Description and Introduction

Dual Full Function White LED Step-Up Converter with Built-In Schottky Diodes The LT3466EFE#PBF is a dual step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 2.4V to 16V  
- **Output Voltage Range:** Up to 40V (adjustable)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Maximum Output Current:** 1.2A (total for both channels)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead TSSOP (Exposed Pad)  
- **Efficiency:** Up to 87%  

### **Descriptions:**
- The LT3466EFE#PBF is a dual-channel, current-mode, step-up DC/DC converter designed for driving white LEDs or providing regulated voltage outputs.  
- It integrates two independent boost converters with internal power switches, reducing external component count.  
- The device is optimized for compact, battery-powered applications such as LCD backlighting and portable electronics.  

### **Features:**
- **Dual Independent Converters:** Two separate boost regulators in one package.  
- **Internal Power Switches:** Eliminates the need for external MOSFETs.  
- **Low Quiescent Current:** 1.6mA (typical) per channel.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Open LED Protection:** Safeguards against LED failures.  
- **Adjustable Frequency Synchronization:** Allows synchronization to an external clock.  
- **Thermal Shutdown:** Protects the device from overheating.  

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