Introduction
This section provides an overview of the Texas Instruments (TI) TPA2013D1 audio amplifier evaluation
module (TPA2013D1EVM). It includes a brief description of the module and a list of EVM specifications.
1.1
Description
The TPA2013D1 is a 2.7-W Class-D amplifier with built-in boost converter. It drives up to 2.7 W (10% THD
+ N) into a 4-Ω speaker from low supply voltages.
The TPA2013D1 audio power amplifier evaluation module is a complete, stand-alone audio board. It
contains the TPA2013D1 QFN (RGP) Class-D audio power amplifier with an integrated boost converter.
All components and the evaluation module are Pb-Free.

(TPA2013D1EVM). It includes a brief description of the module and a list of EVM specifications. Description The TPA2013D1 is a 2.7-W Class-D amplifier with built-in boost converter. It drives up to 2.7 W (10% THD + N) into a 4-Ω speaker from low supply voltages. - Page 2 2.1.3 Gain Control The TPA2013D1 has three gain settings: 2 V/V, 6 V/V, and 10 V/V. 1. Use jumper J13 to set the gain as 2 V/V, 6 V/V or 10 V/V. To achieve 2 V/V, place the jumper between heads 1 and 2;...
- Page 3 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 TPA2013D1 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.
- Page 4 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 TPA2013D1 are 4.7 μH to 6.8 μH.
