Description and Introduction

Two-phase multi-phase buck PWM controller with integrated MOSFET drivers. The ISL6563IR is a PWM controller manufactured by INTERSIL (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** INTERSIL (now Renesas Electronics)  
- **Part Number:** ISL6563IR  
- **Type:** Multi-Phase PWM Controller  
- **Input Voltage Range:** 4.5V to 12V  
- **Output Voltage Range:** Adjustable (0.8V to 5.5V)  
- **Number of Phases:** 1, 2, or 3-phase operation  
- **Switching Frequency:** Adjustable (100kHz to 1MHz)  
- **Duty Cycle Range:** 0% to 100%  
- **Current Sensing:** Precision differential sensing

- **Package:** 28-Lead QFN (Quad Flat No-Lead)  

### **Descriptions:**
The ISL6563IR is a high-performance, multi-phase PWM controller designed for voltage regulator applications, particularly in powering microprocessors and other high-current DC-DC converters. It supports 1-, 2-, or 3-phase operation with adaptive voltage positioning (AVP) and integrated MOSFET drivers.  

### **Features:**
- **Multi-Phase Operation:** Supports 1-, 2-, or 3-phase configurations for scalable current delivery.  
- **Precision Voltage Regulation:** ±1% system accuracy over temperature.  
- **Adaptive Voltage Positioning (AVP):** Optimizes transient response and reduces output capacitance.  
- **Differential Remote Voltage Sensing:** Ensures accurate output voltage regulation.  
- **Programmable Switching Frequency:** Adjustable from 100kHz to 1MHz.  
- **Overcurrent Protection:** Uses MOSFET RDS(ON) sensing or external resistors.  
- **Overvoltage Protection (OVP):** Prevents damage to the load.  
- **Thermal Monitoring:** Includes a thermal warning feature.  
- **Power-Good Output:** Provides a system-ready signal.  

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