The IRAUDAMP19 reference design is a two-channel, 100W/ch (4 Ω/52V Bus voltage) half-bridge Class D audio power amplifier with single power supply. This reference design demonstrates how to use the IR4301 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).The reference design provides all the required housekeeping power supplies for ease of use. The two channel design is scalable for power and the number of channels.
Output Power: 100W x 2 channels (10%THD+N 4Ω load; no heatsink)
Multiple Protection Features: Over-current protection (OCP), high side and low side Over-voltage protection (OVP), Under-voltage protection (UVP), high side and low side Over-temperature protection (OTP)
