DERATING OUTPUT POWER/CURRENT AND INPUT VOLTAGE
Temperatures are referenced to the temperature at the converter’s baseplate
Linearly derate output power/current from 100% at 85°C to 0% at 125°C.
Above 105°C linearly derate steady state input voltage to 33 V and
transient voltage to 38 V, at 125°C.
Operation below an input voltage of 19 volts, including operation in MIL-
STD-704E emergency power conditions, is possible with derated
output power. See Figures 9 and 10.
