MAX772ESA-T Equivalent & Substitute Parts

Part Overview

The MAX772ESA-T 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 device operates from a 3V to 16.5V supply and switches at 300kHz with enable control features.

The MAX772ESA-T is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production or maintenance requirements for systems utilizing this controller.

Substitute Part Grouping Explanation

Substitution eligibility for the MAX772ESA-T is determined by strict equivalence across the following critical parameters:

  • Topology & Function: Boost regulator with positive output step-up DC-DC controller function
  • Output Type: Transistor driver with single positive output phase
  • Electrical Specifications: Supply voltage range 3V ~ 16.5V, switching frequency 300kHz, enable control feature
  • Thermal Range: Operating temperature -40°C ~ 85°C
  • Package Compatibility: 8-SOIC surface mount package (0.154", 3.90mm width)
  • Compliance: ROHS3 compliant, MSL 1 rating

The MAX771ESA+T meets all substitution criteria as a parametric equivalent. Both devices share identical electrical performance specifications, thermal operating range, package form factor, and regulatory compliance status. The primary distinction is product lifecycle status: MAX772ESA-T is obsolete while MAX771ESA+T is active.
