Description and Introduction

Switched-Capacitor Voltage Converters The ICL7660ISA is a voltage converter IC manufactured by **Intel**. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Intel  
- **Type:** Voltage Converter (Switched Capacitor)  
- **Input Voltage Range:** 1.5V to 10V  
- **Output Voltage:** Negative of Input (Inverting) or Doubled (Non-Inverting)  
- **Maximum Output Current:** 40mA  
- **Switching Frequency:** ~10kHz (adjustable with external capacitor)  
- **Package:** 8-Pin SOIC (Small Outline Integrated Circuit)  
- **Operating Temperature Range:** -20°C to +85°C  

### **Descriptions:**
- The ICL7660ISA is a monolithic CMOS voltage converter designed to generate a negative supply voltage from a positive input.  
- It can also be configured to double the input voltage.  
- The device operates with minimal external components, requiring only two capacitors for basic operation.  
- It is commonly used in applications requiring a negative voltage rail, such as analog circuits, data acquisition systems, and portable devices.  

### **Features:**
- **Low Power Consumption:** CMOS technology ensures efficient power usage.  
- **Wide Input Voltage Range:** Supports 1.5V to 10V.  
- **No Inductors Required:** Uses switched-capacitor technology, eliminating the need for bulky inductors.  
- **Adjustable Oscillator Frequency:** External capacitor allows frequency adjustment.  
- **High Efficiency:** Typically >95% under optimal conditions.  
- **Pin-Compatible:** Drop-in replacement for similar voltage converters like the MAX1044.  

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