IR IRS2092 1700W单路D类音频功率放大方案

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
