Description and Introduction

Switched Capacitor Voltage Converter The LM2661MM is a charge pump voltage converter manufactured by Texas Instruments (NS). Here are its key specifications, descriptions, and features:

### **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)  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 160kHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin VSSOP (MM)  

### **Descriptions:**
The LM2661MM is a CMOS charge pump DC-DC converter that generates a regulated output voltage by either doubling or inverting the input voltage. It requires minimal external components (only two flying capacitors and two bypass capacitors) and is suitable for low-power applications.  

### **Features:**
- **Low Power Consumption:** 300μA typical operating current  
- **No Inductors Required:** Uses only capacitors for voltage conversion  
- **Low Output Impedance:** Ensures stable voltage regulation  
- **Shutdown Mode:** Reduces current consumption to <1μA  
- **Wide Input Voltage Range:** Supports battery-powered applications  
- **Internal Oscillator:** No external timing components needed  

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