The THD+N measurements shown do not use an LC output filter, but do use a 100-
0.047-
F RC low-pass
filter with a cutoff frequency of ~30 kHz before the audio analyzer, so the switching frequency does not dominate
the measurement. This is done to ensure that the THD+N measured is just the audible THD+N. The THD+N
measurements are shown at the highest gain for worst case. The efficiency was measured with no filters and a
3-
, 4-, or 8- resistor in series with a 33-
H inductor as the load.
