Maxim Integrated MAX641AESA+T Step-Up DC-DC Converter

The MAX641AESA+T from Maxim Integrated is a high-efficiency, step-up DC-DC converter designed to provide a reliable power solution for battery-powered devices. This component is particularly well-suited for applications where extended battery life is crucial, such as portable consumer electronics, wireless communication devices, and handheld medical equipment.

This converter operates over a wide input voltage range from 2V to 16.5V, making it versatile for various power sources, including single-cell or multiple-cell batteries. The MAX641AESA+T is capable of delivering an adjustable output voltage up to 22V or a fixed output voltage, depending on the needs of the application. Its high switching frequency of 100kHz allows the use of small, low-cost inductors and capacitors, reducing the overall footprint and cost of the power supply design.

Featuring a quiescent current of just 210µA, the MAX641AESA+T ensures minimal power drain when in operation, contributing to the overall energy efficiency of the end product. Additionally, it includes a shutdown mode that reduces the supply current to only 15µA, further conserving battery life when the device is not in active use.

The MAX641AESA+T comes in a compact 8-pin SOIC package, making it easy to integrate into space-constrained designs. It also includes built-in safety features such as thermal overload protection and current limit, which provide added reliability and protection for the converter and the system it powers.

Maxim Integrated's commitment to quality ensures that the MAX641AESA+T meets the strictest performance standards. Its robust design and efficient operation make it an excellent choice for designers looking to enhance the power management capabilities of their next-generation electronic devices.
