Description and Introduction

Multi-Purpose Precision Multi-Phase PWM Controller With Optional Active Voltage Positioning The **ISL6558IRZ-T** is a **PWM (Pulse Width Modulation) controller** manufactured by **INTERSIL** (now part of **Renesas Electronics**). Below are its key specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Manufacturer:** INTERSIL (Renesas Electronics)  
- **Package:** 28-Lead QFN (Quad Flat No-Lead)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 4.5V to 12V  
- **Output Voltage Range:** Programmable (supports multi-phase buck converters)  
- **Switching Frequency:** Adjustable (typically up to 1MHz per phase)  
- **Number of Phases:** Supports 2 to 4 phases  
- **Duty Cycle Range:** 0% to 100%  
- **Control Method:** Voltage-mode PWM control  

### **Descriptions:**  
- The **ISL6558IRZ-T** is a **multi-phase PWM controller** designed for **high-performance voltage regulation** in **CPU power supplies** and **graphics card VRMs (Voltage Regulator Modules)**.  
- It provides **precise voltage regulation** with **adaptive voltage positioning (AVP)** to optimize transient response.  
- Supports **synchronous rectification** for improved efficiency.  
- Includes **overcurrent protection (OCP), overvoltage protection (OVP), and undervoltage lockout (UVLO)**.  

### **Features:**  
- **Multi-phase operation (2 to 4 phases)** for high-current applications.  
- **Adaptive Voltage Positioning (AVP)** for dynamic load response.  
- **Programmable switching frequency** for design flexibility.  
- **Differential remote voltage sensing** for accurate regulation.  
- **Integrated MOSFET drivers** (requires external MOSFETs).  
- **Power Good (PGOOD) indicator** for system monitoring.  
- **Adjustable soft-start** for controlled power-up sequencing.  
- **Lead-free and RoHS compliant**.  

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

Application Scenarios & Design Considerations

Multi-Purpose Precision Multi-Phase PWM Controller With Optional Active Voltage Positioning

Alternative Part Number

  • ISL6568CRZ --: Same Intersil/Renesas multiphase PWM controller family with comparable VRM control features; different series prefix makes it easy to distinguish from the source.
  • ADP3198JCPZ-RL --: Analog Devices multiphase buck controller offering similar PWM regulation functionality and a clearly different naming series.
  • NCP5386MNR2G --: ON Semiconductor multiphase PWM controller with comparable voltage regulator control role and a distinct part-number series.
  • HIP6311ACBZ --: Multi-phase PWM controller from the same vendor family with comparable buck regulation features; different series name makes it easy to distinguish from the source.
  • NCP5386BMNR2G --: Multi-phase synchronous buck controller offering similar VRM control functionality and a different naming scheme.
