Description and Introduction

Ultralow Voltage Step-Up Converter and Power Manager The LTC3108EGN is a highly integrated DC/DC converter designed for energy harvesting applications. Below are the factual specifications, descriptions, and features from the manufacturer's knowledge base:

### **Manufacturer:**  
- **Linear Technology (now part of Analog Devices)**  

### **Part Number:**  
- **LTC3108EGN**  

### **Description:**  
- The LTC3108EGN is an ultralow voltage step-up converter and power manager optimized for harvesting energy from low-voltage, high-impedance sources such as thermoelectric generators (TEGs), thermopiles, and small solar cells.  

### **Key Features:**  
1. **Ultralow Input Voltage Operation:**  
   - Can start up with input voltages as low as **20mV**.  
   - Operates from input voltages ranging from **20mV to 500mV**.  

2. **High Efficiency:**  
   - Integrated synchronous rectification for improved efficiency.  
   - Up to **96% efficiency** in boost mode.  

3. **Integrated Power Management:**  
   - Automatic power path management for charging a storage capacitor or battery.  
   - Selectable output voltages (**2.35V, 3.3V, 4.1V, or 5V**).  

4. **Low Quiescent Current:**  
   - **6µA** typical quiescent current in sleep mode.  

5. **Energy Storage Support:**  
   - Can charge a **supercapacitor or rechargeable battery** for energy storage.  

6. **Output Regulation:**  
   - Provides regulated output voltages for powering low-power electronics.  

7. **Package:**  
   - **16-Lead SSOP (GN) package**.  

8. **Applications:**  
   - Energy harvesting from thermoelectric generators (TEGs).  
   - Wireless sensor nodes.  
   - Low-power IoT devices.  
   - Battery-less systems.  

### **Additional Notes:**  
- The LTC3108EGN includes a **cold-start circuit** to initiate operation from extremely low input voltages.  
- It features **maximum power point control (MPPC)** for optimizing energy extraction from the source.  

This information is based on the manufacturer's datasheet and technical documentation. For detailed electrical characteristics, refer to the official datasheet.
