Description and Introduction

Three-Phase Buck PWM Controller with Integrated MOSFET Drivers and Light Load Efficiency Enhancements for Intel VR11.1 Applications The ISL6333CRZ is a PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** INTERSIL (Renesas Electronics)  
- **Part Number:** ISL6333CRZ  
- **Type:** PWM Controller  
- **Output Phases:** 2, 3, 4, 5, or 6 phases (configurable)  
- **Input Voltage Range (VIN):** 4.5V to 24V  
- **Output Voltage Range (VOUT):** 0.6V to 5.5V (adjustable)  
- **Switching Frequency:** 200kHz to 1MHz (adjustable)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 40-lead QFN (6x6 mm)  

### **Descriptions:**  
The ISL6333CRZ is a multi-phase PWM controller designed for high-performance voltage regulation in power supply applications. It supports dynamic phase shedding for improved efficiency across load conditions. It is commonly used in server, desktop, and embedded systems requiring precise voltage regulation.  

### **Features:**  
- **Multi-Phase Operation:** Configurable for 2 to 6 phases.  
- **Dynamic Phase Shedding:** Enhances efficiency by disabling unused phases at light loads.  
- **Precision Voltage Regulation:** ±0.5% system accuracy over temperature.  
- **Differential Remote Sensing:** Compensates for PCB trace resistance.  
- **Adaptive Voltage Positioning (AVP):** Reduces output capacitance requirements.  
- **Programmable Switching Frequency:** 200kHz to 1MHz.  
- **Overcurrent Protection (OCP):** Monitors and protects against excessive current.  
- **Overvoltage Protection (OVP) & Undervoltage Protection (UVP):** Safeguards the system.  
- **Power Good Indicator:** Signals when output voltage is within regulation.  

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