Description and Introduction

1.2A, 750kHz Step-Down Switching Regulator in 2mm x 3mm DFN The LT3493EDCB-3 is a dual output LED driver manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 3V to 30V  
- **Output Voltage Range:** Up to 40V per channel  
- **Switching Frequency:** 1MHz (fixed)  
- **Number of Channels:** 2 (dual output)  
- **Maximum Output Current:** 750mA per channel  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  

### **Descriptions:**
- The LT3493EDCB-3 is a constant-current, step-up DC/DC converter designed for driving LEDs.  
- It includes two independent channels, each capable of driving a string of LEDs with high efficiency.  
- The device operates in a current mode architecture, ensuring stable performance across varying input voltages and LED forward voltages.  
- It features internal compensation and soft-start to minimize external components.  

### **Features:**
- **True Color PWM™ Dimming:** Allows dimming ratios up to 3000:1.  
- **Open LED Protection:** Safeguards against LED open-circuit conditions.  
- **Internal Schottky Diode:** Reduces external component count.  
- **Low Shutdown Current:** <1µA when disabled.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Adjustable Current Limit:** Configurable via an external resistor.
