Description and Introduction

Switched Capacitor Voltage Converter The LM2664M6X is a switched capacitor voltage converter manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Input Voltage Range:** 1.5V to 5.5V  
- **Output Voltage Options:**  
  - Inverts input voltage (e.g., +5V to -5V)  
  - Doubles input voltage (e.g., +5V to +10V)  
- **Output Current:** Up to 40mA  
- **Switching Frequency:** 160kHz (typical)  
- **Low Quiescent Current:** 300µA (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  

### **Descriptions:**  
The LM2664M6X is a CMOS charge-pump voltage converter that can generate a negative voltage (inverting mode) or double the input voltage (doubling mode). It requires minimal external components (only two flying capacitors) and is ideal for low-power applications.  

### **Features:**  
- **Wide Input Voltage Range (1.5V to 5.5V)**  
- **No Inductors Required**  
- **Low External Component Count**  
- **Low Power Consumption**  
- **Shutdown Mode (Reduces Current to 1µA)**  
- **Thermal Shutdown Protection**  
- **Space-Saving SOT-23-6 Package**  

This device is commonly used in battery-powered systems, portable instruments, and other applications requiring voltage inversion or doubling.
