Maxim Integrated's MAX9660ETA+T: A High-Efficiency Step-Up Converter

The MAX9660ETA+T from Maxim Integrated is a versatile and efficient DC-DC step-up converter designed to meet the needs of compact, high-performance electronic systems. This integrated circuit is particularly suited for battery-powered applications where maximizing battery life is crucial. The device operates from a 0.7V to 5.5V input voltage range, making it ideal for single-cell or multi-cell battery configurations, as well as for regulated 5V systems.

The MAX9660ETA+T offers a high switching frequency of 1.2MHz, which allows for the use of small, low-cost inductors and capacitors, resulting in a compact power supply design. This high frequency also enables fast transient response, keeping the output voltage stable under dynamic load conditions. The device is capable of providing an adjustable output voltage up to 5.5V, giving designers the flexibility to tailor the power supply to the specific needs of their application.

Featuring a high efficiency of up to 96%, the MAX9660ETA+T minimizes power loss, thus prolonging battery life in portable devices. Additionally, the device includes a True Shutdown™ feature that disconnects the output from the input when disabled, reducing the quiescent current to virtually zero and further conserving battery power when the device is not in use.

With built-in safety features such as over-temperature protection and over-current protection, the MAX9660ETA+T ensures reliable operation under various conditions. The device is available in a small, 8-pin TDFN package with an exposed pad, which aids in heat dissipation and allows for operation over a wide temperature range.

Maxim Integrated's MAX9660ETA+T is an excellent choice for designers looking to create efficient, space-saving power supplies for applications such as handheld devices, portable media players, wireless sensors, and other power-sensitive electronics. Its combination of high efficiency, flexible voltage options, compact design, and robust protection features make it a highly capable component for modern electronic designs.
