Description and Introduction

CMOS Voltage Converter The ICL7662IBD is a voltage converter IC manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Type:** Switched Capacitor Voltage Converter  
- **Input Voltage Range:** 1.5V to 10V  
- **Output Voltage:** Negative voltage (inverts input voltage)  
- **Output Current Capability:** Up to 20mA  
- **Conversion Efficiency:** Up to 99%  
- **Oscillator Frequency:** Typically 10kHz (internal)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** 8-Pin SOIC (BD)  

### **Descriptions:**
The ICL7662IBD is a CMOS voltage converter designed to generate a negative voltage from a positive input supply. It operates by using an internal oscillator to drive charge-pump capacitors, effectively inverting the input voltage. This IC is commonly used in applications requiring a simple, low-power negative voltage supply without the need for inductors.

### **Features:**
- **Wide Input Voltage Range (1.5V to 10V)**  
- **Low Power Consumption**  
- **No External Inductors Required**  
- **Minimal External Components (Only 2 Capacitors Needed)**  
- **High Efficiency (Up to 99%)**  
- **Pin-Compatible with Industry-Standard 7662 Devices**  
- **Internal Oscillator with No External Timing Components Required**  

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