Maxim Integrated MAX1663EUB - Product Overview

The MAX1663EUB from Maxim Integrated is a highly efficient, low-voltage, step-down DC-DC converter designed to deliver a seamless power management solution for battery-powered and low-voltage applications. Its compact form factor, encapsulated in a 10-pin μMAX package, makes it an ideal choice for space-constrained devices.

Key Features

• Wide Input Voltage Range: The device operates from a 2.6V to 3.6V input voltage range, making it suitable for single-cell lithium-ion (Li+) batteries or three-cell NiMH/NiCd batteries.
• High Efficiency: With an efficiency of up to 96%, the MAX1663EUB ensures minimal power loss during conversion, extending battery life for portable devices.
• Adjustable Output Voltage: Users can set the output voltage from 1.25V to V<sub>IN with an external resistor divider, providing flexibility for various design requirements.
• Low Quiescent Current: The quiescent current of only 110µA (typical) during operation and 0.1µA in shutdown mode contributes to the conservation of battery life in portable applications.
• Integrated Features: The device includes an internal synchronous rectifier, oscillator, feedback and control logic, and compensation components, which reduce the number of external components required.

Applications

The MAX1663EUB is particularly well-suited for a variety of low-voltage and battery-powered applications, such as:

• Handheld Computers and PDAs
• Cellular Phones
• Wireless and DSL Modems
• Portable Media Players
• GPS Receivers

Design and Integration

Integrating the MAX1663EUB into a design is straightforward thanks to its minimal external component requirement. Designers can take advantage of its small footprint and high integration to create compact, efficient power supply circuits. Additionally, the device's fixed 500kHz (typical) switching frequency allows for the use of small, low-cost inductors and capacitors, further simplifying design and reducing overall system cost.

With its balance of efficiency, flexibility, and ease of use, the MAX1663EUB from Maxim Integrated stands as a robust solution for modern low-power electronics, ensuring reliable power management in a miniature package.
