Description and Introduction

A full featured and flexible way to implement a complete VR11.0 and VR11.1 power solution. The IR3503M is a digital PWM controller manufactured by International Rectifier (IR). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:**  
International Rectifier (IR)  

### **Part Number:**  
IR3503M  

### **Description:**  
The IR3503M is a digital PWM controller designed for high-performance voltage regulator modules (VRMs) and power supplies. It provides precise voltage regulation and supports multi-phase operation for efficient power delivery.  

### **Key Features:**  
- **Digital Control:** Uses a digital control loop for accurate voltage regulation.  
- **Multi-Phase Operation:** Supports multi-phase configurations for scalable power delivery.  
- **Adaptive Voltage Positioning (AVP):** Enhances transient response and efficiency.  
- **Programmable Parameters:** Allows customization of switching frequency, phase count, and protection settings.  
- **Fault Protection:** Includes over-voltage (OVP), under-voltage (UVP), over-current (OCP), and thermal shutdown.  
- **High Efficiency:** Optimized for synchronous buck converters.  
- **Communication Interface:** Supports PMBus or I²C for system monitoring and configuration.  
- **Wide Input Voltage Range:** Compatible with various input voltage levels.  

### **Applications:**  
- Voltage regulator modules (VRMs)  
- High-performance computing power supplies  
- Server and data center power systems  
- Industrial power supplies  

This information is based solely on the manufacturer's specifications and datasheet. For detailed electrical characteristics and application notes, refer to the official IR3503M datasheet.
