Maxim Integrated Product Overview: MAX1688ESA

The MAX1688ESA from Maxim Integrated is a versatile, high-efficiency, step-up DC-DC converter designed to meet the power requirements of various applications. This compact and efficient power solution is ideal for portable electronic devices where efficient power conversion and space constraints are of paramount importance.

Encased in an 8-pin SO package, the MAX1688ESA is engineered to provide a high level of performance in a small form factor. It operates from a 2.7V to 5.5V input voltage range, making it suitable for single-cell, two-cell, or three-cell battery-powered applications, as well as for devices powered by a regulated 3.3V or 5V supply.

Key Features

• Adjustable Output: The device offers an adjustable output voltage up to 28V, allowing for a wide range of applications that require different voltage levels.
• High Efficiency: With its high efficiency of up to 87%, the MAX1688ESA ensures minimal power loss during conversion, thereby extending battery life in portable devices.
• Low Quiescent Current: It features a low quiescent current of just 110µA, which is particularly beneficial for battery-powered applications where conserving power is critical.
• Integrated MOSFET: The inclusion of an internal N-channel MOSFET switch eliminates the need for an external power switch, simplifying design and reducing external component count.
• Frequency Operation: A 1.2MHz fixed-frequency PWM operation reduces the size of external components and avoids frequency-sensitive noise in the audio band.
