Description and Introduction

Multi-Phase PWM Controller with Precision Rds(on) or DCR Differential Current Sensing for VR10.X Application The ISL6561IRZ 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 via external components  
- **Switching Frequency:** Adjustable (typically up to 1MHz)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC (IRZ denotes the RoHS-compliant package)  
- **Control Method:** Voltage-mode PWM control  

### **Descriptions:**
- Designed for single-phase DC-DC voltage regulator applications.  
- Optimized for driving N-channel MOSFETs in synchronous buck topologies.  
- Supports high-efficiency power conversion for CPUs, GPUs, and other low-voltage applications.  

### **Features:**
- **Integrated MOSFET Drivers:** Includes high-current gate drivers for N-channel MOSFETs.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent Protection:** Uses MOSFET RDS(ON) sensing for accurate current limiting.  
- **Overvoltage Protection (OVP):** Safeguards the load from excessive voltage.  
- **Power-Good Output:** Provides a signal indicating stable output voltage.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Thermal Shutdown:** Protects the IC from overheating.  

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