Description and Introduction

White LED Driver in SC70 with Integrated Schottky The LT3491EDC#TRMPBF is a dual output LED driver manufactured by Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Manufacturer:**  
- **Linear Technology (now part of Analog Devices)**  

### **Part Number:**  
- **LT3491EDC#TRMPBF**  

### **Description:**  
- The LT3491EDC#TRMPBF is a dual output, step-down DC/DC converter designed specifically for driving LEDs. It operates from a wide input voltage range and provides constant current to two independent LED strings.  

### **Key Features:**  
1. **Dual Independent Outputs:**  
   - Drives two separate LED strings with independent current control.  

2. **Wide Input Voltage Range:**  
   - **4V to 30V** input range.  

3. **High Efficiency:**  
   - Uses a synchronous rectification architecture for improved efficiency.  

4. **PWM Dimming Control:**  
   - Supports **1000:1** PWM dimming ratio for precise brightness adjustment.  

5. **Analog Dimming Control:**  
   - Allows brightness adjustment via an analog voltage input.  

6. **Integrated Power Switches:**  
   - Includes internal **1.5A** power switches for each channel.  

7. **Frequency Adjustable (200kHz to 2.1MHz):**  
   - Allows optimization for efficiency or component size.  

8. **Open LED Protection:**  
   - Detects and protects against open LED conditions.  

9. **Thermal Shutdown:**  
   - Prevents overheating with built-in thermal protection.  

10. **Small Package:**  
    - Available in a **DFN-10 (3mm × 3mm)** package.  

### **Applications:**  
- LED backlighting for LCD displays  
- Automotive LED lighting  
- General-purpose LED drivers  

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