Description and Introduction

Control IC combined with an XPHASE3 IC provides a full featured and flexible way to implement a complete VR11.0 and VR11.1 power solution. The IR3502BM is a digital PWM controller designed for high-performance voltage regulator applications. Below are the factual details about its manufacturer, specifications, descriptions, and features:

### **Manufacturer:**  
- **Infineon Technologies** (formerly International Rectifier or IR)  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 21V  
- **Output Voltage Range:** Programmable (0.6V to 5.5V)  
- **Switching Frequency:** Adjustable (200kHz to 1MHz)  
- **Number of Phases:** Single or Multi-Phase Configurable (up to 8 phases)  
- **Control Method:** Digital PWM (Pulse Width Modulation)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 48-pin QFN (Quad Flat No-Lead)  

### **Descriptions:**  
- The IR3502BM is a digital PWM controller optimized for high-efficiency voltage regulation in power supply designs.  
- It supports adaptive voltage positioning (AVP) and dynamic phase control for improved transient response.  
- The device integrates a high-resolution digital control loop for precise voltage regulation.  
- It is commonly used in server, telecom, and industrial power applications.  

### **Features:**  
- **Digital Control:** Enables precise voltage regulation and dynamic adjustments.  
- **Multi-Phase Operation:** Supports up to 8-phase configurations for high-current applications.  
- **Adaptive Voltage Positioning (AVP):** Reduces output capacitance requirements.  
- **Programmable Switching Frequency:** Adjustable from 200kHz to 1MHz.  
- **Overcurrent and Overtemperature Protection:** Enhances system reliability.  
- **PMBus™ Compliant:** Allows communication and monitoring via the PMBus interface.  
- **Dynamic Phase Control:** Optimizes efficiency under varying load conditions.  

These details are based on the official specifications from Infineon Technologies (formerly IR). For exact application-specific details, refer to the datasheet.
