Description and Introduction

Multi-Phase PWM Controller with Precision rDS(ON) or DCR Current Sensing for VR10.X Application The ISL6565ACRZ 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 information:

### **Specifications:**
- **Manufacturer:** INTERSIL (now Renesas Electronics)  
- **Part Number:** ISL6565ACRZ  
- **Package:** 40-Lead QFN (Quad Flat No-Lead)  
- **Input Voltage Range:** 5V to 12V (VCC)  
- **Output Voltage Range:** Adjustable (down to 0.8V)  
- **Number of Phases:** 1, 2, or 3-phase operation  
- **Switching Frequency Range:** 80kHz to 1MHz (per phase)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**
- The ISL6565ACRZ is a high-performance, multi-phase PWM controller designed for precision voltage regulation in power supplies, particularly for microprocessors and other high-current applications.  
- It supports 1-, 2-, or 3-phase operation with integrated MOSFET drivers or external drivers.  
- It features adaptive voltage positioning (AVP) for improved transient response and efficiency.  

### **Features:**
- **Precision Voltage Regulation:** ±1% system accuracy over temperature.  
- **Adaptive Voltage Positioning (AVP):** Reduces output capacitance requirements.  
- **Dynamic Phase Control:** Automatically adjusts the number of active phases for efficiency optimization.  
- **Programmable Switching Frequency:** Adjustable from 80kHz to 1MHz per phase.  
- **Overcurrent Protection:** Uses MOSFET rDS(ON) sensing for accurate current monitoring.  
- **Overvoltage and Undervoltage Protection:** Safeguards the load.  
- **Power-Good Output:** Monitors output voltage status.  
- **Differential Remote Sensing:** Compensates for PCB trace resistance.  
- **Soft-Start and Soft-Stop:** Reduces inrush current.  

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