MAX1635CAI

Overview

The MAX1635CAI is a switching controller designed for multi-output, low-noise power supply applications in notebook computers. It features two outputs with adjustable voltage ranges from 2.5 V to 5.5 V and supports up to 10 A output current. The device operates within a temperature range of -40°C to +85°C and is housed in an SSOP-28 package.

Feature Summary

• Multi-output switching controller architecture
• Low-noise power supply design
• Optimized for notebook computer systems

Applications

• Notebook computer power supplies
• Multi-output logic supply generation
• Battery-powered system voltage regulation

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to discontinued status. Confirm RoHS compliance and package integrity upon receipt. Cross-reference datasheet revisions to ensure compatibility with existing designs. Check for obsolescence notices and lifecycle management updates from Analog Devices.

Selection Notes

Evaluate thermal performance and efficiency requirements against the specified 10 A output capability. Ensure input voltage ranges align with system battery or adapter specifications. Consider EMI constraints given the low-noise design focus. Verify footprint compatibility with SSOP-28 mounting requirements.

Part Context

Part of the MAX1635 series by Maxim Integrated, now under Analog Devices. Designed as a buck-topology step-down switch-mode controller for generating logic-supply voltages in portable electronics. Replaced by newer PMIC solutions but remains documented for legacy system maintenance.

Replacement Considerations

No officially confirmed substitute part numbers are publicly documented for direct replacement. Consult Analog Devices application notes for modern equivalents in the MAX17xxx or MAX20xxx series for updated functionality.
