Description and Introduction

Dual PWM Controller Powering AMD SVI Split-Plane Processors The ISL6329CRZ is a dual-output PWM controller manufactured by Intersil (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V (VCC)  
- **Output Voltage Range:** Adjustable (depends on external components)  
- **Switching Frequency:** Up to 1MHz per phase  
- **Number of Outputs:** Dual (two independent PWM controllers)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 48-Lead QFN (7mm x 7mm)  

### **Descriptions:**  
- The ISL6329CRZ is a high-performance, dual-output PWM controller designed for voltage regulator applications.  
- It supports two independent synchronous buck regulators, making it suitable for multi-phase power supplies.  
- The controller includes adaptive voltage positioning (AVP) for improved transient response.  
- It integrates MOSFET drivers and provides precision voltage regulation.  

### **Features:**  
- **Dual PWM Controllers:** Independent control for two outputs.  
- **Adaptive Voltage Positioning (AVP):** Enhances transient response.  
- **Programmable Switching Frequency:** Up to 1MHz per phase.  
- **Precision Voltage Regulation:** ±0.5% system accuracy over temperature.  
- **Overcurrent Protection:** Uses MOSFET RDS(ON) sensing.  
- **Overvoltage and Undervoltage Protection:** Safeguards the system.  
- **Power-Good Output:** Monitors both regulator outputs.  
- **Soft-Start:** Adjustable for controlled power-up sequencing.  

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