Overview

Description

The TC7660COA is a charge pump voltage converter integrated circuit (IC), designed to efficiently convert a positive input voltage to a negative output voltage. It is commonly used in applications requiring a negative voltage supply from a positive input, such as operational amplifiers, data converters, and other analog circuitries.
Key features of the TC7660COA include low quiescent current, high efficiency, and the ability to operate with input voltages ranging from 1.5V to 10V. The device can deliver output voltages close to the negative of the input voltage and is capable of sourcing moderate current levels, typically in the range of tens of milliamperes.
The TC7660COA is packaged in a compact 8-pin DIP or SOIC configuration, making it easy to integrate into a variety of designs. It requires only two external capacitors to function, which simplifies the overall circuit design. Due to its ease of use, compact size, and reliability, the TC7660COA is popular in battery-powered and portable devices where minimizing power consumption and space is crucial.
