3-channel, 200V driver IC from IR for class D audio applications

International Rectifier (IR) has unveiled the IRS2053M, 200V driver IC for use in Class D Audio applications including high performance home theater systems and car audio amplifiers requiring a compact footprint.

Based on a Class D audio amplifier topology, the IRS2053M integrates three channels of high-voltage, high performance half-bridge drivers with PWM modulators. The new device’s comprehensive set of protection features includes programmable bi-directional current sensing to protect high- and low-side MOSFETs from over-current conditions. Other key features include logic compatible input and floating PWM input.

“The IRS2053M offers a Class D Audio solution with excellent sound quality, delivering a smaller footprint and higher power compared to alternative solutions when combined with IR’s high efficiency power MOSFETs. Moreover when co-designed with the single channel IRS2092(S) and four channel IRS2093M, the IRS2053M offers the flexibility to configure 2.1channel, 6 channel and 6.1channel applications,” said Jun Honda, director of audio systems engineering, Energy Saving Products Business Unit.
