Description and Introduction

Switched Capacitor Voltage Doubling Inverter The LM2682MM is a dual-output switched capacitor voltage converter manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Dual Output Voltages:**  
  - Positive Output: Up to +5.5V  
  - Negative Output: Down to -5.5V  
- **Output Current:** Up to 50mA (combined)  
- **Switching Frequency:** 160kHz (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-pin MSOP (MM)  

### **Descriptions and Features:**  
- Provides regulated positive and negative outputs from a single input supply.  
- Uses switched capacitor technology for efficient voltage conversion.  
- No inductors required, reducing board space and cost.  
- Low quiescent current (typically 0.7mA).  
- Integrated soft-start feature to limit inrush current.  
- Short-circuit and thermal protection.  
- Suitable for battery-powered applications, LCD bias supplies, and portable devices.  

The LM2682MM is designed for applications requiring dual-rail power supplies from a single input source.
