Description and Introduction

Wide Input Range Dual PWM Controller with DDR Option The ISL6539CA-T is a power management IC manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** INTERSIL (now Renesas Electronics)  
- **Part Number:** ISL6539CA-T  
- **Type:** Dual PWM Controller  
- **Input Voltage Range:** 4.5V to 5.5V  
- **Output Voltage Range:** Adjustable (supports 0.9V to 5.5V)  
- **Switching Frequency:** 200kHz to 1MHz (adjustable)  
- **Number of Outputs:** 2 (dual-channel)  
- **Duty Cycle:** Up to 100%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SOIC  

### **Descriptions:**
The ISL6539CA-T is a high-efficiency, dual PWM controller designed for regulating voltage in power supply applications. It provides precise voltage regulation for two independent outputs, making it suitable for motherboards, graphics cards, and other systems requiring multiple power rails.

### **Features:**
- **Dual PWM Controllers:** Independently controls two synchronous buck regulators.  
- **Adjustable Output Voltage:** Supports a wide range of output voltages.  
- **Programmable Switching Frequency:** Allows optimization for efficiency or size.  
- **Integrated MOSFET Drivers:** Reduces external component count.  
- **Overvoltage Protection (OVP):** Safeguards against excessive output voltage.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Power-Good Output:** Monitors output voltage status.  
- **Soft-Start Function:** Prevents inrush current during startup.  

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