Description and Introduction

Multi-Phase PWM Controller with Linear 6-bit DAC Capable of Precision rDS(ON) or DCR Differential Current Sensing The ISL6564CR is a multi-phase PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** INTERSIL (now Renesas Electronics)  
- **Part Number:** ISL6564CR  
- **Type:** Multi-Phase PWM Controller  
- **Input Voltage Range:** 4.5V to 12V  
- **Output Voltage Range:** Adjustable (typically 0.8V to 5.5V)  
- **Number of Phases:** 2, 3, or 4-phase operation  
- **Switching Frequency:** Adjustable up to 1.5MHz per phase  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-Lead QFN (Quad Flat No-Lead)  

### **Descriptions:**  
- The ISL6564CR is a high-performance multi-phase PWM controller designed for voltage regulation in high-current applications such as CPUs, GPUs, and memory power supplies.  
- It supports 2, 3, or 4-phase operation with adaptive phase balancing for improved thermal performance.  
- The controller includes overvoltage, undervoltage, and overcurrent protection features.  

### **Features:**  
- **Precision Multi-Phase Core Regulator:** Ensures accurate voltage regulation for high-current loads.  
- **Adaptive Phase Balancing:** Optimizes efficiency and thermal performance by dynamically adjusting phase contributions.  
- **Programmable Switching Frequency:** Up to 1.5MHz per phase.  
- **Differential Remote Voltage Sensing:** Compensates for PCB trace resistance.  
- **Overcurrent Protection (OCP):** Monitors and protects against excessive current.  
- **Overvoltage Protection (OVP) & Undervoltage Protection (UVP):** Safeguards the load from voltage extremes.  
- **Power-Good Output:** Provides a signal indicating stable output voltage.  
- **Adjustable Soft-Start:** Controls inrush current during startup.  

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