IRS2092PBF

Product Summary

The IRS2092PBF 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, the IRS2092PBF 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. The applications of the IRS2092PBF include Home theater systems, Mini component stereo systems, Powered speaker systems, General purpose audio power amplifiers.
