Description and Introduction

General Purpose, Gated Oscillator Based, DC/DC Boost Converter The LM2623LD is a step-up DC-DC switching regulator manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Input Voltage Range:** 0.8V to 14V  
- **Output Voltage:** Adjustable from 1.24V to 14V  
- **Switching Frequency:** 300kHz (typical)  
- **Maximum Output Current:** Up to 1.5A (depending on input/output conditions)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin WSON (3mm x 3mm)  

### **Descriptions:**  
The LM2623LD is a high-efficiency, low-voltage step-up DC-DC converter designed for battery-powered applications. It integrates a power MOSFET and supports low input voltages, making it suitable for single-cell or dual-cell battery systems.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.8V  
- **Integrated Power MOSFET:** Reduces external component count  
- **Adjustable Output Voltage:** Via external resistors  
- **Soft-Start Function:** Prevents inrush current  
- **Undervoltage Lockout (UVLO):** Ensures proper operation at low input voltages  
- **Thermal Shutdown Protection:** Prevents overheating  

This information is based on the manufacturer's datasheet.
