Description and Introduction

Switched Capacitor Voltage Doubling Inverter 8-VSSOP -40 to 85 The LM2682MMX/NOPB is a switched capacitor voltage doubler manufactured by National Semiconductor (NSC). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NSC)  
- **Type:** Switched Capacitor Voltage Doubler  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage:** Up to 2 × VIN (adjustable)  
- **Output Current:** Up to 50mA  
- **Switching Frequency:** 160kHz (typical)  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (MM)  

### **Descriptions:**  
- The LM2682MMX/NOPB is a charge pump DC-DC converter that doubles the input voltage.  
- It requires only two external flying capacitors for operation.  
- Low quiescent current (typically 135µA) makes it suitable for battery-powered applications.  
- Features a shutdown mode to reduce power consumption further.  

### **Features:**  
- **Low Noise Operation:** Minimizes output ripple.  
- **No Inductors Required:** Simplifies design compared to traditional boost converters.  
- **Shutdown Mode:** Reduces current consumption to 1µA (typical).  
- **Soft-Start Circuitry:** Prevents excessive inrush current.  
- **Thermal Shutdown Protection:** Safeguards the device from overheating.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to the official documentation.
