Description and Introduction

White LED Driver and Boost Converter in 3mm x 3mm DFN Package The LT3466EDD-1 is a DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 16V  
- **Output Voltage:** Adjustable (up to 40V)  
- **Switching Frequency:** 1.2MHz  
- **Maximum Output Current:** 1.1A  
- **Package:** DFN-10 (3mm × 3mm)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Efficiency:** Up to 85%  

### **Descriptions:**  
The LT3466EDD-1 is a step-up DC/DC converter designed for applications requiring high output voltages from low input sources. It integrates a power switch, Schottky diode, and control circuitry in a compact package.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 2.7V to 16V input.  
- **High Output Voltage Capability:** Can generate up to 40V.  
- **Internal Power Switch:** Simplifies design with integrated 1.1A, 40V switch.  
- **Fixed Frequency Operation:** 1.2MHz switching frequency reduces external component size.  
- **Soft-Start Function:** Prevents inrush current at startup.  
- **Low Shutdown Current:** <1µA in shutdown mode.  
- **Thermal Protection:** Includes overtemperature shutdown.  

This device is commonly used in applications such as LCD bias supplies, CCD power supplies, and portable electronics.

Description and Introduction

White LED Driver and Boost Converter in 3mm x 3mm DFN Package The LT3466EDD-1 is a monolithic, step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 2.4V to 16V  
- **Output Voltage Range:** Up to 40V  
- **Switching Frequency:** 1.2MHz  
- **Maximum Output Current:** 1.2A (switch current limit)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 10-Lead DFN (3mm × 3mm)  
- **Efficiency:** Up to 85%  
- **Shutdown Current:** <1µA  

### **Descriptions:**  
The LT3466EDD-1 is designed for applications requiring high output voltages from low input sources. It integrates a power switch, Schottky diode, and control circuitry, reducing external component count. The fixed-frequency PWM architecture ensures low noise operation.  

### **Features:**  
- **Integrated Power Switch & Diode**  
- **Soft-Start Function**  
- **Low Shutdown Current (<1µA)**  
- **Current Mode Control for Improved Stability**  
- **Thermal Shutdown Protection**  
- **Small Footprint DFN Package**  

This device is commonly used in LCD bias, CCD power supplies, and other high-voltage step-up applications.
