Using the TPA102 MSOP EVM With the Plug-N-Play Evaluation Platform
3-9
Details
3.3.4 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.
