Description and Introduction

General Purpose, Gated Oscillator Based, DC/DC Boost Converter The LM2623LDX is a step-up DC-DC converter manufactured by Texas Instruments (NS). Below are the factual details about its specifications, descriptions, and features:

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

### **Descriptions:**  
The LM2623LDX is a high-efficiency, low-voltage, step-up DC-DC converter designed for battery-powered applications. It integrates a power MOSFET and provides a compact solution for boosting low input voltages to higher output levels.  

### **Features:**  
- **Low Start-Up Voltage:** Operates down to 0.8V  
- **Integrated Power MOSFET:** Reduces external component count  
- **Adjustable Output Voltage:** Via external resistor divider  
- **Soft-Start Function:** Prevents inrush current  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Low Quiescent Current:** 17µA (typical) in shutdown mode  

This information is sourced from the official Texas Instruments datasheet for the LM2623LDX.
