» Class D Audio Amplifier Board, 12v Audio Amp Module
Product Description:
• Output Power: Maximum 15W at RL=6Ω, VCC=15V, BTL
Rating 10W at RL=4Ω, VCC=12V, BTL
• Power
efficiency is up to 82%
• Low Working Voltage Down To 5V, High Working Voltage up To 15V
• Thermal Protection function
• Output Pin Short-Circuit Protection
• Low Supply Current (5mA Typical at 12V)
• Low Current in Shutdown Mode (<1µA Typical)
• Separate VCC & PVCC
• Class-D audio design
• Components use SMT decal, the board dimension is very small
• IC decal is TSSOP20
• No external heat-sink, Less heat, save heat sink cost
• The current is very small
• The PCB design provides both bead and LC solutions
• The dimension is only 42mm×30mm
