Maxim Integrated MAX1724EZK33-T Step-Up DC-DC Converter

The MAX1724EZK33-T from Maxim Integrated is a high-efficiency, low-quiescent-current step-up DC-DC converter designed to operate from a single-cell lithium-ion (Li+) battery or other power sources ranging from 1.8V to 5.5V. This makes it an ideal choice for portable electronics where extended battery life is crucial, such as handheld devices, medical equipment, and IoT sensors.

With its fixed 3.3V output voltage, the MAX1724EZK33-T provides a stable supply for circuits that require a regulated 3.3V, eliminating the need for additional linear regulators. The device is capable of delivering up to 200mA output current, ensuring sufficient power for a variety of applications.

One of the key features of the MAX1724EZK33-T is its high efficiency, which can reach up to 96%, significantly reducing the power losses during conversion. This is particularly beneficial in battery-powered devices where every milliwatt of power saving can extend the operating time. Additionally, the low quiescent current of only 17µA (typical) further conserves battery life when the device is in standby mode.

The MAX1724EZK33-T comes in a compact 5-pin SOT-23 package, making it suitable for space-constrained applications. It also includes a variety of safety features such as thermal overload protection and a current limit to protect the device and the load from damage due to excessive heat or current draw.

For design flexibility, the MAX1724EZK33-T does not require an external Schottky diode, thanks to its integrated synchronous rectifier. This simplifies the circuit design and reduces the number of external components needed, which can help in reducing the overall solution size and cost.

Overall, the MAX1724EZK33-T is a reliable and efficient solution for designers looking to maximize battery life in their portable or low-power devices. Its ease of use, coupled with Maxim Integrated's reputation for quality, makes it a solid choice for a wide range of power conversion applications.
