MAX5069BAUE Equivalent & Substitute Parts

Part Overview

The MAX5069BAUE is a buck regulator controller IC manufactured by Analog Devices Inc./Maxim Integrated, designed for step-down DC-DC conversion applications. This device functions as a transistor driver for positive, isolation-capable output configurations with a single output phase. The part is classified as obsolete, which necessitates identification of equivalent substitute components for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX5069BAUE is determined by strict equivalence across the following critical parameters:

• Identical base product number (MAX5069 series)
• Matching output type (Transistor Driver)
• Identical function (Step-Down DC-DC Controller)
• Matching output configuration (Positive, Isolation Capable)
• Identical topology (Buck)
• Matching number of outputs and phases (1 output, 1 phase)
• Identical voltage supply range (10.8V ~ 24V)
• Identical switching frequency range (50kHz ~ 2.5MHz)
• Matching duty cycle specification (100% maximum)
• Identical control features (Dead Time Control, Enable, Frequency Control)
• Matching package type (16-TSSOP with Exposed Pad)
• Identical operating temperature range (-40°C ~ 125°C)
• Compliance with RoHS3 and MSL 1 requirements

The substitute part MAX5069BAUE+ meets all these criteria and differs only in product status (Active vs. Obsolete) and packaging format (Tube vs. standard packaging).

Parameter Comparison

Engineering Selection Recommendations

The MAX5069BAUE+ is a direct functional equivalent to the MAX5069BAUE. The primary distinction is product status: the original part is obsolete while the substitute is active. This status difference makes MAX5069BAUE+ the appropriate selection for new designs and ongoing procurement requirements.

Both parts maintain identical electrical and mechanical specifications, including voltage supply range, switching frequency capability, control features, and package configuration. Both comply with ROHS3 requirements and carry MSL 1 rating, indicating no moisture sensitivity constraints during storage and handling.

The packaging format difference (Tube for the substitute) does not affect functional compatibility and is a standard industry variation for active product lines. Selection of MAX5069BAUE+ ensures access to current inventory and ongoing manufacturer support.

Frequently Asked Questions (FAQ)

Q: Can MAX5069BAUE+ be used as a direct replacement for MAX5069BAUE in existing designs?

A: Yes. The MAX5069BAUE+ is functionally identical across all electrical and mechanical parameters. Pin configuration, package dimensions, and performance specifications are equivalent. No design modifications are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: Obsolete status indicates the MAX5069BAUE is no longer manufactured or supported by Analog Devices Inc./Maxim Integrated. The active status of MAX5069BAUE+ ensures continued availability, technical support, and compliance with current manufacturing standards.

Q: Are there any differences in compliance certifications between these parts?

A: Both parts are ROHS3 compliant and carry MSL 1 rating. The MAX5069BAUE+ includes REACH Unaffected status, which is standard for active product lines. Compliance requirements are met by both variants.

Q: Does the Tube packaging format affect circuit board assembly compatibility?

A: No. Tube packaging is a standard distribution format that does not affect the component itself or its performance. The physical part, pin configuration, and electrical characteristics remain identical to standard packaging formats.

Q: What are the critical parameters that define substitution eligibility for this part?

A: Substitution is determined by matching the base product number (MAX5069), output type (Transistor Driver), topology (Buck), output configuration (Positive, Isolation Capable), voltage supply range (10.8V ~ 24V), switching frequency range (50kHz ~ 2.5MHz), control features, package type (16-TSSOP with Exposed Pad), and operating temperature range (-40°C ~ 125°C).
