Maxim Integrated MAX1720EUT+T Step-Up DC-DC Converter

The MAX1720EUT+T from Maxim Integrated is a high-efficiency, compact, synchronous step-up DC-DC converter designed for small, portable electronic devices. This versatile component is capable of delivering a stable output voltage from a single-cell lithium-ion (Li+) battery or other low-voltage power sources, making it an ideal choice for applications such as handheld medical devices, wireless headsets, and other portable gadgets.

The MAX1720EUT+T operates over a wide input voltage range from 0.7V to 5.5V, which allows it to function with sources that have significant voltage variation. This feature is particularly useful when dealing with batteries that can experience a wide range of charge levels. The device is capable of boosting the input voltage to a fixed output voltage, which can be set by an external resistor divider, thus providing great flexibility to match the needs of various applications.

One of the key advantages of the MAX1720EUT+T is its high efficiency, which is achieved through a combination of low quiescent current and a synchronous rectification topology. This efficiency minimizes heat generation and maximizes battery life, which is critical for portable devices. The device also features a True Shutdown™ mode that disconnects the output from the input when disabled, reducing the shutdown current to as low as 0.1µA, further preserving battery life.

The MAX1720EUT+T comes in a small, 6-pin SOT23 package, making it an excellent choice for space-constrained applications. Additionally, it requires minimal external components, which simplifies the design and reduces the overall solution size. The device also includes built-in safety features such as over-temperature protection and an over-current limiting function, providing reliable operation under various conditions.

Overall, the Maxim Integrated MAX1720EUT+T is a powerful, efficient, and reliable solution for boosting voltage in portable electronic devices. Its small footprint, high efficiency, and ease of use make it an excellent choice for designers looking to optimize their power management solutions.
