# 005-2DQ245L Rev. A 06/08/05 Page 7 Figure 17: Max output power derating curves vs. air temp for 100 to 400 LFM, pin 3 to pin 1. 75% load (12A) on 1.225V output and 25% load (2A) on 2.45V output. At derating points, 1.225V output decreases while 2.45V output remains unchanged . Figure 18: Thermal plot of converter at 12 amp load on 1.225V output and 2 amp load on 2.45V output with 85°C air flowing at 200 LFM. Air flow across the converter is from pin 3 to pin 1 (nominal input voltage).
