Description and Introduction

Switched Capacitor Voltage Converter The LM2665M6 is a CMOS charge-pump voltage converter manufactured by National Semiconductor (now part of Texas Instruments).  

### **Specifications:**  
- **Input Voltage Range:** 1.5V to 5.5V  
- **Output Voltage Options:**  
  - Doubles input voltage (+2x)  
  - Inverts input voltage (-1x)  
- **Output Current:** Up to 40mA (for both modes)  
- **Switching Frequency:** 160kHz (typical)  
- **Low Quiescent Current:** 50µA (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  

### **Descriptions:**  
The LM2665M6 is a switched-capacitor voltage converter capable of generating either a doubled or inverted output voltage from a single supply. It requires minimal external components (only two flying capacitors) and is suitable for battery-powered applications.  

### **Features:**  
- No inductors required  
- Low power consumption  
- Automatic shutdown when disabled  
- Soft-start feature to limit inrush current  
- Thermal shutdown protection  
- Small form factor (SOT-23-6 package)  

This device is commonly used in portable electronics, LCD bias supplies, and other low-power applications requiring voltage conversion.
