Description and Introduction

1A Switched Capacitor Flash LED Driver with I2C Compatible Interface 12-WSON -30 to 85 The LM2759SDX/NOPB is a switched capacitor voltage converter manufactured by National Semiconductor (now part of Texas Instruments).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** 5V (regulated)  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 1MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Pin WSON (3mm x 3mm)  
- **Features:**  
  - No inductors required  
  - Low output ripple  
  - Soft-start for controlled inrush current  
  - Thermal shutdown protection  
  - Short-circuit protection  

### **Descriptions and Features:**  
The LM2759SDX/NOPB is a high-efficiency, fixed 5V output switched capacitor voltage doubler. It is designed for applications requiring a regulated 5V supply from a lower input voltage (2.7V to 5.5V). The device uses a charge-pump architecture, eliminating the need for bulky inductors.  

Key features include:  
- **Compact Design:** Small footprint with a 10-pin WSON package.  
- **High Efficiency:** Optimized for power-sensitive applications.  
- **Integrated Protection:** Includes thermal shutdown and short-circuit protection.  
- **Low Noise Operation:** Minimizes output ripple for sensitive circuits.  

This converter is commonly used in portable electronics, battery-powered systems, and other applications requiring efficient step-up voltage conversion.
