Maxim Integrated MAX1672EEE+T Step-Up DC-DC Converter

The MAX1672EEE+T from Maxim Integrated is a high-efficiency, compact, step-up DC-DC converter designed for a variety of applications. This versatile component is an ideal solution for battery-powered devices due to its ability to boost lower voltages to higher levels, necessary for powering electronics that require a voltage greater than what the battery can provide. The MAX1672EEE+T is especially well-suited for portable devices, such as PDAs, digital cameras, and other handheld equipment.

This step-up converter operates over a wide input voltage range from 2.7V to 11V, making it compatible with multiple battery chemistries and configurations. It can deliver an adjustable output voltage up to 28V, which is set using two external resistors. This feature allows for a high degree of flexibility, enabling the MAX1672EEE+T to be used in a wide array of applications where specific output voltages are required.

One of the key features of the MAX1672EEE+T is its high efficiency, which can reach up to 94%. This efficiency is achieved through the use of an integrated synchronous rectifier and a pulse-frequency modulation (PFM) control scheme, which reduces the quiescent current and improves efficiency at light loads. As a result, this step-up converter helps to extend battery life in portable applications.

The device is housed in a 16-pin QSOP package, which is known for its small footprint. This compact form factor is critical for space-constrained applications. Additionally, the MAX1672EEE+T includes a range of protective features such as over-temperature protection and a thermal shutdown mechanism to ensure reliable operation under various conditions.

With its combination of high efficiency, adjustable output voltage, and compact size, the Maxim Integrated MAX1672EEE+T step-up DC-DC converter is an excellent choice for designers looking to optimize power management in their next-generation portable devices.
