IRAUDAMP12: 130W x 2, ±15 ~ 31V in, Class D

Summary

The IRAUDAMP12 reference design is a two-channel, 130 W/ch (4 Ω/±31 V; no heatsink)/ 160 W/ch (4 Ω/±34 V; *with heatsink) half-bridge Class D audio power amplifier.

This reference design demonstrates how to use the IR4301 IC, implement protection circuits, and design an optimum PCB layout using PowIRaudio integrated Class D IC.

This reference design does not require 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.
