An amplifier system includes an audio amplifier and a power converter. The audio amplifier is powered by at least a first supply voltage and a second supply voltage, the audio amplifier configured to receive an audio signal to generate an output signal. The power converter includes only one inductor and is configured to generate a first power supply voltage and a second power supply voltage according to an input voltage. The overall dimension and the manufacturing cost of the power converter can be reduced. 本发明提供了一种放大器系统，包括音频放大器和电源转换器。音频放大器至少由第一电源电压和第二电源电压供电，音频放大器被配置为接收音频信号以产生输出信号。电源转换器包含仅一个电感器，且被配置为根据输入电压产生第一电源电压与第二电源电压。本发明能够减少电源转换器的外形尺寸和制造成本。
