Description and Introduction

Single-Phase Core Regulator for IMVP-6 Mobile CPUs The ISL6261IRZ is a high-performance 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:** ISL6261IRZ  
- **Package:** 40-Lead QFN (6x6mm)  
- **Input Voltage Range:** 4.5V to 24V  
- **Output Voltage Range:** Adjustable (supports VR11/VR10.x specifications)  
- **Switching Frequency:** Adjustable (300kHz to 1MHz)  
- **Number of Phases:** 1 or 2-phase operation  
- **Current Sensing:** Lossless inductor DCR or resistor-based  
- **Efficiency:** High efficiency with adaptive voltage positioning (AVP)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The ISL6261IRZ is a synchronous buck PWM controller designed for high-performance microprocessor core voltage regulation. It supports Intel VR11/VR10.x specifications and provides precise voltage regulation with adaptive voltage positioning (AVP). It is optimized for single or dual-phase operation, making it suitable for notebook and desktop applications.  

### **Features:**  
- **Dual-Mode PWM Control:** Supports 1-phase or 2-phase operation.  
- **Adaptive Voltage Positioning (AVP):** Enhances transient response and reduces output capacitance.  
- **Lossless Current Sensing:** Uses inductor DCR or external resistor for accurate current monitoring.  
- **Programmable Switching Frequency:** Adjustable from 300kHz to 1MHz.  
- **Dynamic Phase Shedding:** Improves light-load efficiency.  
- **Overvoltage, Undervoltage, and Overcurrent Protection:** Ensures system safety.  
- **Differential Remote Sensing:** Compensates for PCB trace resistance.  
- **Power Good Indicator:** Provides system status monitoring.  

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