  • Class D Audio Power Amplifier with built in Boost Converter

    Created by TINADesigner, published on 06-09-2012

    the TPA2015D1 is an high efficiency class D power amplifier. It has a built in boost converter to enhances efficiency at low power. An automatic gain control adjusts the class D gain to limit battery current and prevent clipping. An integrated low pass filter improves RF rejection and increases the signal to noise ratio SNR.The simulation is performed with a speaker modeled as an 8 ohm resistive load with its reactive components.
