Description and Introduction

Four-Phase Buck PWM Controller with Integrated MOSFET Drivers and I2C Interface for Intel VR10, VR11, and AMD Applications The **ISL6322CRZ** is a dual-output PWM controller manufactured by **INTERSIL** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V (VCC)  
- **Output Voltage Range:** Adjustable (depends on external components)  
- **Switching Frequency:** Up to 1MHz (programmable)  
- **Number of Outputs:** Dual (two independent PWM controllers)  
- **Topology:** Synchronous Buck  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 32-Lead QFN (5mm x 5mm)  

### **Descriptions:**  
- Designed for **high-efficiency DC-DC voltage regulation** in computing and embedded systems.  
- Supports **voltage positioning** for improved transient response.  
- Features **adaptive non-overlap gate drive** to prevent shoot-through in synchronous MOSFETs.  
- Includes **integrated MOSFET drivers** (up to 2A sink/source capability).  

### **Features:**  
- **Dual PWM controllers** for independent regulation of two outputs.  
- **Programmable switching frequency** (up to 1MHz).  
- **Precision voltage reference** (±1% over temperature).  
- **Overcurrent protection** (OCP) with adjustable thresholds.  
- **Power-good indicators** for each output.  
- **Soft-start and soft-stop** for controlled power sequencing.  
- **Thermal shutdown** protection.
