Description and Introduction

CMOS Voltage Converter The ICL7662IPA is a voltage converter IC manufactured by Harris Semiconductor (now part of Intersil/Renesas). Below are the factual details about its specifications, descriptions, and features:

### **Manufacturer:**  
Harris Semiconductor (now part of Intersil/Renesas)  

### **Part Number:**  
ICL7662IPA  

### **Description:**  
The ICL7662IPA is a monolithic, CMOS voltage converter designed to generate a negative voltage from a positive input supply. It can also function as a voltage doubler or inverter.  

### **Key Features:**  
- **Input Voltage Range:** 1.5V to 10V  
- **Output Voltage:** Negative of input voltage (for inverter mode) or double the input voltage (for doubler mode)  
- **High Efficiency:** Up to 99%  
- **Low Power Consumption:** Typically 0.2mA  
- **No External Diodes Required:** Internal charge pump circuitry  
- **Operating Temperature Range:** -20°C to +85°C  
- **Package Type:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Applications:**  
- Voltage inversion (positive to negative conversion)  
- Voltage doubling  
- Power supply generation in portable devices  
- Battery-powered systems  

### **Pin Configuration (8-Pin PDIP):**  
1. **CAP+** – Positive terminal of the flying capacitor  
2. **GND** – Ground reference  
3. **CAP-** – Negative terminal of the flying capacitor  
4. **VOUT** – Negative output voltage (inverter mode) or doubled output (doubler mode)  
5. **LV** – Low-voltage operation control (tied to GND for standard operation)  
6. **OSC** – Oscillator control (external capacitor for frequency adjustment)  
7. **NC** – No connection  
8. **V+** – Positive supply input  

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