Maxim Integrated MAX771ESA+ Boost Converter

The Maxim Integrated MAX771ESA+ is a high-efficiency, voltage-mode, step-up DC-DC converter that is designed to deliver a stable and precise output voltage from a lower voltage input. This component is ideal for battery-powered applications where extending the battery life is crucial, as well as for powering devices that require a higher voltage supply than what the battery can offer.

The MAX771ESA+ operates over a wide input voltage range from 2V to 16.5V, making it versatile for various power sources including single-cell to multi-cell batteries, or even regulated power supplies. It can provide an adjustable output voltage up to 28V, which can be set with external resistors. This flexibility allows the MAX771ESA+ to be used in a broad range of applications from portable electronics to industrial systems.

One of the key features of the MAX771ESA+ is its high efficiency, which can go up to 94%. This is achieved through the use of an internal 0.2 Ohm N-channel MOSFET switch. The device also includes a frequency compensation circuit which simplifies the design and reduces external component count. Furthermore, it offers a low quiescent current of only 110µA, which helps in minimizing the standby power consumption.

The MAX771ESA+ is equipped with several protective features that ensure the safety and reliability of the system it is integrated into. These include thermal shutdown, frequency foldback, and a current limit. Additionally, it comes in a compact 8-pin SOIC package, which is suitable for space-constrained applications.

Whether you're developing a handheld device, a portable medical instrument, or any other application that requires a compact and efficient power boost solution, the MAX771ESA+ from Maxim Integrated is a solid choice that combines performance with ease of use.

For designers and engineers looking for a reliable voltage boost solution, the Maxim Integrated MAX771ESA+ offers the perfect balance of efficiency, versatility, and protection, ensuring a high-quality power supply for your application.
