MAX1760EUB+T - High-Efficiency, Low-IQ, Step-Up DC-DC Converter

The MAX1760EUB+T from Maxim Integrated is a versatile and highly efficient step-up DC-DC converter designed to provide a compact and reliable power solution for portable electronic devices. Its small size and high-efficiency operation make it ideal for battery-powered applications such as handheld computers, medical instruments, wireless headsets, and other portable gadgets where extended battery life is crucial.

This advanced power management IC is capable of generating output voltages up to 5.5V from an input voltage range of 0.7V to 5.5V, making it particularly suited for products that operate on a single-cell lithium-ion (Li+) battery or multiple alkaline/NiMH cells. The MAX1760EUB+T is capable of delivering up to 500mA of output current (depending on input/output voltage differential), ensuring a stable power supply for a wide range of applications.

The device features a quiescent current (IQ) of just 28µA, which significantly reduces power consumption during idle periods, thus preserving battery life. Additionally, the MAX1760EUB+T includes a low-power shutdown mode that further minimizes battery drain by reducing the supply current to less than 1µA when the device is not in active use.

Another highlight of the MAX1760EUB+T is its high switching frequency of up to 500kHz, which allows for the use of small, low-cost inductors and ceramic capacitors. This not only reduces the overall footprint of the power supply design but also simplifies the circuit layout and reduces the bill of materials.

For protection and safety, the MAX1760EUB+T incorporates several features such as overvoltage protection, thermal shutdown, and under-voltage lockout. These safeguards ensure the longevity of the device and the safety of the end product under varying operating conditions.

The MAX1760EUB+T is available in a tiny, 10-pin µMAX package, making it an excellent choice for space-constrained applications. Its compact form factor, combined with its robust feature set, makes it a go-to solution for designers looking to maximize the performance and efficiency of their power management systems.

Overall, the MAX1760EUB+T from Maxim Integrated exemplifies a state-of-the-art step-up converter that offers a balance of efficiency, size, and performance, tailored for the demanding requirements of modern portable electronics.
