Description and Introduction

CMOS Monolithic Voltage Converter The MAX660CPA is a monolithic CMOS charge-pump voltage inverter manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** +1.5V to +5.5V  
- **Output Voltage:** -1.5V to -5.5V (inverts input voltage)  
- **Output Current:** Up to 100mA  
- **Conversion Efficiency:** Up to 99%  
- **Operating Frequency:** ~10kHz (internal oscillator)  
- **Low Supply Current:** 0.5mA (typical)  
- **Package:** 8-pin PDIP (Plastic Dual In-line Package)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
The MAX660CPA is a voltage inverter that generates a negative output voltage from a positive input without using inductors. It uses a charge-pump architecture, making it suitable for applications requiring small, efficient voltage inversion.  

### **Features:**  
- No external inductors required  
- Simple two external capacitor design  
- Low power consumption  
- High efficiency  
- Space-saving 8-pin DIP package  
- Compatible with standard CMOS logic  

This device is commonly used in portable electronics, data acquisition systems, and other applications requiring a negative supply rail.

Application Scenarios & Design Considerations

CMOS Monolithic Voltage Converter

Alternative Part Number

  • ICL7660CPA --: Pin-compatible CMOS voltage converter in the same 8-pin DIP package with equivalent charge-pump function, widely used as a direct MAX660 substitute.
  • LT1054CN8 --: Switched-capacitor voltage converter with higher output current and similar DIP-8 pinout, suitable replacement for MAX660 charge-pump applications.
  • TC7660CPA --: Low-cost CMOS charge-pump voltage converter in DIP-8, functionally equivalent to MAX660 for voltage inversion and doubling circuits.
