Description and Introduction

Switched Capacitor Voltage Converter The LM2660MX is a CMOS voltage converter manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Input Voltage Range:** 1.5V to 5.5V  
- **Output Voltage Options:**  
  - Doubles input voltage (step-up)  
  - Inverts input voltage (step-down)  
- **Operating Frequency:** 160kHz (typical)  
- **Output Current:** Up to 40mA (for voltage doubling)  
- **Efficiency:** Up to 90%  
- **Package:** SOIC-8  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LM2660MX is a switched-capacitor voltage converter that can generate either a positive voltage (double the input) or a negative voltage (inverted input). It requires minimal external components, making it suitable for battery-powered applications.  

### **Features:**  
- Low power consumption (170µA typical operating current)  
- No inductors required  
- Can operate in both voltage doubler and inverter modes  
- Low external component count (only two flying capacitors needed)  
- Shutdown mode (reduces current consumption to <1µA)  

This information is based on the manufacturer's datasheet.
