Key Parameters Key Parameters Power Supply Voltage 8 V to 26 V Number of Channels 1 - Bridge-Tied Load (BTL) Mono Load Impedance Mono BTL 4 Ω to 8 Ω (connect 33-mH series inductor for 4-Ω, 68-mH inductor or 8 Ω if using the ferrite bead filters) Output Power 10 W 2 Operation 2.1 Quick-Start List for Stand-Alone Operation Follow these steps to use the TPA3111D1EVM stand-alone or when connecting it into existing circuits or equipment. Connections to the EVM module can be made by inserting stripped wire or banana plugs for the power supply and output connections. The outputs also can be connected via Molex connectors. The input connectors are RCA phono jacks. SLOU270A – September 2009 – Revised July 2010 TPA3111D1EVM Audio Amplifier Evaluation Board Copyright © 2009–2010, Texas Instruments Incorporated 3 Operation www.ti.com Power Supply A single power supply is required to power up the EVM. Most of the pins are PVCC compliant. The PVCC supply can also be used to power the analog supply (AVCC) and can be used to pull up the logic pins for shutdown (SD) control, fault detection (FAULT), and gain (GAIN0 and GAIN1) as long as the voltage slew rate is limited to 10 V/ms. GVDD is an internally generated supply for the output FETs and also can be used to power the PLIMIT circuit. PLIMIT is GVDD compliant, but not PVCC compliant. PLIMIT also can be powered by an external supply connected to the PLIMIT pin. Take care not to power the PLIMIT pin (or connect power to the GVDD pin inadvertently through the PLIMIT network) when the PVCC supply is turned off. This can cause damage to the integrated circuit (IC). Table 2. Power Supply Requirements Description Voltage Range Current Requirements Minimum Wire Size PVCC 8 to 26 V 3A 24 AWG 1. Ensure that the external power source is set to OFF. 2. Connect the external regulated power supply adjusted from 8 V to 26 V to the module PVCC and GND banana jacks, taking care to observe marked polarity. Evaluation Module Preparations Inputs and Outputs 1. For a BTL configuration, connect a load across the outputs (OUT+ and OUT-). 2. Connect the audio input, either differential or single-ended, to the IN RCA phono plugs for BTL operation. Control Inputs 1. Ensure that the mode jumpers, JP1, JP2, GAIN0, and GAIN1, are set correctly depending on the desired operating state (Table 3). Power Up 1. Verify correct voltage and input polarity, and turn the external power supplies ON. The EVM begins operation. 2. Adjust the audio source for the desired volume. Table 3. TPA3111D1 Control Guide Control Function Options Notes JP1 Allows amplifier to self-reset after short-circuit protection event Insert jumper for self-reset. Leave off for latched SC fault. For latched SC fault, cycle power to reset the fault latch. DC Detect does not recover with SDZ cycle. PVCC must be cycled to reset DC Detect. GAIN1/GAIN0 Controls amplifier gain Insert jumper for zero state (low). Leave off for one state (high). 00 01 10 11 JP2 Defeats PLIMIT function and allows amplifier to run at full power. Insert jumper for PLIMIT defeat. JP2 connects PLIMIT directly to GVDD. R7 Adjust PLIMIT (an external voltage also can be applied to the PLIMIT test point) Remove JP2 to allow PLIMIT The output voltage rails are limited to operation. approximately 4X the voltage at the PLIMIT pin. Take care not to apply power to PLIMIT when the PVCC source is off. JP3, JP4 Connects LC filters to outputs. 4 TPA3111D1EVM Audio Amplifier Evaluation Board = 20 = 26 = 32 = 36 dB (GAIN1, GAIN0) dB dB dB SLOU270A – September 2009 – Revised July 2010 Copyright © 2009–2010, Texas Instruments Incorporated SLOU270A – September 2009 – Revised July 2010 2 1 2 1 Black Red JP5 2 GND 1.0ufd/16V 0603 C2 1.0ufd/16V 0603 GND 10,1/4W 1206 R5 GND 2 AVCC 1.0ufd/16V 0603 JP2 GND 1.0ufd/16V 0603 1 AGND Black C5 3303W R7 AVCC GND FAULT C4 10K 1.0ufd/35V 0603 GND PLIMIT 1.00K 0603 R6 GND C3 2 SD PVCC 25 Copyright © 2009–2010, Texas Instruments Incorporated 15 14 GND PowerPad U1 TPA3111D1PWP 13 17 18 19 20 21 22 23 24 16 12 11 10 9 8 7 6 GND GND GND 1000pfd/50V 0603 C17 Black GND Black GND GND 0.1ufd/50V 0603 C18 0.47ufd/16V 0603 C14 10 1/4W 0805 R12 10 1/4W 0805 R9 0.47ufd/16V 0603 C9 GND GND 4 26 0.1ufd/50V 0603 5 C7 1000pfd/50V 0603 27 28 C6 TSSOP28-PWP U1 3 2 1 FB1 C12 C13 GND 100ufd/35V VS-D8 C19 PVCC 2 1 5A/80ohms/100MHz 0805 FB2A 75 Ohms@100MHz,5A 28L0138 FB2 GND GND 75 Ohms@100MHz,5A 28L0138 1000pfd/50V 0603 + FB1A 2 1 5A/80ohms/100MHz 0805 GND 100ufd/35V VS-D8 C8 1000pfd/50V 0603 + PVCC GND 2 1 1 1 JP4 JP3 2 OUT 2 1 1 L1 22uH DS104C2 L2 22uH DS104C2 GND 0.875in GND 0.875in GND 0.875in 2 2 GND 0.875in STANDOFFS 1000pfd/50V 0603 C25 GND 1000pfd/50V 0603 C10 TP1 TP2 GND 0.68ufd/50V 1206 C16 GND 0.68ufd/50V 1206 C11 Red Red OUT+ OUT- TPA3111D1EVM Schematic 3 1 1 C1 PVCC JP1 1 R3 100K 0603 3.1 2 R2 100K 0603 R1 PVCC 100K 0603 PVCC S1 Schematic, Layout, and Bill of Materials RCA (Red) GND GND GND TPA3111D1PWP EVALUATION BOARD 3 IN GAIN1 GAIN0 GND PVCC PVCC www.ti.com Schematic, Layout, and Bill of Materials Figure 3.

FCC Warning This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15 of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this equipment in other environments may cause interference with radio communications, in which case the user at his own expense will be required to take whatever measures may be required to correct this interference. EVM Warnings and Restrictions It is important to operate this EVM within the input voltage range of -0.3 V to 6.3 V and the output voltage range of -0.3 V to 30 V . Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions concerning the input range, please contact a TI field representative prior to connecting the input power. Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM. Please consult the EVM User's 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, some circuit components may have case temperatures greater than 85° C. The EVM is designed to operate properly with certain components above 85° C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.
