IR公司的 IRS2092是集成了PWM调制器和保护的高压高性能D类音频放大器,工作频率高达800kHz,±100 V额定电压是可提供500W输出功率,主要用在家庭影院,密你立体声系统,通用音频放大器等。本文介绍IRS2092主要特性,方框图,典型连接图,典型应用电路图以及1700W单路D类音频功率放大器框图,主要特性,电路图和材料清单。
The IRS2092 is a high voltage, high performance Class D audio amplifier driver with PWM modulator and protection.
In conjunction with two external MOSFET and a few external components, a complete Class D audio amplifier with protection can be realized.
International Rectifier’s proprietary noise isolation technology allows high current gate drive stage and high speed low noise error amplifier reside on a single small silicon die.Open elements of PWM modulator section allow flexible PWM topology implementation.

IRS2092主要特性:
• Integrated analog input Class D audio amplifier driver in a small 16 pin package
• Floating inputs enable easy half bridge implementation
• Programmable bidirectional over-current protection with self-reset function
• Programmable preset deadtime for improved THD performances
• Start and stop click noise reduction
• High noise immunity
• ±100 V ratings deliver up to 500 W in output power
• Operates up to 800 kHz
• RoHS compliant

IRS2092典型应用:
• Home theater systems
• Mini component stereo systems
• Powered speaker systems
• General purpose audio power amplifiers

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 <2° C / W).

1700W单路D类音频功率放大器主要应用:
• Pro-Audio amplifiers
• Powered speakers
• Active Sub-woofers
• P.A. Systems
• Car audio amplifiers
Musical Instrument amplifier
