AB  - Switching Power amplifiers are becoming quite common in audio applications, thanks to semiconductor technology advances, because of their intrinsic optimal efficiency. However usually they are used for low/medium quality application and low frequency loudspeaker systems. In this paper the design of a large bandwidth switching audio amplifier is presented. The amplifier is specifically aimed at automotive applications, where supply voltage, power consumption, and size are peculiar constraints. A prototype featuring reduced distortion, suitable for large bandwidth loudspeakers was realized and successfully tested.
