Description and Introduction

CMOS Monolithic Voltage Converter The MAX660CSA is a charge-pump voltage inverter manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** +1.5V to +5.5V  
- **Output Voltage:** -1.5V to -5.5V (inverts input voltage)  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 10kHz (typical)  
- **Power Efficiency:** Up to 99%  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions:**  
- The MAX660CSA is a monolithic, CMOS charge-pump voltage inverter that converts a positive input voltage to a corresponding negative output voltage.  
- It does not require inductors, making it suitable for space-constrained applications.  
- The device is designed for low-power applications and provides a simple, cost-effective solution for generating negative voltages.  

### **Features:**  
- **No Inductors Required** – Uses only external capacitors for operation.  
- **Low Power Consumption** – Ideal for battery-powered applications.  
- **High Efficiency** – Up to 99% power conversion efficiency.  
- **Simple External Components** – Requires only two flying capacitors.  
- **Wide Input Voltage Range** – Supports operation from 1.5V to 5.5V.  
- **Compact Package** – Available in an 8-pin SOIC for space-saving designs.  

The MAX660CSA is commonly used in applications such as LCD biasing, data acquisition systems, and portable electronics requiring a negative voltage supply.
