XH-M577 TPA3116D2 High Power 12-24V Dual-Channel 2 X 80W Audio Amplifier Board

XH-M577 TPA3116D2 High Power 12-24V Dual-Channel 2 X 80W Audio Amplifier Board is an ultra-efficient Class D stereo amplifier module engineered around the popular Texas Instruments TPA3116D2 chip. This module offers impressive high-fidelity audio output, delivering up to 80 watts per channel (2x80W) into low-impedance speakers. The board features an integrated DC-DC boost converter, allowing it to generate the necessary high voltage for maximum output from a common 12V to 24V power supply. Consequently, this design flexibility simplifies power requirements while still maintaining the superior efficiency inherent to Class D amplification, which minimizes heat generation. Furthermore, its small form factor and robust protection features make it an ideal choice for DIY audio projects, home stereo upgrades, or portable sound systems requiring serious power.

Key Features:

• High Output Power: Utilizes the TPA3116D2 to deliver up to 2 x 80W output power into 4 Ω speakers, suitable for driving large bookshelf or tower speakers.
• Integrated Boost Converter: An on-board DC-DC boost circuit raises the input voltage internally, allowing the amplifier to achieve higher power output from lower external supply voltages.
• Class D Efficiency: The amplifier operates with very high efficiency (≥ 90%), therefore requiring only a passive heatsink for most applications and reducing power loss.
• Wide Supply Voltage Range: Accepts a 12V to 24V DC input, providing flexibility when sourcing power from common adapters or battery packs.
• Robust Protection: Includes comprehensive protection circuitry such as Overvoltage (OVP), Undervoltage (UVP), Overcurrent (OCP), and Thermal (OTP) shutdown.
