MAX662AMSA/PR

Overview

The MAX662AMSA/PR is a DC-DC switching voltage regulator manufactured by Analog Devices Inc./Maxim Integrated. It operates as a boost converter, accepting an input voltage range of 4.5V to 5.5V and providing a fixed 12V output. The device delivers up to 30mA of output current with a typical quiescent current of 185µA. It functions within a temperature range of 0°C to +70°C and utilizes a SOIC-8 surface-mount package.

Feature Summary

• Boost topology for stepping up standard 5V supplies to higher voltages
• Fixed 12V output configuration suitable for specific programming applications
• Low quiescent current consumption for power efficiency
• Integrated shutdown capability for system power management

Applications

• Flash memory programming supply generation
• Battery-powered systems requiring voltage step-up
• Portable electronic devices with limited power budgets

Procurement Notes

Verify the exact suffix designation (e.g., PR vs. PR+) against official manufacturer documentation, as suffixes often indicate packaging variations or environmental compliance status rather than functional differences. Confirm availability status directly with authorized distributors, as this part may be subject to obsolescence or limited stock constraints. Ensure the selected variant matches the required thermal and electrical specifications for your specific application environment.

Selection Notes

Select this component when a fixed 12V output is required from a nominal 5V source with minimal external component count. Consider the 30mA current limit and 185µA quiescent current when designing for battery life. Verify that the SOIC-8 package fits the PCB layout constraints. Compare against other MAX662 variants if different output voltages or packaging options are needed.

Part Context

The MAX662 series comprises high-efficiency, step-up DC-DC converters designed for portable applications. The MAX662AMSA/PR specifically provides a fixed 12V output, distinguishing it from adjustable or other fixed-voltage variants in the family. It is part of Maxim Integrated's portfolio of power management solutions aimed at extending battery life in mobile devices.

Replacement Considerations

Check for MAX662 variants with different output voltages or packages. Consult Analog Devices for direct replacements if the fixed 12V output or specific current ratings do not meet new design requirements.
