Using The TPA112 MSOP EVM With the Plug-N-Play Evaluation Platform

3.3.3Power Requirements

The TPA112 MSOP audio power amplifier evaluation module can operate from a VDD voltage between approximately 2.5 V and 5.5 V.

The TI plug-n-play audio amplifier evaluation platform with a voltage regulator EVM installed on it can provide a regulated 3.3-V or 5-V 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 TPA112 evaluation module installed on it.

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 TPA112 amplifier IC installed on the evaluation module (5.5 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 will trip.

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 will trip.
