IRAUDAMP9:1.7 kW / 2-Ω Single Channel Class D Audio Power Amplifier Using the IRS2092S and IRFB4227
The IRAUDAMP9 reference design is a single-channel 1.7-kW ( @ 2Ω load) half-bridge Class D audio power amplifier. This reference design demonstrates how to use the IRS2092S Class D audio controller and external gate buffer, to implement protection circuits, and design an optimum PCB layout using the IRFB4227 (x 2 Pairs) TO-220 MOSFETs. This reference design may require additional heatsink or fan for normal operation (one-eighth of continuous rated power). The reference design provides all the required housekeeping power supplies for ease of use. The 1-channel design is capable of delivering higher than its rated power with provision of larger heat sink ( Rth <>? C / W).
