The TI Plug-N-Play Audio Amplifier Evaluation Platform with a voltage
regulator EVM installed on it can provide a regulated 5-V V
wide variety of unregulated V
and 12 V, including an on-board 9 -V battery. Or, an external regulated power
source can be used to supply V
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.
