MAX1717EEG-TG068

Overview

The MAX1717EEG-TG068 is a dynamically adjustable, synchronous step-down DC-DC converter controller IC designed for notebook computer power systems. It features a single output configuration to ensure efficient power regulation. The device operates within a temperature range of -40°C to +85°C and is housed in a 24-pin SSOP package with a width of 3.90mm. It functions as a dedicated regulator for stable power rails.

Feature Summary

• Dynamically adjustable synchronous voltage regulation
• Optimized for notebook computer power system control
• Single-output step-down DC-DC conversion

Applications

• Notebook computer power management
• Stable DC-DC power rail generation
• Synchronous buck converter control circuits

Procurement Notes

Verify the component status carefully, as source data indicates this part may be obsolete. Confirm the manufacturer designation between Analog Devices Inc. and Maxim Integrated, as both are listed. Ensure the specific suffix TG068 matches your design requirements, as it denotes a specific tape-and-reel variant or packaging code distinct from standard versions.

Selection Notes

Select this component only if designing for legacy notebook architectures requiring a synchronous buck controller. The 24-SSOP package requires appropriate PCB footprint planning. Consider that the operating temperature range covers industrial standards (-40°C to +85°C). Verify compatibility with external MOSFETs for the synchronous rectification stage, as this is a controller rather than an integrated switch.

Part Context

This part belongs to the MAX1717 family of power management ICs from Maxim Integrated, now part of Analog Devices. These controllers were widely used in portable computing applications before transitioning to newer generations. The EG suffix typically indicates the commercial/industrial temperature grade and package type.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Due to the obsolete status indicated in some records, direct pin-to-pin replacements should be verified against current Analog Devices portfolios for modern notebook power designs.
