Description and Introduction

ACPI Regulator/Controller for Dual Channel DDR Memory Systems The ISL6537ACR is a power management IC 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  
- **Output Voltage Range:** Adjustable (supports dual-output configurations)  
- **Switching Frequency:** 300kHz (typical)  
- **Output Current:** Supports up to 6A (combined)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 28-lead SOIC  

### **Descriptions:**  
- The ISL6537ACR is a **dual PWM controller** designed for **voltage regulation** in **computing and embedded systems**.  
- It integrates **two synchronous buck controllers** for generating core and I/O voltages in **motherboards, graphics cards, and networking equipment**.  
- Features **voltage tracking** and **soft-start** for controlled power-up sequencing.  

### **Features:**  
- **Dual PWM Controllers:** Independently regulates two output voltages.  
- **Adjustable Outputs:** Supports feedback resistors for custom voltage settings.  
- **Overcurrent Protection (OCP):** Prevents damage from excessive load currents.  
- **Power-Good (PGOOD) Signal:** Monitors output status for system stability.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  

This IC is commonly used in **desktop PCs, servers, and industrial applications** requiring precise voltage regulation.  

*(Note: Always refer to the official datasheet for detailed electrical characteristics and application notes.)*
