Description and Introduction

Switched Capacitor Voltage Converter The LM2660MMX is a CMOS charge-pump voltage converter manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Input Voltage Range:** 1.5V to 5.5V  
- **Output Voltage Options:**  
  - Doubles input voltage (e.g., 5V input → 10V output)  
  - Inverts input voltage (e.g., 5V input → -5V output)  
- **Output Current:** Up to 40mA  
- **Operating Frequency:** 160kHz (typical)  
- **Efficiency:** Up to 90%  
- **Low Quiescent Current:** 300µA (typical)  
- **Package:** 8-pin VSSOP (MMX)  

### **Descriptions & Features:**  
- **Charge-Pump Architecture:** Does not require inductors, making it compact.  
- **Wide Input Voltage Range:** Supports battery-powered applications.  
- **Low Power Consumption:** Ideal for portable devices.  
- **Automatic Disconnect:** Minimizes current draw when disabled.  
- **Applications:**  
  - Voltage doubling/inversion for LCD bias, RS-232, and portable instruments.  
  - Power supply generation in low-power systems.  

This device is designed for space-constrained applications requiring efficient voltage conversion.
