The average efficiency is based on assumptions for a typical application with the power supply unit
operating at 25% of the nominal load during 25% of the time, 50% of the nominal load during 25% of the
time, 75% of the nominal load during 25% of the time and 100% of the nominal load during the remaining
time.
