Maxim Integrated MAX1791EUB+T Step-Up DC-DC Converter

The Maxim Integrated MAX1791EUB+T is a highly efficient, compact, and robust step-up DC-DC converter designed to provide a flexible power management solution for a variety of applications. This versatile component is ideal for portable devices, as it is capable of stepping up low input voltages to a higher, regulated output voltage, ensuring stable operation even when battery levels are low.

With an input voltage range of 0.7V to 5.5V, the MAX1791EUB+T can operate from a single cell AAA or AA battery, or even multiple battery cells, making it a perfect choice for handheld and battery-powered equipment. The device can output voltages up to 5.5V, which can be set by an external resistor divider, providing design flexibility to match the specific needs of the application.

The MAX1791EUB+T operates at a switching frequency of 1.2MHz, which allows for the use of small, low-cost inductors and capacitors, thus reducing the overall solution footprint and bill of materials. Additionally, its high frequency enables fast transient response, an important feature for applications with dynamic load requirements.

Featuring a quiescent current of only 30µA, the MAX1791EUB+T is optimized for low-power consumption, making it an energy-efficient choice that extends the battery life of portable devices. In shutdown mode, the current drops to a mere 0.1µA, further conserving power when the device is not in active use.

The MAX1791EUB+T incorporates several protection features, including over-temperature protection and a current limit function, safeguarding the device and the application against adverse conditions. It is available in a small, 10-pin µMAX package, which is not only space-saving but also offers excellent thermal performance.

Maxim Integrated's commitment to quality and reliability is evident in the MAX1791EUB+T, making it a trusted choice for designers looking to create efficient, high-performance power management systems in their next-generation electronic products.
