Description and Introduction

Multi-Phase PWM Controller with Precision Rds(on) or DCR Differential Current Sensing for VR10.X Application The ISL6561CRZA-T is a product from Intersil (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:** Intersil (Renesas Electronics)  
### **Part Number:** ISL6561CRZA-T  

### **Description:**  
The ISL6561CRZA-T is a single-phase PWM controller designed for voltage regulation in microprocessor core power supplies. It provides high-performance power regulation for applications such as desktops, workstations, and servers.  

### **Features:**  
- **Single-Phase PWM Controller** for voltage regulation.  
- **Precision Voltage Regulation** with ±1% system accuracy over temperature.  
- **Integrated MOSFET Drivers** for high-side and low-side MOSFETs.  
- **Adaptive Non-Overlap Gate Drive** to prevent shoot-through.  
- **Programmable Switching Frequency** (up to 1MHz).  
- **Differential Remote Voltage Sensing** for accurate output regulation.  
- **Overcurrent Protection** with adjustable threshold.  
- **Overvoltage Protection (OVP)** for enhanced system safety.  
- **Power-Good Output** for system monitoring.  
- **Thermal Shutdown** for protection against overheating.  
- **5V or 12V Input Supply Operation** for flexibility.  

### **Package:**  
- **24-Lead QFN (Quad Flat No-Lead) Package** (6mm x 6mm).  

### **Applications:**  
- Microprocessor core voltage regulators.  
- Desktop, workstation, and server power supplies.  
- High-performance DC-DC converters.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics and application notes, refer to the official datasheet.

Application Scenarios & Design Considerations

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

Alternative Part Number

  • NCP5381MNR2G --: Multi-phase PWM buck controller with similar VRM functionality and comparable pinout, suitable as a functional substitute for CPU core power regulation.
  • ADP3198JCPZ-RL --: Multi-phase synchronous buck controller offering similar voltage regulation features and performance class for CPU power applications.
  • TPS40090PWR --: Multi-phase buck controller with comparable control architecture and drive capability, usable as an alternative with minor design adjustments.
  • ISL6561CRZ --: Same ISL6561 controller in the same QFN package without tape-and-reel packing; functionally identical and pin-compatible, now branded Renesas after the Intersil acquisition.
  • ISL6561IRZ --: Same ISL6561 multiphase PWM controller family in an industrial temperature grade, offering equivalent electrical performance with a wider operating range.
  • ISL6566CRZ --: Related Intersil/Renesas multiphase buck controller with comparable voltage-mode architecture and similar pinout, usable as a functional substitute with minor layout review.
