*) The average efficiency is an assumption for a typical application where the power supply is loaded with
25% of the nominal load for 25% of the time,
50% of the nominal load for another 25% of the time,
75% of the nominal load for another 25% of the time and with
100% of the nominal load for the rest of the time.
