Description and Introduction

Multi-Phase PWM Controller The ISL6569ACR is a multi-phase PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Manufacturer:** INTERSIL (now Renesas Electronics)  
- **Part Number:** ISL6569ACR  
- **Type:** Multi-phase PWM Controller  
- **Input Voltage Range:** 4.5V to 12V (VCC)  
- **Output Voltage Range:** Adjustable (supports VRM 9.x, VRM 10.x, and AMD Hammer specifications)  
- **Number of Phases:** Configurable (1 to 4 phases)  
- **Switching Frequency:** Adjustable (up to 1.5MHz per phase)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 40-Lead QFN (6mm x 6mm)  

### **Descriptions:**
- The ISL6569ACR is a high-performance, multi-phase PWM controller designed for voltage regulation in high-current applications, such as microprocessors and GPUs.  
- It supports adaptive phase control, enabling dynamic adjustment of the number of active phases to optimize efficiency under varying load conditions.  
- The controller integrates MOSFET drivers and provides precision voltage regulation with differential remote sensing.  

### **Features:**
- **Multi-Phase Operation:** Configurable for 1 to 4 phases.  
- **Adaptive Phase Control:** Automatically adjusts active phases for efficiency.  
- **Precision Voltage Regulation:** ±0.5% system accuracy over temperature.  
- **Differential Remote Sensing:** Compensates for PCB trace losses.  
- **Programmable Switching Frequency:** Up to 1.5MHz per phase.  
- **Overcurrent Protection:** Uses MOSFET RDS(ON) sensing.  
- **Overvoltage and Undervoltage Protection (OVP/UVP).**  
- **Thermal Monitoring:** Supports external temperature sensing.  
- **Power-Good Output:** Indicates stable output voltage.  

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