Description

The MAX829EUK+T is a DC-DC boost converter designed by Maxim Integrated. It is primarily used to increase low input voltages to higher output voltages, making it suitable for battery-powered devices and systems requiring efficient power management. The device operates with a fixed output voltage and features a low quiescent current, which helps to extend battery life. It is packaged in a compact SOT-23 configuration, making it ideal for space-constrained applications.
The MAX829EUK+T is known for its high efficiency, typically achieved through a low RDS(ON) MOSFET integrated within the device. It supports applications such as portable consumer electronics, handheld devices, and other applications requiring a compact, efficient boost in voltage. The device also includes various protective features, such as overcurrent protection, ensuring reliability and safety during operation. It is essential to consult the datasheet for specific electrical characteristics, circuit design recommendations, and application guidelines to ensure the device meets the requirements of a given project.

Features

The MAX829EUK+T is a step-up DC-DC converter designed by Maxim Integrated. It features high efficiency, typically around 90%, and is capable of delivering output voltages up to 28V from an input range of 0.8V to 5.5V. The device is optimized for battery-powered applications due to its low quiescent current of 12µA, which helps to extend battery life.
It offers a fixed frequency of 170kHz, easing the design of circuits by allowing for smaller external components. The MAX829EUK+T also has a shutdown mode, reducing current draw to approximately 1µA when not in use. It includes protection features such as current limiting and thermal shutdown, which enhance reliability by preventing damage under fault conditions.
The part is housed in a compact SOT-23-5 package, which is ideal for space-constrained applications. These features make the MAX829EUK+T suitable for portable electronics, handheld devices, and other scenarios where efficient voltage boosting is needed without significant power loss.

Package

The MAX829EUK+T is packaged in a 5-pin SOT-23 package.

Pinout

The MAX829EUK+T is a 5-pin SOT23 package device. It is a voltage inverter, which means it is designed to convert a positive input voltage to a negative output voltage. Specifically, the function of the MAX829EUK+T is to generate a negative voltage output from a positive input supply, making it useful in applications that require dual power supply rails where only a positive voltage is available initially.

Manufacturer

The MAX829EUK+T is manufactured by Maxim Integrated. Maxim Integrated is a company that designs and manufactures analog and mixed-signal integrated circuits. It serves a wide range of markets, including industrial, communications, consumer, and automotive sectors. In 2021, Maxim Integrated was acquired by Analog Devices, Inc., which is a prominent player in the semiconductor industry, focusing on high-performance analog, mixed-signal, and digital signal processing integrated circuits.

Application

The MAX829EUK+T is a high-efficiency step-up DC-DC converter used in various applications. It is ideal for powering low-voltage devices from a single battery cell due to its low supply current and the ability to boost output voltage. Common application areas include portable electronics, battery-powered devices, handheld instruments, and wireless sensors. Its compact size makes it suitable for space-constrained designs.
