Additional Notes:
1.
the converter‘s maximum allowable output power capability equal to the product of the nominal output voltage and the allowable output current
for the given conditions, the designer must, if necessary, decrease the maximum current (originally obtained from the derating curves) by the
same percentage to ensure the converter’s actual output power remains at or below the maximum allowable output power.
