Texas Instruments LM25122-Q1 | Demoboard PMP11769 | Würth Elektronik Reference Design Search

Overview

Topology	Buck-Boost Converter
Input voltage	35-37 V
Output 1	-12 V / 0.05 A
IC revision	C

Description

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.

Features

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

Typical applications

Aftermarket audio amplifier / Automotive external amplifier / Virtual engine sound system (VESS) / Welding machine
