Eight-channel 1kVA Class-H audio amplifier reference design
TIDA-020088
概述
This reference design demonstrates a 1kVA Class-H audio and tracking power supply audio subsystem. The TAS6684-Q1 audio amplifier tracks the envelope of the digital audio input and adjusts the LM5125A-Q1 boost output voltage to meet the power efficiency requirements without the need for an external microcontroller. This design leads to improved efficiency, thermal performance, and a smaller total footprint. In addition, this reference design allows for a Class-H implementation to be plug-and-play with minimal software changes to the rest of the automotive audio architecture.
特性
- TAS6684-Q1 is a 45V automotive Class-D audio amplifier with integrated current sense and integrated Class-H control
- Maximum output power and high-fidelity audio
- LM5125A-Q1 is a wide-VIN dual-phase synchronous boost controller with a ATRK/DTRK pin for simplified tracking power-supply design
- Self-contained Class-H control allows for simplified implementation in external amplifier applications and minimizes the need for additional digital power controller or software
- Includes an input protection circuit to protect against external transients, reverse battery conditions, and system overcurrent events
