3.2 PWM Frequency Adjust
The TPA3223EVM allows for three oscillator frequency options by external configuration of the FREQ_ADJ pin.
The frequency adjust can be used to reduce interference problems while using a radio receiver tuned within the
AM band. These values must be chosen so that the nominal and the lower value switching frequencies together
results in the fewest cases of interference throughout the AM band. The oscillator frequency can be selected by
the value of the FREQ_ADJ resistor connected to GND in Primary mode according to Table 3-2.

Resistor Selected to GND or Pullup
Primary MODE
10 kΩ
Primary MODE AM1
30 kΩ
Primary MODE AM2
49.9 kΩ
Peripheral MODE
Pullup to 5 V
Selecting Peripheral Mode configures the OSC_I/O pins as inputs to be synchronized from an external
differential clock. In a Primary or Peripheral system, interchannel delay is automatically set up between the
switching phases of the audio channels, which can be illustrated by no idle channels switching at the same
time. The audio output will not be influenced, but the switch timing is changed to minimize noise coupling
between audio channels through the power supply. This configuration will optimize audio performance and result
in better operating conditions for the power supply. The inter-channel delay will be set up for a peripheral device
depending on the polarity of the OSC_I/O connection such that peripheral mode 1 (secondary) is selected by
connecting the OSC_I/O of the Primary device with the OSC_I/O of the peripheral device with the same polarity
(+ to + and – to –), while peripheral mode 2 (tertiary) is selected by connecting the OSC_I/Os with the inverse
polarity (+ to – and – to +).

Hardware Configuration
3.3 Modulation Modes (AD Mode and HEAD Mode)
The TPA3223EVM supports both AD modulation as well as HEAD modulation. In AD mode, each of the two
half-bridge outputs are continuously switching. AD mode is the default mode for the TPA3223EVM. The EVM
also supports HEAD mode modulation. HEAD mode also switches both half bridge outputs but also optimizes
the switching for lower power loss at idle as well as increased EMI performance at cost of some performance.
The device accomplishes this by reducing its duty cycle at idle and while playing small signals. At higher output
levels HEAD mode will also reduce the switching on one of the half bridges. The modulation mode can be
controlled through jumper J6 on the EVM as follows:
Table 3-3. HEAD and AD Mode Selection
J6 Jumper State
Modulation Mode
IN
AD Mode
OUT
HEAD Mode
More information on the differences between HEAD mode and AD mode as well as performance data is found in
the TPA3223 data sheet (SLASEF0).
3.4 Output Mode Selection
The TPA3223 does not use discrete mode pins and therefore relies solely on the states of the IN2_M and IN2_P
pins. Connecting the IN2_M and IN2_P pins to regular high output impedance audio outputs by removing J7
and J8 puts the TPA3223 into BTL mode (2 x stereo outputs). Tying the IN2_M and IN2_P pins to GND by
installing J7 and J8 on pins 2-3 puts the TPA3223 into PBTL mode (1 x mono output). Tying the IN2_M and
IN2_P pins to 5V by installing J7 and J8 on pins 1-2 puts the TPA3223 into 1x BTL mode (1 x mono output). This
is summarized in Table 3-4:

3.5 Audio Front End
The TPA3223EVM includes options for single-ended or differential input signals. A configurable front end is
built into the TPA3223 so that both single-ended and differential inputs can achieve the full scale output of the
TPA3223 device without need for external front end op-amp. Note that when EVM RCA or XLR connectors are
used, jumpers J11, J10, J21, and J20 must be installed in position 1:2 named XLR or RCA.
•
•
Single-ended input can be provided through RCA to inputs J3 and J18. Uninstall jumpers J4 and J12 using
SE input so that the TPA3223 front-end will be configured for SE input.
Differential input can be provided through XLR to inputs J14 and J15. Install jumpers J4 and J12 when using
DIFF input so that the TPA3223 front-end will be configured for DIFF input.
Input can also be provided through an audio plug-in board on J28. For this input type, change jumpers J11, J10,
J21, and J20 to position 2:3 named AIB.
See the EVM schematic section (Section 1.4.3) for complete details.

Hardware Configuration

3.6 EVM Power Tree
The TPA3223EVM includes a few options for power configuration so that various input types can be evaluated.
3.6.1 TPA3223 Supplies
The TPA3223 device has a few power supplies which each have their own voltage range and rules. Details for
each supply are as shown:
•
•
•
PVDD – This is the main device supply which accepts from 10 V to 45 V. Power output of the device is
derived solely from PVDD and therefore it is important to configure this supply according to the chosen output
configuration and load. Complete details are included in the TPA3223 datasheet.
VDD – This supply is used for the non-PVDD power of the device for blocks such as the front-end and control
circuitry. VDD is powered by 5 V directly and tied to GVDD and AVDD pins.
GVDD and AVDD – These pins are used for the gate drive and analog supply of the device. GVDD and
AVDD accept only 5 V which can be provided through the TP or the 5V through J24.

VDD (V)
10.0 to 45.0
AVDD (V)
5.0
5.0 (Tied to VDD)
GVDD (V)

3.6.2 TPA3223EVM Power Options
TPA3223 requires that 5 V is provided externally to VDD, AVDD, and GVDD. The major input configurations are
listed in the following sections by the supplies available.
3.6.2.1 PVDD Only (12 V to 45 V)
This power mode is the default setup when the board is tested and shipped. The user can connect any valid
supply voltage to J1 and the onboard LDOs will generate the required non-PVDD voltages. PVDD itself always
connects directly to the TPA3223 PVDD pins. Setup for this mode is the same as described in Quick Start (BTL
MODE).
3.6.2.2 PVDD (12 V to 45 V) and One Non-5-V Supply
This power mode is useful for certain applications where a system has one higher voltage used for PVDD and
a second lower voltage that may be used for device pullups and other supplies (VDD, GVDD, and AVDD). The
PVDD voltage can still be connected to J1 but jumpers J29 and J26 must be removed.
In the case of the TPA3223EVM, only 12V can be accepted as a non-5-V Supply and should be connected to pin
2 of J26 (12V).
3.6.2.3 PVDD (12 V to 45 V) and 5-V Supply
This power mode is most useful for systems in which a 5-V supply is already available due to additional circuitry
like an MCU or wireless module. On the EVM, this method is also the preferred way to measure efficiency of
the TPA3223 device. The PVDD voltage can still be connected to J1 but jumper J29 must be removed. The 5-V
supply must be connected to TP40.
The same 5-V input is used for the TPA3223 supplies (AVDD, VDD, and GVDD), the EVM reset control (U7), all
TPA3223 device pullups (RESET, HEAD, FREQ_ADJ, FAULT, OTW_CLIP), and status LEDs D4 and D2.
The 5-V supply can be isolated by by disconnecting J24. Once J24 jumper is removed, 5 V can be fed to only
the TPA3223 supplies through Pin 2 on the jumper and all other 5 V are being powered through 5 V LDO.
Either approach can be used to measure efficiency, but the most accurate numbers will be with the 5-V supply
separated so the TPA3223 supply voltage is isolated and measured independently of board LEDs, reset control,
and so forth.
3.7 LC Response and Overview
Included near the output of the TPA3223 device are four output LC filters. These output filters filter the PWM
output leaving only the audio content at high power which is fed to the speakers. The board uses a Sagami
10-µH inductor and 1-µF film capacitor to form this LC filter. Using the equations listed in LC Filter Design
(SLAA701), the filter low pass cut-off is as follows:

designing a different board featuring one of TI’s class-D amplifiers.
The Sagami inductor used (7G14D-100M-R) has a saturation current of 15 A. This was selected for the EVM
since the TPA3223 supports a maximum short-circuit output current of 9 A. The inductance versus current curve
for a selected inductor is very important. It is essential for the inductor to maintain at least 5 µH of inductance
at the maximum short-circuit current of the power amplifier. The Sagami inductance versus current curve is
available in the 7G14D-100M-R data sheet on the Sagami web site.
Although not required, shielded inductors are used on the EVM to reduce EMI.
3.8 Reset Circuit and POR
The TPA3223EVM includes RESET supervision so that the TPA3223 device remains in reset until all power rails
are up and stable. The RESET supervisor also maintains that the device is put into reset if one of the power rails
experiences a brown out. This circuit combined with the RESET switch (S1) helps make sure that the TPA3223
can be placed in reset easily, as needed, or automatically if there is a power supply issue. Figure 3-2 illustrates
the circuit.

3.9 Analog-Input-Board Connector (J28)
The Analog-Input-Board (AIB) connector allows for cross compatibility with several Analog Plug-in Modules
(APMs) offered by TI. This generic connector provides access to common board connections such as analog
input, analog output, Fault and overtemperature warning (OTW) error reporting, common board voltages (12 V,
3.3 V, and so forth), and EVM reset. These plug-in modules allow for an application-specific front end to be
plugged into the TPA3223EVM with ease. Examples of plug-in modules include front ends for guitar amplifier,
karaoke, wireless sub-woofer, and front-end audio crossover.
Figure 3-3. AIB EVM Connector
As Figure 3-3 shows, the AIB connector includes the following pins, associated specifications are listed in Table
3-7.

EVM Use Restrictions and Warnings:
4.1 EVMS ARE NOT FOR USE IN FUNCTIONAL SAFETY AND/OR SAFETY CRITICAL EVALUATIONS, INCLUDING BUT NOT
LIMITED TO EVALUATIONS OF LIFE SUPPORT APPLICATIONS.
4.2 User must read and apply the user guide and other available documentation provided by TI regarding the EVM prior to handling
or using the EVM, including without limitation any warning or restriction notices. The notices contain important safety information
related to, for example, temperatures and voltages.
4.3 Safety-Related Warnings and Restrictions:
4.3.1
User shall operate the EVM within TI’s recommended specifications and environmental considerations stated in the user
guide, other available documentation provided by TI, and any other applicable requirements and employ reasonable and
customary safeguards. Exceeding the specified performance ratings and specifications (including but not limited to input
and output voltage, current, power, and environmental ranges) for the EVM may cause personal injury or death, or
property damage. If there are questions concerning performance ratings and specifications, User should contact a TI
field representative prior to connecting interface electronics including input power and intended loads. Any loads applied
outside of the specified output range may also result in unintended and/or inaccurate operation and/or possible
permanent damage to the EVM and/or interface electronics. Please consult the EVM user guide prior to connecting any
load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative.
During normal operation, even with the inputs and outputs kept within the specified allowable ranges, some circuit
components may have elevated case temperatures. These components include but are not limited to linear regulators,
switching transistors, pass transistors, current sense resistors, and heat sinks, which can be identified using the
information in the associated documentation. When working with the EVM, please be aware that the EVM may become
very warm.
