*) 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.

Efficiency and losses 1:
Efficiency over output current; losses over output current
Efficiency and losses 2:
Efficiency over input voltage; losses over input voltage
