Texas Instruments LM25122-Q1 | Demoboard PMP11769
700W Automotive External Audio Amplifier Reference Design
Details
| Topologie | Aufwärtswandler |
| Eingangsspannung | 6-16 V |
| Ausgang 1 | 36 V / 10 A |
| IC-Revision | C |
Beschreibung
The PMP11769 reference design is a complete solution for a 700W automotive external amp. The boost converter provides 36.0V @ 10.0A continuous / 20.0A peak from an input voltage of 9-16V. It contains two premium Class-D audio amplifiers, which provide 2x 175W @ 4-Ω load (left & right channel) and 1x 350W @ 2-Ω (subwoofer).The design is well suited for car audio external amp applications due to its thin profile and high power output.
Eigenschaften
- Easily integrated into automotive systems with 50V load dump and integrated protection system
- Ultra-HD audio for best quality sound for any integrated Class-D amplifier
- 100kHz bandwidth, which enables support for high resolution audio files and formats
- Low noise, which eliminates the "hiss" or "buzz" sounds
Typische Anwendungen
- Aftermarket audio amplifier / Automotive external amplifier / Virtual engine sound system (VESS) / Welding machine
