Maxim Integrated MAX1700EEE Step-Up DC-DC Converter

The MAX1700EEE from Maxim Integrated is a high-efficiency, low-quiescent-current, step-up DC-DC converter designed to provide a compact and reliable power solution for a wide range of applications. This versatile component is particularly suitable for portable devices where extended battery life is crucial, such as mobile phones, PDAs, and other handheld equipment.

Encased in a compact 16-pin QSOP package, the MAX1700EEE boasts an input voltage range of 0.7V to 5.5V, making it ideal for single-cell or multiple-cell battery-powered applications as well as for systems powered by a regulated supply voltage. Its adjustable output voltage, which can be set from 2.5V to 5.5V using external resistors, allows designers to tailor the output to meet the specific needs of their application.

Featuring a high switching frequency of up to 600kHz, the MAX1700EEE enables the use of small, low-profile inductors and capacitors, thus reducing the overall footprint and component cost. The device also includes a built-in synchronous rectifier, which enhances efficiency by reducing power loss during the conversion process. This results in efficiency levels up to 96%, ensuring minimal drain on the battery and longer operating times for the end-user.

The MAX1700EEE incorporates several protection features to ensure the longevity and stability of the end application. These include thermal overload protection, which prevents the device from overheating, and a current limit to protect the circuit from excessive input currents. Additionally, the device has a low-battery detector that signals when the input voltage falls below a predetermined threshold, alerting the system to a potential power failure.

Overall, the MAX1700EEE is a robust and efficient solution for designers looking to maximize the performance of their portable power-driven applications. Its high efficiency, flexible voltage options, and compact size make it an excellent choice for modern electronic devices that demand reliable and long-lasting power sources.
