Maxim Integrated's MAX1673ESA+T Step-Up DC-DC Converter

The MAX1673ESA+T from Maxim Integrated is a high-efficiency, compact, step-up DC-DC converter that is ideal for a wide range of battery-powered applications. This device is designed to boost input voltages as low as 0.7V to a higher, selectable output voltage, making it perfect for devices that run on single-cell batteries or where a higher voltage is required for certain functionalities.

Enclosed in a space-saving 8-pin SO package, the MAX1673ESA+T offers a versatile solution for design engineers looking to maximize power efficiency. Its switching frequency is set at 600kHz, which allows for the use of small, low-cost inductors and capacitors, thus reducing the overall footprint and cost of the power supply design.

One of the standout features of the MAX1673ESA+T is its ability to operate with a quiescent current of only 110µA, which drops to a mere 15µA in shutdown mode. This low power consumption makes it an excellent choice for portable devices where extending battery life is critical. Furthermore, the device includes an internal N-channel MOSFET switch, which can handle up to 1.5A of current, providing ample power for most low-to-medium power applications.

The MAX1673ESA+T also includes a range of built-in protection features to ensure reliable operation. These include thermal overload protection, which prevents damage due to excessive heat, and a current limit function that protects the device and the load from overcurrent conditions. Additionally, the converter has a soft-start feature that minimizes inrush current during startup, thereby reducing stress on the battery and extending its lifespan.

With its high efficiency, small form factor, and robust protection features, the MAX1673ESA+T step-up converter from Maxim Integrated is an excellent choice for designers looking to create compact, power-efficient products without compromising on performance. Whether for handheld medical devices, portable electronics, or any application requiring a reliable power boost, the MAX1673ESA+T is a versatile and dependable power management solution.
