Description and Introduction

SUPER CHARGE PUMP DC-TO-DC VOLTAGE CONVERTER The TC7660SCOA is a DC-DC converter IC manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Manufacturer:** Toshiba  
- **Type:** DC-DC Converter (Charge Pump Voltage Converter)  
- **Input Voltage Range:** 1.5V to 10V  
- **Output Voltage:** Can generate positive or negative voltage (e.g., +2x Vin or -Vin)  
- **Output Current:** Up to 20mA  
- **Switching Frequency:** ~10kHz (typical)  
- **Efficiency:** ~98% (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
- The TC7660SCOA is a monolithic CMOS voltage converter capable of converting a positive input voltage to a corresponding negative output (e.g., +5V to -5V) or doubling the input voltage (e.g., +5V to +10V).  
- It operates without inductors, making it suitable for compact designs.  
- Low power consumption and high efficiency make it ideal for battery-powered applications.  

### **Features:**  
- **Wide Input Voltage Range (1.5V to 10V)**  
- **No External Inductors Required**  
- **Low Power Consumption**  
- **High Efficiency (~98%)**  
- **Simple External Components (Only Capacitors Needed)**  
- **Pin-Compatible with Industry-Standard 7660 Devices**  
- **Available in SOIC-8 Package**  

This information is based on Toshiba’s official documentation for the TC7660SCOA.
