Description and Introduction

Low Input Voltage, Step-Up DC-DC The LM2621MMX is a switching regulator IC manufactured by Texas Instruments (NS). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2V to 14V  
- **Output Voltage Range:** Adjustable from 1.24V to 14V  
- **Switching Frequency:** 300kHz (typical)  
- **Maximum Output Current:** 1.5A  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-pin VSSOP (MSOP)  

### **Descriptions:**  
The LM2621MMX is a high-efficiency, step-up DC-DC switching regulator designed for battery-powered and low-voltage applications. It integrates a power MOSFET and provides a regulated output voltage from a low input supply.  

### **Features:**  
- **Low Start-up Voltage:** Operates down to 2V  
- **Integrated Power MOSFET:** Reduces external component count  
- **Adjustable Output Voltage:** Via external resistors  
- **Low Quiescent Current:** 40µA (typical)  
- **Soft-Start Function:** Prevents inrush current  
- **Thermal Shutdown Protection:** Prevents overheating  
- **Undervoltage Lockout (UVLO):** Ensures proper operation  

This information is strictly based on the manufacturer's datasheet.
