The measured efficiency shown in 

, measured according to the ES-2 requirements, 

is very good at all load and line conditions. At full load it is always higher than 93% making 
this design suitable for high-efficiency power supplies. The average efficiency, calculated 
according to the ES-2 requirements, at different nominal mains voltages is shown in 

The measured output voltage at different line and static load conditions is shown in 

. As visible, the voltage is very stable over the entire input voltage and output load 

range.

The following figures show the waveforms relevant to the inductor current at different voltage 
mains. As visible in 

 and 

 the peak inductor current waveform over a line half-

period follows the MULT (pin #3) at both input mains voltages and therefore the line current 
is in phase with the input AC voltage, giving low distortion of the current waveform and high
