MAX767SEAP

Power Supply Controllers, Monitors Overview

The MAX767SEAP is a synchronous step-down power-supply controller designed to convert a fixed 5V input into a tightly regulated 3.3V output. It operates as a high-efficiency DC/DC switch controller in a 20-pin SSOP package with a width of 5.30mm. The device functions as a buck regulator, providing positive output voltage regulation for applications requiring efficient power conversion from standard 5V rails.

Power Supply Controllers, Monitors Feature Summary

• Synchronous buck controller architecture for high efficiency
• Dedicated conversion of fixed 5V supply to regulated 3.3V output
• Surface-mount SSOP-20 packaging

Power Supply Controllers, Monitors Applications

• Systems requiring 5V to 3.3V power conversion
• Embedded electronics using synchronous step-down regulation
• Power supply controllers for digital logic loads

Power Supply Controllers, Monitors Procurement Notes

Verify the manufacturer designation, as sources list both Maxim Integrated and Analog Devices Inc./Maxim Integrated due to corporate acquisition history. Confirm the specific suffix 'SEAP' corresponds to the SSOP-20 package variant. Ensure documentation references the correct revision for electrical characteristics. Cross-reference part numbers like MAX767CAP+ or MAX767SEAP-T if lead times vary, but confirm functional equivalence before procurement.

Power Supply Controllers, Monitors Selection Notes

Select this component when a fixed 5V input rail is available and a regulated 3.3V output is required. The synchronous design offers higher efficiency compared to non-synchronous alternatives. Consider the SSOP-20 package constraints for PCB layout. Evaluate thermal performance requirements based on load current, as the datasheet specifies it as a controller requiring external MOSFETs.

Power Supply Controllers, Monitors Part Context

The MAX767 series comprises synchronous step-down power-supply controllers. Variants include MAX767SEAP, MAX767CAP+, and MAX767TCAP-T, differing primarily in package type and temperature range. The series is characterized by its ability to drive external synchronous rectifiers for efficient voltage stepping.

Power Supply Controllers, Monitors Replacement Considerations

MAX767REAP+ is listed as a comparable part within the same family. Verify pinout compatibility and electrical specifications against the original design requirements before substitution.
