2 Output derating against ambient
Following the previous design example, output derating against
ambient temperature can be determined by the following condi-
tions as shown in Fig.1-9 to 1-13. These value are for reference
only. Be sure to verify baseplate temperature is within output
derating as shown in Fig.1-1.for actual design-in
At this case, convection cooling means 0.2m/s air flows by
power module heating itself.
At vertical mounting Vin =48VDC
