The MAX1722EZK-T from Maxim Integrated is a high-efficiency, compact, step-up DC-DC converter that is ideal for portable applications. This device is designed to provide a reliable voltage boost solution for batteries and other low-voltage sources. It is part of the EasyDrive™ series, which is known for its simple design and ease of use.

Operating from an input voltage as low as 0.7V, the MAX1722EZK-T can start up with a minimum input of just 0.88V and remain operational down to 0.7V. This makes it particularly suitable for single-cell, multi-cell alkaline, NiMH, NiCd, or single-cell Li-ion batteries. The output voltage is adjustable from 2V to 5.5V, allowing for a wide range of applications and compatibility with various microcontrollers, sensors, and other electronic components.

The MAX1722EZK-T comes in a tiny 5-pin SOT23 package, making it an excellent choice for space-constrained applications. Despite its small size, it offers a high switching frequency of up to 500kHz, which enables the use of small, low-cost inductors and capacitors, further minimizing the overall solution size.

With an impressive efficiency of up to 95%, this converter helps to maximize battery life. It also features a "True Shutdown™" mode, which disconnects the output from the input when disabled, ensuring minimal power consumption when not in active use. Additionally, the device incorporates a low-battery detector that signals when the input voltage falls below a user-adjustable threshold, providing an early warning for low power conditions.

The MAX1722EZK-T is equipped with several protective features, including over-temperature protection and current limit, enhancing the safety and reliability of the end application. These features, combined with its high efficiency and adjustable output, make the MAX1722EZK-T a versatile choice for designers looking to add a boost converter to their power management solutions.

Overall, Maxim Integrated's MAX1722EZK-T is a powerful, versatile, and user-friendly step-up converter that delivers performance and ease of integration, making it an excellent choice for a wide array of portable and battery-powered applications.
