Description and Introduction

The IR3522 Control IC combined with IR3506 xPHASE3 Phase ICs implements a full featured DDR3 power solution. The IR3522M is a digital dual output voltage regulator from Infineon Technologies. Below are the factual details about its manufacturer, specifications, descriptions, and features:

### **Manufacturer:**  
Infineon Technologies  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 14V  
- **Output Voltage Range:** Programmable (0.3V to 5.5V)  
- **Output Current:** Up to 25A per phase (configurable)  
- **Switching Frequency:** 300kHz to 1.5MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 40-pin QFN (6mm x 6mm)  

### **Descriptions:**  
The IR3522M is a high-performance, dual-output PWM controller designed for voltage regulation in advanced computing and server applications. It integrates digital control with adaptive voltage positioning (AVP) and supports multi-phase operation for high-current applications.  

### **Features:**  
- **Digital Control Interface:** Supports PMBus for flexible configuration  
- **Adaptive Voltage Positioning (AVP):** Improves transient response  
- **Multi-Phase Operation:** Scalable for high-current designs  
- **Programmable Loop Compensation:** Optimizes stability  
- **Overcurrent, Overtemperature, and Undervoltage Protection:** Ensures system reliability  
- **Dynamic Phase Management:** Enhances efficiency at light loads  
- **Auto-Phase Shedding:** Reduces power loss
