Description and Introduction

1A Switched Capacitor Flash LED Driver with I2C Compatible Interface The LM2759SD 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 100mA  
- **Efficiency:** Up to 90%  
- **Package:** 10-pin LLP (Leadless Leadframe Package)  
- **Operating Temperature Range:** -40°C to +85°C  

**Descriptions:**  
The LM2759SD is a high-efficiency, fixed-frequency step-up DC-DC converter designed for low-power applications. It integrates a power switch and provides a regulated output voltage from a low input supply.  

**Features:**  
- Fixed-frequency PWM operation  
- Low shutdown current (<1µA)  
- Internal soft-start  
- Over-temperature protection  
- Small footprint due to LLP package  

This information is based on the manufacturer's datasheet.
