Description and Introduction

A full featured and flexible way to implement power solutions for the latest high performance CPUs and ASICs. **Manufacturer:** Infineon Technologies (formerly International Rectifier)  
**Part Number:** IR3086AMTRPBF  

### **Specifications:**  
- **Category:** Power Management IC (PMIC)  
- **Function:** Multi-Phase PWM Controller  
- **Output Phases:** Configurable for 3, 4, 5, or 6 phases  
- **Input Voltage Range:** 4.5V to 15V  
- **Output Voltage Range:** Programmable (0.6V to 1.85V)  
- **Switching Frequency:** Adjustable (200kHz to 1MHz)  
- **Control Method:** Predictive Current Control (PCC)  
- **Package:** 48-Pin QFN (7mm x 7mm)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The IR3086AMTRPBF is a high-performance, multi-phase PWM controller designed for voltage regulator modules (VRMs) and point-of-load (POL) applications. It supports adaptive voltage positioning (AVP) and provides precise voltage regulation for high-current CPUs, GPUs, and ASICs.  

### **Features:**  
- **Multi-Phase Operation:** Supports 3 to 6 phases for scalable power delivery.  
- **Predictive Current Control (PCC):** Enhances transient response and efficiency.  
- **Adaptive Voltage Positioning (AVP):** Reduces output capacitance requirements.  
- **Programmable Frequency:** Adjustable from 200kHz to 1MHz.  
- **Overcurrent Protection:** Integrated fault protection.  
- **Thermal Monitoring:** Supports external temperature sensing.  
- **Digital Soft-Start/Stop:** Ensures controlled power-up sequencing.  
- **Lead-Free & RoHS Compliant:** Meets environmental standards.  

This information is based on Infineon's datasheet for the IR3086AMTRPBF.

Application Scenarios & Design Considerations
