MAX769EEI Low-Voltage, Step-Up DC-DC Converters

The MAX769EEI from Maxim Integrated is a high-efficiency, low-voltage, step-up DC-DC converter designed to provide a solution for portable electronic devices that require a higher voltage from a low-voltage power source. This compact and versatile component is ideal for battery-powered applications, including handheld devices, medical equipment, and wireless communication products.

Featuring a wide input voltage range of 0.7V to 5.5V, the MAX769EEI can start up with a minimum input voltage of 0.7V and then operate down to 0.5V after startup, making it perfect for applications powered by single-cell batteries. Its adjustable output voltage ranges from 2V to 5.5V, providing the flexibility needed to power a variety of circuits and systems.

The device operates in a pulse-frequency modulation (PFM) mode which enhances efficiency at light loads, thus extending battery life. It also has a low quiescent current, further conserving power when the device is in standby mode. Moreover, the MAX769EEI features a 2.5A switch current limit, which is internally set, offering robust power handling capability.

Protection features of the MAX769EEI include thermal shutdown, which prevents damage from overheating, and a current limit to protect the device and the load from excessive current draw. Additionally, the component is offered in an extended industrial temperature range of -40°C to +85°C, ensuring reliable performance across various environmental conditions.

The MAX769EEI comes in a space-saving 16-pin QSOP package, which is suitable for space-constrained applications. It also supports a low-noise operation with its frequency dithering feature, which reduces electromagnetic interference (EMI), making it easier to meet regulatory standards.

With its high efficiency, versatile input and output voltage range, and compact form factor, the MAX769EEI from Maxim Integrated is an excellent choice for designers looking to maximize performance in portable and low-voltage applications.
