MAX772ESA Equivalent & Substitute Parts

Part Overview

The MAX772ESA is a Boost Regulator Positive Output Step-Up DC-DC Controller IC manufactured by Analog Devices Inc./Maxim Integrated in 8-SOIC surface mount packaging. This component functions as a transistor driver for step-up (boost) topology power management applications with a single positive output phase. The MAX772ESA is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX772ESA is determined by strict equivalence across the following critical parameters: boost regulator topology, positive output configuration, single output phase, transistor driver output type, 3V to 16.5V supply voltage range, 300kHz switching frequency, 8-SOIC package format, surface mount mounting type, enable control feature, and -40°C to 85°C operating temperature range.

The substitute parts identified maintain identical electrical and mechanical specifications across all these parameters. Substitutes are grouped into two categories: direct manufacturer part number variants and parametric equivalents from the same manufacturer series.

Engineering Selection Recommendations

For applications currently using the MAX772ESA, the MAX771ESA+ is the preferred substitute. This part maintains complete electrical and mechanical equivalence while offering Active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment for new production.

The MAX772ESA+ and MAX770ESA+ are direct manufacturer alternatives with identical electrical specifications and ROHS3 compliance. However, both carry Not For New Designs status, limiting their suitability for new development. These parts are appropriate only for legacy system maintenance or replacement scenarios where existing designs must be preserved.

All substitute parts share identical package geometry (8-SOIC), mounting type (surface mount), and electrical operating parameters, enabling direct pin-compatible replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can MAX772ESA+ be used as a direct replacement for MAX772ESA?

A: Yes. The MAX772ESA+ is a direct manufacturer variant with identical electrical specifications, package format, and pin configuration. The primary difference is improved RoHS compliance (ROHS3 vs. non-compliant) and Not For New Designs status.

Q: What is the difference between MAX770ESA+ and MAX771ESA+?

A: Both parts are parametric equivalents with identical electrical and mechanical specifications. The key distinction is product status: MAX770ESA+ is Not For New Designs, while MAX771ESA+ is Active. For new applications, MAX771ESA+ is the recommended choice.

Q: Are all substitute parts pin-compatible with MAX772ESA?

A: Yes. All substitute parts use the 8-SOIC package format with identical pinout and electrical characteristics, enabling direct replacement without PCB modification.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance status affects regulatory acceptance and long-term supply chain viability. ROHS3-compliant parts (MAX772ESA+, MAX770ESA+, MAX771ESA+) meet current environmental standards, while the original MAX772ESA does not.

Q: Which substitute should be selected for new designs?

A: MAX771ESA+ is the recommended choice for new designs, as it maintains Active product status and ROHS3 compliance, ensuring sustained manufacturer support and regulatory alignment.

Q: Can these parts be used interchangeably in existing production?

A: Yes, all substitute parts maintain identical electrical performance and package compatibility. Existing designs can transition to any substitute without circuit redesign, though MAX771ESA+ is preferred for long-term production continuity.
