... Introduction The IRAUDAMP15 reference design is a two-channel, 35W/ch half-bridge Class D audio power amplifier with single power supply. This reference design demonstrates how to use the IR4311 IC with single power supply, implement protection circuits, and design an optimum PCB layout using PowIRaudio integrated Class D IC. This reference design does not require additional heatsink or fan cooling for normal operation (one-eighth of continuous rated power) ...
