Description and Introduction

Multi-Purpose Precision Multi-Phase PWM Controller With Optional Active Voltage Positioning The ISL6558IR is a manufacturer part from INTERSIL (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** INTERSIL (now Renesas Electronics)  
- **Part Number:** ISL6558IR  
- **Type:** PWM Controller  
- **Package:** 28-Lead QFN (Quad Flat No-Lead)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable  
- **Switching Frequency:** Adjustable (typically up to 1MHz)  
- **Number of Phases:** Supports multi-phase configurations (up to 4 phases)  

### **Descriptions:**
The ISL6558IR is a high-performance PWM controller designed for voltage regulator modules (VRMs) and DC-DC converters. It provides precise voltage regulation for microprocessor and other high-current applications.  

### **Features:**
- **Multi-Phase PWM Control:** Supports 2, 3, or 4-phase operation for high-current applications.  
- **Adaptive Voltage Positioning (AVP):** Enhances transient response and reduces output capacitance.  
- **Programmable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Overcurrent Protection (OCP):** Monitors and protects against excessive current conditions.  
- **Overvoltage Protection (OVP):** Safeguards the load from voltage spikes.  
- **Differential Remote Voltage Sensing:** Ensures accurate regulation at the load.  
- **Power-Good Output:** Provides a signal indicating stable output voltage.  
- **Soft-Start Function:** Prevents inrush current during startup.  

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