TPA3128D2DAPR New & Original DC To DC Converter & Switching Regulator Chip

short description:

The TPA3128D2 Class D amplifier has low idle power loss. This feature helps extend battery life in Bluetooth/wireless speakers and other battery-operated audio systems. The TPA3128D2 device is very efficient and can deliver 2 × 30W without the need for an external heat sink on a two-layer PCB. The TPA3128D2 advanced oscillator/programmable phase-locked loop (PLL) circuit features multiple switching frequency options. This option allows the device to avoid AM interference and, when used with the master/slave mode option, allows multiple devices to be synchronized.

Audio Power Amplifier Circuit

The audio power amplifier is used to amplify the power of the audio signal. The so-called power amplification is to realize the power amplification of the signal by first amplifying the signal voltage and then amplifying the signal current.
Knowing how audio power amplifiers work makes it easier to learn about other power amplifiers. Customarily, audio power amplifiers are also called low-amplification circuits (low-frequency signal amplifiers).
The audio power amplifier amplifies the audio signal. In different machines, different types of audio power amplifiers are used due to different requirements for output signal power.
