IRS2092PBF

Overview

The IRS2092PBF is a high-voltage, high-performance Class D audio amplifier driver featuring an integrated PWM modulator and protection circuitry. It operates with a low-side supply voltage range of 10 V to 18 V and supports floating inputs up to ±200 V. The device delivers gate drive currents of 1.0 A (source) and 1.2 A (sink). Key electrical parameters include a maximum DC offset of 60 dB, THD+N of 0.01% at 1 kHz, and residual noise of 200 µVrms. It supports switching frequencies up to 800 kHz and offers selectable deadtime options of 25, 40, 65, or 105 ns.

Feature Summary

• 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
• Start and stop click noise reduction

Applications

• Home theater systems
• Mini component stereo systems
• Powered speaker systems
• General purpose audio power amplifiers

Procurement Notes

Verify the specific ordering suffix for the required package type before procurement. The 'P' suffix indicates a PDIP16 tube/bulk package containing 25 units per standard pack. Confirm that the selected variant aligns with the intended manufacturing process and assembly requirements. Ensure compatibility with the system's thermal management strategy given the junction temperature limits.

Selection Notes

Select this component when designing single-channel Class D amplifiers requiring integrated PWM modulation and protection. It is suitable for applications needing high noise immunity and flexible topology implementation through open elements in the PWM section. Consider the available package options based on board space constraints and thermal dissipation needs.

Part Context

The IRS2092PBF belongs to the IRS2092 family of protected digital audio amplifier drivers manufactured by Infineon Technologies (formerly International Rectifier). This series includes variants such as the SOIC16N and Tape & Reel versions. The device utilizes proprietary noise isolation technology to house high-current gate drive stages and low-noise error amplifiers on a single silicon die.

Replacement Considerations

Direct substitutes within the same product line include the IRS2092SPBF (SOIC16N package) and the IRS2092STRPBF (Tape and Reel version). These alternatives share identical electrical characteristics and pinouts but differ in packaging format and shipping quantity.
