MAX1677EEE Equivalent & Substitute Parts Reference

Part Overview

The MAX1677EEE (Analog Devices Inc./Maxim Integrated, Power Management IC) is a boost switching regulator providing two positive adjustable (or fixed) outputs, suitable for surface mount applications in a 16-SSOP package. The device is currently obsolete, necessitating the selection of alternative models for active designs, repair, or ongoing manufacturing. Alternatives must match all relevant electrical, mechanical, regulatory, and packaging parameters to ensure direct replacement suitability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are select based strictly on the parameters explicitly provided: function (step-up), output configuration (positive), topology (boost), number of outputs (2), output type (adjustable/fixed), identical input/output voltage ranges, output current, switching frequency, synchronous rectifier presence, identical mounting type and mechanical package, identical temperature rating, and alignment on regulatory compliance statements and certifications. Only parts matching these listed parameters are valid substitutes for the MAX1677EEE.

Parameter Comparison

Engineering Selection Recommendations

Selection between MAX1677EEE and MAX1677EEE+ is determined by product status and regulatory compliance. The MAX1677EEE is obsolete and RoHS non-compliant. The MAX1677EEE+ is active, ROHS3 compliant, and retains identical mechanical, electrical, and certification parameters. For RoHS-compliant designs or where ongoing availability is required, MAX1677EEE+ is suitable.

Frequently Asked Questions (FAQ)

Q1: What parameters must match between MAX1677EEE and a substitute?
