Description and Introduction

LM2751 Regulated 2X, 1.5X Switched Capacitor White LED Driver The LM2751SD-A is a switching regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** Adjustable (via external resistors)  
- **Switching Frequency:** 1.6MHz (typical)  
- **Output Current:** Up to 300mA  
- **Efficiency:** Up to 90%  
- **Package:** 10-pin LLP (Leadless Leadframe Package)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Features:** Soft-start, thermal shutdown, and current limit protection  

### **Descriptions:**  
The LM2751SD-A is a high-efficiency, step-down DC-DC converter designed for low-power applications. It integrates a synchronous rectifier for improved efficiency and operates at a fixed switching frequency of 1.6MHz, allowing for small external components.  

### **Features:**  
- **High Efficiency:** Up to 90%  
- **Low Quiescent Current:** 40µA (typical)  
- **Adjustable Output Voltage**  
- **Integrated Synchronous Rectifier**  
- **Soft-Start Function**  
- **Thermal Shutdown Protection**  
- **Current Limit Protection**  
- **Compact 10-pin LLP Package**  

This device is suitable for battery-powered applications, portable electronics, and other low-power systems requiring efficient voltage conversion.
