Description and Introduction

Voltage Inverter, +5 to ?V, Input Voltage 1.5-10V, or Voltage Doubler to 18.6V The ICL7660 is a voltage converter manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Supply Voltage Range:** 1.5V to 10V  
- **Output Voltage:** Negative supply voltage (inverts input voltage)  
- **Output Current:** Up to 40mA (depending on conditions)  
- **Power Conversion Efficiency:** Typically 99.9%  
- **Operating Frequency:** ~10kHz (internal oscillator)  
- **External Clock Support:** Yes (can be synchronized with an external clock)  
- **Package Options:** 8-Pin DIP, SOIC  

### **Descriptions:**
- The ICL7660 is a **CMOS voltage converter** designed to generate a negative voltage from a positive input supply.  
- It operates as a **charge-pump voltage inverter**, eliminating the need for inductors.  
- Commonly used in **dual-supply systems** where a negative voltage is required from a single positive supply.  

### **Features:**
- **Simple Voltage Inversion:** Converts +V to -V with minimal external components.  
- **Low Power Consumption:** CMOS technology ensures low quiescent current.  
- **No Inductors Required:** Uses only capacitors for charge pumping.  
- **Wide Operating Voltage Range:** Supports 1.5V to 10V inputs.  
- **External Clock Capability:** Allows synchronization with an external oscillator.  
- **High Efficiency:** Near-lossless charge transfer for efficient conversion.  

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