Description and Introduction

750mA Synchronous Step-Up DC/DC Converters with Reverse-Battery Protection The LTC3499EMS8#PBF is a synchronous step-up DC/DC converter manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 0.5V to 5V  
- **Output Voltage Range:** Up to 5.25V  
- **Switching Frequency:** 1MHz  
- **Maximum Output Current:** 300mA (at 3.3V output from a 1V input)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** MSOP-8  

### **Descriptions:**  
The LTC3499EMS8#PBF is designed for low-input-voltage applications, such as energy harvesting from solar cells or thermoelectric generators. It features a synchronous rectifier for high efficiency and includes an automatic Burst Mode® operation for improved light-load efficiency.  

### **Features:**  
- **Ultra-Low Start-Up Voltage:** As low as 0.5V  
- **Synchronous Rectification:** Improves efficiency  
- **Burst Mode® Operation:** Enhances light-load efficiency  
- **Integrated Soft-Start:** Prevents inrush current  
- **Low Quiescent Current:** 15µA (typical)  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Adjustable Output Voltage:** Via external resistors  

This device is ideal for battery-powered and energy-harvesting applications requiring efficient power conversion from very low input voltages.
