Description and Introduction

Switched Capacitor Voltage Doubling Inverter The LM2682M is a dual-output switched capacitor voltage converter manufactured by National Semiconductor (NS). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NS)  
- **Type:** Switched Capacitor Voltage Converter  
- **Output Configuration:** Dual Output (Positive and Negative)  
- **Input Voltage Range:** 2.2V to 5.5V  
- **Output Voltage Options:**  
  - Positive Output: Up to +5.5V  
  - Negative Output: Down to -5.5V  
- **Output Current:** Up to 50mA (dependent on input voltage)  
- **Switching Frequency:** 160kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin SOIC (M)  

### **Descriptions:**  
The LM2682M is a charge-pump-based voltage converter that generates both positive and negative outputs from a single input supply. It is commonly used in applications requiring dual-polarity power supplies, such as operational amplifiers, data converters, and portable electronics.  

### **Features:**  
- **No Inductors Required** (uses only external capacitors)  
- **Low Quiescent Current:** 475µA (typical)  
- **Soft-Start Feature** (reduces inrush current)  
- **Short-Circuit Protection**  
- **Low Output Ripple**  
- **Compact Design** (minimal external components)  

This information is based solely on the manufacturer's datasheet and technical documentation.
