Description and Introduction

Switched Capacitor Voltage Converter The LMC7660IM is a CMOS voltage converter manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NSC)  
- **Type:** CMOS Voltage Converter (Charge Pump)  
- **Package:** 8-Pin SOIC  
- **Input Voltage Range:** 1.5V to 10V  
- **Output Voltage:** Negative of Input Voltage (Inverts Input)  
- **Output Current:** Up to 40mA (typical)  
- **Switching Frequency:** ~10kHz (typical)  
- **Quiescent Current:** ~0.3mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The LMC7660IM is a monolithic CMOS voltage converter designed to generate a negative voltage from a positive input supply. It operates as a charge pump, eliminating the need for inductors. It is commonly used for generating negative bias voltages in low-power applications.  

### **Features:**  
- **No Inductors Required** – Uses only external capacitors for operation.  
- **Wide Input Voltage Range** – Supports 1.5V to 10V.  
- **Low Power Consumption** – Ideal for battery-operated devices.  
- **High Efficiency** – Up to 98% (typical).  
- **Simple Circuit Implementation** – Requires only two external capacitors.  
- **Pin-Compatible with Industry-Standard 7660 Devices**  

This information is strictly based on the manufacturer's datasheet and technical documentation.
