Power Requirements

The TPA102 MSOP audio power amplifier evaluation module can operate
from a V

DD

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 V

DD

supply from a

wide variety of unregulated V

CC

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 V

DD

voltage to the platform and the TPA102

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.

-

V

DD

voltage applied to platform screw terminals J6 must not exceed the

absolute maximum rating for the TPA102 amplifier IC installed on the eval-
uation module (5.5 V), or damage to the IC may result. In no case should
V

DD

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
V

DD

line will trip.

-

V

CC

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 V

CC

voltage applied to the platform exceed 15 V, or the

overvoltage protection circuit on the V

CC

bus will trip.
