Description and Introduction

Switched Capacitor Voltage Converter 8-SOIC -40 to 85 The LM2662MX/NOPB is a CMOS charge-pump voltage converter manufactured by National Semiconductor (NSC).  

### **Specifications:**  
- **Input Voltage Range:** 1.5V to 5.5V  
- **Output Voltage Options:**  
  - Doubles input voltage (e.g., 3.3V to 6.6V)  
  - Inverts input voltage (e.g., 5V to -5V)  
- **Operating Frequency:** 160kHz (typical)  
- **Output Current:** Up to 40mA (for voltage doubling)  
- **Low Quiescent Current:** 300µA (typical)  
- **Efficiency:** Up to 90%  
- **Package:** SOIC-8  

### **Descriptions:**  
The LM2662MX/NOPB is a switched-capacitor voltage converter that can generate either a doubled or inverted output voltage from a single supply. It requires minimal external components (only two flying capacitors) and operates efficiently across a wide input voltage range.  

### **Features:**  
- **Wide Input Voltage Range:** Supports 1.5V to 5.5V  
- **Low Power Consumption:** 300µA typical quiescent current  
- **No Inductors Required:** Uses only capacitors for voltage conversion  
- **Shutdown Mode:** Reduces current consumption to <1µA  
- **High Efficiency:** Up to 90%  
- **Small Footprint:** SOIC-8 package  

This device is commonly used in battery-powered applications, LCD bias supplies, and portable electronics requiring voltage inversion or doubling.
