This reference design demonstrates a 450-W, 2-phase interleaved boost converter reference design for the Class-H audio amplifier application. To provide supply to the external audio amplifier, the controller is able to follow the Class-H control signal from the amplifier and generate an output voltage which tracks the speaker amplitude. Therefore, minimized overall power consumption and losses can be achieved.
