Overview

The MAX660CPA+ is a switched-capacitor voltage converter designed to generate a negative voltage from a positive input supply. It operates as a charge pump, offering a compact solution for negative-voltage generation in various applications. With a low external part count, it simplifies circuit design.

Why Choose This Part

This converter offers the advantage of a fixed output type and can be configured for either positive or negative output. With selectable switching frequencies of 10kHz or 80kHz, it provides flexibility in optimizing for efficiency or ripple. Its simple charge pump topology minimizes the need for external components, reducing board space and cost.

Applications

Negative Voltage Generation
Ideal for applications requiring a negative supply rail from a single positive input, such as biasing operational amplifiers or other analog circuits.
Low Power Portable Devices
Its switched-capacitor topology is suitable for portable devices needing a negative voltage without complex inductive boost/buck converters.
Analog Signal Processing
Provides a convenient negative supply for precision analog circuits, sensors, and data acquisition systems.
Battery Powered Systems
Can be used in battery-powered applications where both positive and negative supply rails are necessary for certain components.
