摘要： A power converter receiving a single-sided supply which is ground-terminated and providing a regulated positive supply and a regulated negative supply that is optimized to the expected output range of a class AB amplifier, as well as providing excellent efficiency. The converter finds application as a compact converter to power an audio amplifier driving an audio device which is ground terminated, such as a speaker.

摘要翻译： 接收单端电源的功率转换器，其接地端接并提供调节的正电源以及针对AB类放大器的预期输出范围优化的调节负电源，以及提供优异的效率。 该转换器将应用程序用作紧凑型转换器来为驱动接地终止的音频设备（例如扬声器）的音频放大器供电。
