Description and Introduction

Protected Digital Audio Driver with Floating PWM input in a 16-Lead SOIC Narrow Package The IRS20955SPBF is a Class D audio amplifier IC manufactured by International Rectifier (IR). Below are the key specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** International Rectifier (IR)  
- **Type:** Class D Audio Amplifier IC  
- **Output Power:** Supports high-power output (exact power depends on external components)  
- **Supply Voltage Range:** Typically operates from ±40V to ±200V (floating gate drive)  
- **Switching Frequency:** Adjustable (typically up to 800kHz)  
- **Protection Features:** Overcurrent, undervoltage lockout (UVLO), and overtemperature protection  
- **Package:** 16-Lead SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
- The IRS20955SPBF is a high-performance, self-oscillating Class D audio amplifier driver with integrated protection features.  
- It is designed for high-efficiency audio amplification in applications such as home theater systems, professional audio, and automotive sound systems.  
- The IC includes a built-in PWM generator, gate drivers, and protection circuitry to simplify design and improve reliability.  

### **Features:**  
- **Self-Oscillating Topology:** Eliminates the need for an external oscillator.  
- **Floating Gate Drive:** Supports high-side and low-side MOSFETs for bridge-tied load (BTL) configurations.  
- **Adjustable Dead Time:** Helps optimize efficiency and reduce distortion.  
- **Integrated Fault Protection:** Includes overcurrent, undervoltage, and thermal shutdown.  
- **Low External Component Count:** Simplifies design and reduces PCB space.  

For exact performance characteristics, refer to the official datasheet from the manufacturer.
