TPA3007D1 MODULATION SCHEME
SLOS418D – SEPTEMBER 2003 – REVISED MARCH 2008
Figure 14. Traditional Class-D Modulation Scheme's Output Voltage and Current Waveforms Into an
Inductive Load With No Input
The TPA3007D1 uses a modulation scheme that still has each output switching from ground to VCC. However,
OUTP and OUTN are now in phase with each other with no input. The duty cycle of OUTP is greater than 50%
and OUTN is less than 50% for positive output voltages. The duty cycle of OUTP is less than 50% and OUTN is
greater than 50% for negative output voltages. The voltage across the load is 0 V throughout most of the
switching period, greatly reducing the switching current, which reduces any I2R losses in the load. (See
