Description and Introduction

White LED Driver in SC70 with Integrated Schottky The LT3491EDC is a dual monolithic step-down switching regulator manufactured by LINEAR (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 3.6V to 36V  
- **Output Voltage Range:** Adjustable from 1.25V to 35V  
- **Output Current:** Up to 1.1A per channel  
- **Switching Frequency:** 1.2MHz (fixed)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** DFN-10 (3mm × 3mm)  

### **Descriptions:**
- The LT3491EDC is a dual-channel DC/DC converter with independent control for each channel.  
- It includes internal power switches, minimizing external component count.  
- Designed for high efficiency and compact power supply solutions.  
- Suitable for automotive, industrial, and battery-powered applications.  

### **Features:**
- **Dual Independent Regulators:** Two step-down converters in one package.  
- **Synchronous Rectification:** Improves efficiency.  
- **Low Dropout Operation:** Allows high duty cycle operation.  
- **Adjustable Soft-Start:** Reduces inrush current.  
- **Current Mode Control:** Ensures stable operation.  
- **Short-Circuit Protection:** Enhances reliability.  
- **Thermal Shutdown:** Prevents overheating.  

The LT3491EDC is optimized for space-constrained applications requiring high efficiency and wide input voltage range.

- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 6-Lead DFN (3mm × 3mm)  

### **Description:**  
The LT3491EDC is a dual monolithic step-down DC/DC converter designed to drive high-current LEDs efficiently. It includes internal power switches and Schottky diodes, reducing external component count.  

### **Features:**  
- Dual independent LED drivers in a single package  
- Wide input voltage range supports various power sources  
- Constant current regulation for LED brightness control  
- Integrated Schottky diodes for compact design  
- Low dropout operation for extended battery life  
- Thermal shutdown protection  
- Small footprint DFN package  

This information is based solely on the LT3491EDC datasheet from Linear Technology (Analog Devices).
