5 V to 26 V • Efficient Class-D Operation – >90% Power Efficiency Combined With Low Idle Loss Greatly Reduces Heat Sink Size – Advanced Modulation Schemes • Multiple Switching Frequencies – AM Avoidance – Master and Slave Synchronization – Up to 1.
2-MHz Switching Frequency • Feedback Power-Stage Architecture With High PSRR Reduces PSU Requirements • Programmable Power Limit • Differential and Single-Ended Inputs • Stereo and Mono Mode With Single-Filter Mono Configuration • Single Power Supply Reduces Component Count • Integrated Self-Protection Circuits Including Overvoltage, Undervoltage, Overtemperature, DCDetect, and Short Circuit With Error Reporting • Thermally Enhanced Packages – DAD (32-Pin HTSSOP Pad Up) – DAP (32-Pin HTSSOP Pad Down) • –40°C to 85°C Ambient Temperature Range 2 Applications • Mini-Micro Component, Speaker Bar, Docks • After-Market Automotive • CRT TV • Consumer Audio Applications 3 Description The TPA31xxD2 series are stereo efficient, digital amplifier power stage for driving speakers up to 100 W / 2 Ω in mono.
The high efficiency of the TPA3130D2 allows it to do 2 × 15 W without external heat sink on a single layer PCB.
The TPA3118D2 can even run 2 × 30 W / 8 Ω without heat sink on a dual layer PCB.
If even higher power is needed the TPA3116D2 does 2 × 50 W / 4 Ω with a small heatsink attached to its top side PowerPAD.
All three devices share the same footprint enabling a single PCB to be used across different power levels.
The TPA31xxD2 advanced oscillator/PLL...
