Description and Introduction

Multi-Purpose Precision Multi-Phase PWM Controller With Optional Active Voltage Positioning The **ISL6558CRZ-T** is a **PWM controller** manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Intersil (Renesas Electronics)  
- **Package:** 28-Lead QSOP (QSOP-28)  
- **Operating Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable (supports multiple phases)  
- **Switching Frequency:** Programmable (typically up to 1MHz)  
- **Number of Phases:** Supports multi-phase operation (up to 4 phases)  
- **Control Method:** Voltage-mode PWM control  
- **Protection Features:** Overvoltage protection (OVP), undervoltage lockout (UVLO), overcurrent protection (OCP)  

### **Descriptions:**  
- The **ISL6558CRZ-T** is a high-performance **PWM controller** designed for **voltage regulator modules (VRMs)** and **DC-DC converters**.  
- It is optimized for **multi-phase synchronous buck converters**, commonly used in **CPU power supplies** and **high-current applications**.  
- The controller provides **precision voltage regulation** and **dynamic response** for demanding power supply designs.  

### **Features:**  
- **Multi-phase operation** (supports 2, 3, or 4 phases)  
- **Adaptive voltage positioning (AVP)** for improved transient response  
- **Programmable switching frequency** (up to 1MHz)  
- **Integrated MOSFET drivers** (requires external FETs)  
- **Differential remote voltage sensing** for accurate regulation  
- **Overcurrent protection** with programmable thresholds  
- **Overvoltage and undervoltage protection**  
- **Soft-start and soft-stop** functionality  

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