Description and Introduction

CMOS Voltage Converters The ICL7660CBA-T is a voltage converter IC manufactured by Harris Semiconductor (now part of Intersil). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Harris Semiconductor  
- **Part Number:** ICL7660CBA-T  
- **Type:** Voltage Converter (Charge Pump)  
- **Input Voltage Range:** 1.5V to 10V  
- **Output Voltage:** Negative or Doubled Input Voltage (Configurable)  
- **Output Current Capability:** Up to 20mA  
- **Switching Frequency:** ~10kHz (internal oscillator)  
- **Package:** 8-Pin SOIC (CBA-T denotes tape and reel packaging)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
The ICL7660CBA-T is a monolithic CMOS voltage converter designed to generate negative or doubled supply voltages from a single positive input. It operates as a charge pump, eliminating the need for inductors. The device is commonly used in applications requiring low-power voltage inversion or doubling.  

### **Features:**  
- **Wide Input Voltage Range (1.5V to 10V)**  
- **Low Power Consumption (CMOS Technology)**  
- **No External Inductors Required**  
- **Simple External Capacitor Configuration**  
- **Can Double Input Voltage (Voltage Doubler Mode)**  
- **Internal Oscillator (No External Timing Components Needed)**  
- **Minimal External Components (Only 2 Capacitors Required for Basic Operation)**  

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

Application Scenarios & Design Considerations

CMOS Voltage Converters

Alternative Part Number

  • LTC1044CS8#PBF --: Pin-compatible CMOS charge-pump voltage converter with the same 8-pin SOIC footprint and similar inverting/doubling function; widely available and a direct functional replacement.
  • MAX660CSA+ --: Monolithic charge-pump voltage converter that can invert or double the input voltage, functionally equivalent to the ICL7660 with comparable current capability and 8-pin SOIC package.
  • TC7660EOA --: Direct functional equivalent of the ICL7660 charge-pump converter in an 8-pin SOIC package, offering the same voltage inversion and multiplication modes.

Description and Introduction

CMOS Voltage Converters The ICL7660CBA-T is a voltage converter IC manufactured by INTERSIL. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** INTERSIL  
- **Type:** Voltage Converter (Charge Pump)  
- **Input Voltage Range:** 1.5V to 10V  
- **Output Voltage:** Negative of input (inverts voltage) or doubled (with external capacitors)  
- **Output Current:** Up to 40mA (depending on configuration)  
- **Switching Frequency:** ~10kHz (adjustable with external capacitor)  
- **Package:** 8-Pin SOIC (CBA-T denotes tape and reel packaging)  
- **Operating Temperature Range:** 0°C to 70°C  

### **Descriptions:**  
- The ICL7660CBA-T is a monolithic CMOS voltage converter designed to generate a negative supply from a positive input.  
- It can also function as a voltage doubler with minimal external components.  
- It is commonly used in applications requiring a simple, low-power negative voltage supply.  

### **Features:**  
- **Low Power Consumption:** CMOS technology ensures minimal power draw.  
- **No Inductors Required:** Uses only external capacitors for operation.  
- **Wide Input Voltage Range:** Supports 1.5V to 10V input.  
- **High Efficiency:** Typically >90% for voltage inversion.  
- **Simple External Circuitry:** Requires only two external capacitors for basic operation.  
- **Pin-Compatible with Industry Standards:** Can replace similar charge pump ICs.
