Description and Introduction

PWM Controller and Triple Linear Reg, VRM8.5, 5-Bit DAC, Core ?%, Linears ?% The ISL6524 is a PWM controller manufactured by **INTERSIL** (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on available factual information:  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable (via external feedback resistors)  
- **Switching Frequency:** 300kHz (fixed)  
- **Duty Cycle Range:** 0% to 100%  
- **Output Current:** Supports external MOSFETs (current handling depends on external components)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-Lead SOIC  

### **Descriptions:**  
- The ISL6524 is a **single-phase synchronous buck PWM controller** designed for DC-DC voltage regulation.  
- It is commonly used in **power supply applications**, such as **CPU core voltage regulators**, **memory power supplies**, and **general-purpose DC-DC converters**.  
- The controller includes **overvoltage protection (OVP)**, **undervoltage lockout (UVLO)**, and **soft-start functionality**.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency by reducing power loss.  
- **Integrated MOSFET Drivers:** Supports high-side and low-side N-channel MOSFETs.  
- **Adjustable Soft-Start:** Prevents inrush current at startup.  
- **Precision Reference Voltage:** 1.0V ±1% accuracy.  
- **Overvoltage Protection (OVP):** Shuts down the output if voltage exceeds a safe threshold.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within input voltage range.  
- **Fixed-Frequency Operation:** 300kHz PWM for stable performance.  

This information is based on the **datasheet** and technical documentation from **INTERSIL** (now Renesas Electronics). For exact performance details, refer to the official datasheet.
