DESCRIPTION
The TPA2013D1 is a high efficiency Class-D audio
power amplifier with an integrated boost converter. It
drives up to 2.7 W (10% THD+N) into a 4
speaker.
With 85% typical efficiency, the TPA2013D1 helps
extend battery life when playing audio.

2.7-W CONSTANT OUTPUT POWER CLASS-D AUDIO AMPLIFIER WITH INTEGRATED
BOOST CONVERTER
The built-in boost converter generates the voltage rail
for the Class-D amplifier. This provides a louder
audio output than a stand-alone amplifier connected
directly to the battery. It also maintains a consistent
loudness, regardless of battery voltage. Additionally,
the boost converter can be used to supply external
devices.
The TPA2013D1 has an integrated low pass filter to
improve RF rejection and reduce out-of-band noise,
increasing the signal to noise ratio (SNR). A built-in
PLL synchronizes the boost converter and Class-D
switching
frequencies,
frequencies and improving audio quality. All outputs
are fully protected against shorts to ground, power
supply, and output-to-output shorts.
