Maxim Integrated MAX861ESA+T Charge Pump Voltage Converter

The MAX861ESA+T is a compact, high-efficiency charge pump voltage converter designed by Maxim Integrated, a company renowned for its innovative and reliable power management solutions. This voltage converter is an ideal choice for applications that require a regulated voltage source from a higher or lower voltage supply, and it is particularly well-suited for small, battery-powered devices due to its low power consumption and small footprint.

Featuring a wide input voltage range of 2.0V to 5.5V, the MAX861ESA+T can deliver an adjustable and regulated output voltage, which makes it highly versatile for various applications. Its output can be set to fixed voltages of 2.7V, 3.0V, 3.3V, 5.0V, or adjusted up to 5.5V using external resistors, providing designers with flexibility in their circuit designs.

This charge pump converter operates using a switched-capacitor voltage doubling technology, which allows it to provide high efficiency without the need for inductors, thereby reducing noise and simplifying the layout. The device features a high switching frequency of 125kHz, enabling the use of small, cost-effective capacitors while still maintaining low output ripple and noise.

The MAX861ESA+T also includes a number of built-in protection features to ensure reliable operation. These include thermal overload protection, which prevents the device from overheating, and short-circuit protection, which safeguards the converter and the downstream circuitry from damage due to output short conditions.

Its 8-pin SOIC package is designed for surface mounting, making it easy to integrate into a variety of circuit boards. The MAX861ESA+T is also available in tape and reel packaging, denoted by the '+T' suffix, which facilitates automated assembly processes, making it an excellent choice for high-volume production.

Whether you're designing portable consumer electronics, handheld devices, or any other application that requires a compact and efficient voltage conversion solution, the MAX861ESA+T from Maxim Integrated offers the performance and reliability you need in a small, easy-to-use package.
