Maxim Integrated MAX860EUA+ Charge Pump Voltage Converter

The Maxim Integrated MAX860EUA+ is a highly efficient, CMOS charge-pump voltage converter that delivers a regulated output. This device is designed to provide a simple and compact power solution for applications that require a positive-to-negative voltage conversion. It is well-suited for battery-powered devices, as well as for portable consumer electronics, where space is at a premium and energy efficiency is crucial.

The MAX860EUA+ operates over a wide input voltage range of 1.5V to 5.5V, making it versatile for various power sources, including single-cell batteries. The output voltage is inverted from the input voltage, providing a regulated -1.5V to -5.5V output, with an output current capability of up to 200mA. This makes it an excellent choice for applications that require a negative supply voltage generated from a positive input.

One of the key features of the MAX860EUA+ is its high power efficiency, which is achieved through a switched-capacitor, voltage-inversion technology. This technology allows the device to operate with a quiescent current of only 120µA, thereby conserving power and extending battery life in portable applications. Additionally, the device includes an oscillator, a low-battery detector, and current limit and thermal shutdown protection features to ensure reliable operation under various conditions.

The MAX860EUA+ is available in a compact 8-pin µMAX package, which is ideal for space-constrained designs. The small footprint of the package does not compromise its performance or functionality, making it a practical choice for designers looking to minimize board space without sacrificing quality.

Overall, the Maxim Integrated MAX860EUA+ is a robust and reliable solution for generating a negative voltage rail in a wide array of electronic devices. Its ease of use, combined with its high efficiency and low-power operation, makes it an excellent choice for engineers and designers looking to optimize their power supply designs.
