Introduction
This section provides an overview of the Texas Instruments (TI) TPA2080D1 audio power amplifier
evaluation module (EVM). It includes a brief description of the module and a list of specifications.
1.1
Description
The TPA2080D1 is a high-efficiency, class-D, audio power amplifier and an integrated boost converter. It
drives up to 2 W into a 4-Ω speaker from low supply voltages.
The TPA2080D1 audio power amplifier EVM is a complete, stand-alone audio amplifier. It contains the
TPA2080D1 WCSP (YZG) class-D audio power amplifier with an integrated boost converter. All
components and the EVM are Pb-free.

Operation
This section describes how to operate the TPA2080D1EVM.
2.1
Quick-Start List for Stand-Alone Operation
Use the following steps when operating the TPA2080D1EVM as a stand-alone or when connecting the
EVM into existing circuits or equipment.
2.1.1
Power and Ground
1. Ensure that the external power sources are set to OFF.
2. Set the power supply voltage between 2.3 V and 5.2 V. When connecting the power supply to the
EVM, attach the power supply ground connection to the GND connector first, and then connect the
positive supply to the VDD connector. Verify that correct connections are made to the banana jacks.
2.1.2
Audio
1. Ensure that the audio source is set to the minimum level.
2. Connect the audio source to the input RCA jack IN. In case of differential audio input, ensure that the
jumper, JP SE, is not inserted. In case of a single-ended audio input, ensure that the jumper, JP SE, is
inserted, thereby grounding IN+ through the input capacitor C2.
3. Connect a speaker (4 Ω to 32 Ω) to the output banana jacks, OUT+ and OUT–.
4. FLT OUT+ and FLT OUT- test points allow the user to connect the outputs of the amplifier through an
RC filter for audio measurements. (Many audio analyzers do not give the correct readings on a class-D
amplifier without additional filtering.) Note that the user must provide the necessary resistors, R7 and
R8, to complete the filters. The typical value for R7 and R8 is 1 kΩ.
5. The filtered output of the TPA2080D1 can be measured between test points FILT OUT– and FILT
OUT+
2.1.3
Amplifier Gain
The TPA2080D1 has a fixed setting of 20 dB.

Operation
www.ti.com
2.1.4
Shutdown Controls
1. The TPA2080D1 provides shutdown control for the class-D amplifier and the boost converter. The EN
pin enables the boost converter and class-D amplifier. It is active high.
2. Press and hold pushbutton S1 to place the boost converter and the class-D amplifier in shutdown.
Release pushbutton S1 to activate the class-D amplifier and boost converter. The boost converter only
turns on if an audio signal (> 2 VPEAK) is present at one of the outputs (OUT+ or OUT-).
NOTE: The TPA2080D1 has an auto passthrough mode. Under normal operation (EN = HIGH), the
boost converter automatically turns off if no audio signal is present at one of the inputs (IN+
or IN-).
2.2
Boost Settings
The default voltage for the boost converter is 5.9 V (unloaded) and cannot be changed. If no audio signal
is present, the boost converter is automatically disabled. Once the audio signal is present at IN+ and IN-,
the boost converter enables automatically, when the output signal exceeds 2 VPEAK.

Ripple current through the inductor.
Ripple voltage on PVOUT (PVDD) due to capacitance
Changing the Boost Inductor
Working inductance decreases as inductor current increases. If the drop in working inductance is severe
enough, it may cause the boost converter to become unstable, or cause the TPA2080D1 to reach its
current limit at a lower output power than expected. Inductor vendors specify currents at which inductor
values decrease by a specific percentage. This can vary by 10% to 35%. Inductance also is affected by dc
current and temperature.
Inductor current rating is determined by the requirements of the load. The inductance is determined by two
factors: the minimum value required for stability and the maximum ripple current permitted in the
application.
Use Equation 1 to determine the required current rating. Equation 1 shows the approximate relationship
between the average inductor current, IL, to the load current, load voltage, and input voltage (IPVDD,
PVOUT, and VBAT, respectively.) Insert IPVDD, PVDD, and VBAT into Equation 1 to solve for IL. The
inductor must maintain at least 90% of its initial inductance value at this current.

The minimum working inductance is 1.3 μH. A lower value may cause instability.

Ripple current, ΔIL, is peak-to-peak variation in inductor current. Smaller ripple current reduces core losses
in the inductor as well as the potential for EMI. Use Equation 2 to determine the value of the inductor, L.
Equation 2 shows the relationships among inductance L, VBAT, PVDD, the switching frequency, fboost, and
ΔIL. Insert the maximum acceptable ripple current into Equation 2 to solve for L.
VBAT ´ (PVDD - VBAT)
L=
ΔIL ´ fBOOST ´ PVDD
(2)
ΔIL is inversely proportional to L. Minimize ΔIL as much as is necessary for a specific application. Increase
the inductance to reduce the ripple current. Note that making the inductance too large prevents the boost
converter from responding to fast load changes properly. Typical inductor values for the TPA2080D1 are
2.2 μH to 4.7 μH.
Select an inductor with a small dc resistance, DCR. DCR reduces the output power due to the voltage
drop across the inductor.
2.2.3
Changing the Boost Capacitor
The value of the boost capacitor is determined by the minimum value of working capacitance required for
stability and the maximum voltage ripple allowed on PVOUT in the application. The minimum value of
working capacitance is 4.7 μF. Do not use any component with a working capacitance less than 4.7 μF.
Working capacitance is defined as the rated capacitance reduced by the dc bias factor, temperature, and
aging parameters of the capacitor being used. It may be necessary to request these parameters from the
capacitor manufacturer. For best performance, only consider ceramic capacitors with X5R or X7R
dielectric.
For X5R or X7R ceramic capacitors, Equation 3 shows the relationships among the boost capacitance, C,
to load current, load voltage, ripple voltage, input voltage, and switching frequency (IPVOUT, PVOUT, ΔV,
VDD, fboost, respectively). Insert the maximum allowed ripple voltage into Equation 3 to solve for C. A factor
of about 1.5 is included to account for capacitance loss due to dc voltage and temperature.
I
´ (PVDD - VBAT)
C = 1.5 ´ PVDD
D V ´ fBOOST ´ PVDD
(3)
For aluminum or tantalum capacitors, Equation 4 shows the relationships among the boost capacitance,
C, to load current, load voltage, ripple voltage, input voltage, and switching frequency (IPVOUT, PVOUT, ΔV,
VDD, fboost, respectively). Insert the maximum allowed ripple voltage into Equation 4 to solve for C. Solve
this equation assuming ESR is zero.
I
´ (PVDD - VBAT)
C = PVDD
D V ´ fBOOST ´ PVDD
(4)
Capacitance of aluminum and tantalum capacitors is normally insensitive to applied voltage, so no factor
of 1.5 is included in Equation 4. However, the ESR in aluminum and tantalum capacitors can be
significant. Choose an aluminum or tantalum capacitor with an ESR around 30 mΩ. For best performance
with tantalum capacitors, use at least a 10-V rating. Note that tantalum capacitors must generally be used
at voltages of half their ratings or less.
2.3
Power Up
1. Verify that the correct connections are as described in Section 2.1.
2. Verify that the voltage setting of the power supply is between 2.5 V and 5.2 V, and turn on the power
supply. Proper operation of the EVM begins.
3. Adjust the audio signal source as needed.
