<p>An audio power amplifier (200) including a rail voltage detection circuit (202, 204, 206, 208) connected to a feedback generator (212) and a rail voltage (106, 110), the detection circuit (202, 204, 206, 208) is adapted to detect an overvoltage or undervoltage condition and control (214) the feedback signal (FS) to a regulated switching power supply to adjust the rail voltage (106, 110). Additional protection is provided through thermal stress detection and output fault detection to control (214) the feedback signal (FS) and protect the audio power amplifier (200).</p> |
