Description and Introduction

PWM Controller, 2-4 Phase, 5-Bit VID, ?% Reg, VCORE =0.80/1.55V The ISL6559 is a high-performance PWM controller manufactured by Intersil (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features of the ISL6559:  

### **Manufacturer:**  
- **Intersil (now Renesas Electronics)**  

### **Specifications:**  
- **Output Configurations:** Multi-phase (2, 3, 4, or 5 phases)  
- **Input Voltage Range:** 5V to 12V (VCC)  
- **Switching Frequency:** Adjustable (100kHz to 1MHz)  
- **Duty Cycle Range:** 0% to 100%  
- **Control Method:** Voltage-mode PWM  
- **Protection Features:** Overvoltage (OVP), undervoltage (UVP), and overcurrent (OCP) protection  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 40-lead QFN (6mm x 6mm)  

### **Descriptions:**  
- The ISL6559 is a multi-phase PWM controller designed for high-current DC-DC converters, commonly used in VRM (Voltage Regulator Module) applications.  
- It provides precise voltage regulation for microprocessors and other high-performance digital ICs.  
- The controller supports adaptive phase shedding to improve efficiency at light loads.  

### **Features:**  
- **Multi-Phase Operation:** Supports 2 to 5 phases for high-current applications.  
- **Precision Voltage Regulation:** ±0.5% system accuracy over temperature.  
- **Dynamic Phase Control:** Automatically adjusts the number of active phases for optimal efficiency.  
- **Programmable Switching Frequency:** Adjustable from 100kHz to 1MHz.  
- **Integrated MOSFET Drivers:** Supports high-side and low-side drivers.  
- **Fault Protection:** Includes OVP, UVP, and OCP for system reliability.  
- **Differential Remote Sensing:** Compensates for PCB trace resistance.  
- **Soft-Start and Soft-Stop:** Reduces inrush current during startup.  

This information is based on the manufacturer's datasheet and technical documentation.
