Description and Introduction

VRM8.5 Dual PWM and Dual Linear Power System Controller The ISL6523CB is a power supply controller manufactured by Intersil (now part of Renesas Electronics). Below are the factual details about its specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable from 0.9V to 5.5V  
- **Switching Frequency:** 300kHz (fixed)  
- **Maximum Output Current:** 20A (with external MOSFETs)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-lead SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
The ISL6523CB is a synchronous buck PWM controller designed for high-efficiency DC-DC voltage regulation. It is commonly used in applications requiring precise voltage regulation, such as power supplies for microprocessors, FPGAs, and other digital ICs.  

### **Features:**  
- **Voltage Mode Control:** Provides stable output voltage regulation.  
- **Integrated MOSFET Drivers:** Supports external N-channel MOSFETs.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Overcurrent Protection:** Uses external current sensing for fault detection.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within input voltage range.  
- **Power Good Output:** Monitors output voltage status.  

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