Description and Introduction

750mA Synchronous Step-Up DC/DC Converters with Reverse-Battery Protection The LTC3499BEDD is a product from Linear Technology (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Linear Technology (LT)  

### **Part Number:**  
LTC3499BEDD  

### **Description:**  
The LTC3499BEDD is a high-efficiency, synchronous step-up DC/DC converter designed for low input voltage applications. It is optimized for powering white LEDs or providing a regulated voltage output from single-cell or dual-cell alkaline/NiMH battery inputs.  

### **Key Features:**  
- **Input Voltage Range:** 0.8V to 5.5V  
- **Output Voltage:** Adjustable up to 5V  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 90%  
- **Synchronous Rectification:** Improves efficiency and eliminates the need for an external Schottky diode  
- **Low Quiescent Current:** 20µA (typical)  
- **Integrated Soft-Start:** Reduces inrush current  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Small Package:** 10-Lead DFN (3mm × 3mm)  

### **Applications:**  
- White LED backlighting  
- Single or dual-cell battery-powered devices  
- Portable electronics  
- Energy harvesting systems  

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