2.7-W CONSTANT OUTPUT POWER CLASS-D AUDIO AMPLIFIER WITH INTEGRATED
BOOST CONVERTER
• Cell Phones
• High Efficiency Integrated Boost Converter
(Over 90% Efficiency)
• PDA
• GPS
• 2.2-W into an 8- Ω Load from a 3.6-V Supply
• Portable Electronics
• 2.7-W into an 4- Ω Load from a 3.6-V Supply
• Operates from 1.8 V to 5.5 V
• Efficient Class-D Prolongs Battery Life
The TPA2013D1 is a high efficiency Class-D audio
• Independent Shutdown for Boost Converter
power amplifier with an integrated boost converter. It
and Class-D Amplifier
drives up to 2.7 W (10% THD+N) into a 4 Ω speaker.
• Differential Inputs Reduce RF Common Noise
With 85% typical efficiency, the TPA2013D1 helps
extend battery life when playing audio.
• Built-in INPUT Low Pass Filter Decreases RF
and Out of Band Noise Sensitivity
The built-in boost converter generates the voltage rail
• Synchronized Boost and Class-D Eliminates
for the Class-D amplifier. This provides a louder
Beat Frequencies audio output than a stand-alone amplifier connected
directly to the battery. It also maintains a consistent

loudness, regardless of battery voltage. Additionally,
• Available in 2.275 mm x 2.275 mm 16-ball
the boost converter can be used to supply external
WCSP and 4 mm x 4 mm 20-Lead QFN
devices.
Packages
The TPA2013D1 has an integrated low pass filter to
• 3 Selectable Gain Settings of 2 V/V, 6 V/V, and

increasing the signal to noise ratio (SNR). A built-in
PLL synchronizes the boost converter and Class-D
switching frequencies, thus eliminating beat
frequencies and improving audio quality. All outputs
are fully protected against shorts to ground, power
supply, and output-to-output shorts.
