Maxim Integrated MAX1723EZK-T Step-Up DC-DC Converter

The MAX1723EZK-T is a high-efficiency, compact, step-up DC-DC converter designed by Maxim Integrated, a renowned leader in analog and mixed-signal engineering. This component is part of Maxim's extensive range of power management integrated circuits, engineered to provide reliable and efficient power solutions for a variety of applications.

This step-up converter is specifically tailored for portable electronic devices that require a stable voltage supply from low-voltage sources, such as single-cell or dual-cell alkaline, NiCd, NiMH, and single-cell Li-ion batteries. The MAX1723EZK-T operates from an input voltage as low as 0.7V, making it an excellent choice for applications where the input source has a limited charge, such as in battery-powered devices.

The device features a fixed 5V or adjustable output voltage, which allows designers to customize the output according to the needs of their specific application. Its high switching frequency of up to 600kHz enables the use of tiny, low-cost capacitors and inductors, which is a significant advantage for space-constrained designs. Additionally, the MAX1723EZK-T boasts a quiescent current of only 5µA, contributing to extended battery life in portable devices.

One of the key benefits of the MAX1723EZK-T is its True Shutdown™ mode, which completely disconnects the output from the input when it is not enabled, preventing any leakage current from draining the battery. Furthermore, the device incorporates a range of protective features, including over-voltage protection, thermal shutdown, and a current limit to safeguard the circuitry against damage from abnormal operating conditions.

The MAX1723EZK-T is available in a compact 5-pin SOT-23 package, which is ideal for space-sensitive applications. Its small footprint and minimal external component requirements make it a popular choice for designers working on portable electronics, such as handheld medical devices, wireless sensors, and personal entertainment systems.

Overall, the Maxim Integrated MAX1723EZK-T is a versatile and efficient solution for boosting voltage in portable electronics, offering a blend of performance, protection, and miniaturization that is hard to match.
