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

Efficiency and losses 1:
Efficiency over output current; losses over output current
