Doc ID 16261 Rev 3
, 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
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.

Inductor current in TM and L6563H THD optimizer
The following figures show the waveforms relevant to the inductor current at different voltage
mains. As visible in
mains. As visible in
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
is in phase with the input AC voltage, giving low distortion of the current waveform and high
