Maxim Integrated MAX758AEWE+ Step-Up DC-DC Converter

The MAX758AEWE+ from Maxim Integrated is a high-efficiency, compact, step-up DC-DC converter that is designed to deliver a stable and reliable voltage supply. This component is particularly suitable for portable devices where power efficiency and space are critical considerations. The MAX758AEWE+ is capable of stepping up low voltages from batteries to the levels required by the electronic circuits, making it ideal for battery-powered applications.

This voltage regulator features an adjustable output that can be set from 2.7V to 5.5V with the use of external resistors, providing design flexibility for various applications. The input voltage range is from 0.7V to 5.5V, allowing the device to operate from a single-cell lithium-ion battery or multiple battery cells in series.

The MAX758AEWE+ employs a pulse-frequency modulation (PFM) control scheme to achieve high efficiencies over a wide range of load conditions. This feature helps in prolonging battery life, which is crucial for portable devices. With its quiescent current of just 110µA, the device ensures minimal power loss during idle periods.

For protection and durability, the MAX758AEWE+ includes features such as thermal shutdown, which prevents damage from overheating, and a current limit to protect the device and the load from excessive current draw. Additionally, it has an under-voltage lockout (UVLO) that ensures the converter operates only when the input voltage is within a safe range.

The MAX758AEWE+ comes in a 16-pin SOIC-W package, which is optimized for space-sensitive applications. Its surface-mount design allows for streamlined integration into PCBs, making it a versatile choice for designers looking to incorporate a reliable power solution into their projects.

Whether you are developing handheld medical devices, portable media players, or any other battery-operated electronics, the Maxim Integrated MAX758AEWE+ step-up DC-DC converter offers the performance and features necessary to meet your power management requirements.
