Power Requirements

-When JP6 is set to mode, use the following JP8 settings for the TPA6011A4:

J To switch the TPA6011A4 amplifier module to the single-ended output mode when a plug is inserted into the headphone jack, jumper JP8 to Hi (this is the typical setting).

J To switch the TPA6011A4 amplifier module to the BTL output mode when a plug is inserted into the headphone jack, jumper JP8 to Lo.

3.3.5Power Requirements

The TPA6011A4 audio power amplifier evaluation module can operate from any voltage between approximately 4.5 V and 5.5 V; however, the TPA6011A4 amplifier IC on the module is characterized for operation at 5 V. For best performance (highest output power with lowest distortion), the module should be operated at approximately 5 V unless there is a specific reason for operating it from a different voltage.

The TI plug-n-play audio amplifier evaluation platform with a voltage regulator EVM installed on it can provide a regulated VDD supply from a wide variety of unregulated VCC voltage inputs between approximately 5.5 V and 12 V, including an onboard 9 -V battery. Or, an external regulated power source can be used to supply VDD voltage to the platform and the TPA6011A4 evaluation module installed on it.

Although the TPA6011A4 amplifier IC draws approximately 0.65 A from the power supply during continuous full power output, peak current draw can be as high as 1 A. Any power supply connected to the platform should be capable of providing 1 A of current to avoid clipping of the output signal during peaks. Current consumption driving speakers at normal listening levels is typically 0.3 A or less.

The platform is equipped with overvoltage and reverse-polarity supply voltage input protection in the form of fused crowbar circuits.

-VDD voltage applied to platform screw terminals J6 MUST NOT exceed the absolute maximum rating for the TPA6011A4 amplifier IC installed on

the evaluation module (6 V) or damage to the IC may result. In no case

should VDD voltage of the incorrect polarity or in excess of 6.1 V be applied to screw terminals J6 of the platform, or the power protection circuit on the VDD line is tripped.

-VCC voltage applied to the platform MUST NOT exceed the maximum voltage input specified for the voltage regulator module installed in socket

U6 (12 V for the SLVP097), or damage to the voltage regulator module

may result. In no case should VCC voltage applied to the platform exceed 15 V, or the overvoltage protection circuit on the VCC bus is tripped.
