Figure 7-9. BD Mode Modualtion

7.4.8.2 1SPW Modulation

The 1SPW mode alters the normal modulation scheme in order to achieve higher efficiency with a slight penalty

in THD degradation and more attention required in the output filter selection. In Low Idle Current mode the

outputs operate at ~17% modulation during idle conditions. When an audio signal is applied one output will

decrease and one will increase. The decreasing output signal will quickly rail to GND at which point all the audio

modulation takes place through the rising output. The result is that only one output is switching during a majority

of the audio cycle. Efficiency is improved in this mode due to the reduction of switching losses.
