Description and Introduction

Multi-Phase PWM Controller with Precision Rds(on) or DCR Differential Current Sensing for VR10.X Application The ISL6561IRZ-T 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:

### **Specifications:**  
- **Input Voltage Range:** 5V to 12V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** Adjustable up to 1MHz  
- **Maximum Duty Cycle:** 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead QFN (5x5mm)  

### **Descriptions:**  
- Designed for single-phase voltage regulator applications.  
- Supports synchronous buck converter topologies.  
- Features adaptive voltage positioning (AVP) for improved transient response.  
- Includes integrated MOSFET drivers.  

### **Features:**  
- **Precision Voltage Regulation:** ±1% accuracy over temperature.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Overcurrent Protection (OCP):** Monitors output current.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage.  
- **Power-Good Output:** Indicates stable output voltage.  

This information is strictly based on the manufacturer's datasheet. For detailed application notes or design guidelines, refer to the official documentation.
