Description and Introduction

PWM Controller, 2-4 Phase, 6-Bit VID, Precision R DS (on) or DCR sensing, Reg ?.5% The ISL6561 is a single-phase 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:**
- **Input Voltage Range:** 5V to 12V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable up to 1MHz  
- **Maximum Duty Cycle:** Up to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 16-Lead QSOP  

### **Descriptions:**
- The ISL6561 is a **single-phase buck PWM controller** designed for **voltage regulator modules (VRMs)** and **DC-DC converters**.  
- It integrates **MOSFET drivers** and provides **precise voltage regulation** for high-performance processors and power supplies.  
- Supports **adaptive voltage positioning (AVP)** for improved transient response.  
- Includes **overcurrent protection (OCP)**, **overvoltage protection (OVP)**, and **undervoltage lockout (UVLO)**.  

### **Features:**
- **Precision Voltage Regulation:** ±1% accuracy over temperature.  
- **Adjustable Switching Frequency:** Up to 1MHz for optimized efficiency.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Differential Remote Sensing:** Ensures accurate output voltage control.  
- **Programmable Soft-Start:** Prevents inrush current issues.  
- **Power-Good Output:** Monitors output voltage status.  
- **Synchronous Rectification:** Improves efficiency.  

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