Description and Introduction

CMOS Voltage Converters The ICL7662EBA is a voltage converter manufactured by Intersil (now part of Renesas Electronics). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Intersil (now Renesas Electronics)  
- **Part Number:** ICL7662EBA  
- **Type:** Switched-Capacitor Voltage Converter  
- **Input Voltage Range:** 1.5V to 10V  
- **Output Voltage:** Negative or Doubled Input Voltage (depending on configuration)  
- **Output Current:** Up to 20mA  
- **Switching Frequency:** ~10kHz (adjustable with external capacitor)  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The ICL7662EBA is a CMOS-based voltage converter capable of generating negative or doubled voltages from a single positive supply.  
- It operates as a charge pump, using external capacitors to transfer charge and invert or double the input voltage.  
- It is commonly used in applications requiring a negative supply rail or a higher voltage from a low-voltage source.  

### **Features:**  
- **Low Power Consumption:** CMOS technology ensures minimal power loss.  
- **No Inductors Required:** Uses only external capacitors for operation.  
- **Wide Input Voltage Range:** Supports 1.5V to 10V inputs.  
- **Adjustable Oscillator Frequency:** External capacitor allows frequency tuning.  
- **High Efficiency:** Typically >90% conversion efficiency.  
- **Pin-Compatible Upgrade:** Improved version of the ICL7660 with better performance.  

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