MAX20458ATID/VY+

Overview

The MAX20458ATID/VY+ is a synchronous boost controller from Analog Devices. It supports an input voltage range of 2.05 V to 36 V and operates at a switching frequency of 400 kHz. The device integrates a 4 A synchronous switch for efficient power conversion. It functions within a minimum operating temperature of -40°C.

Feature Summary

• Integrates a high-current synchronous switch for step-up topology
• Supports wide input voltage ranges up to 36 V
• Operates with fixed switching frequency for stable regulation

Applications

• Industrial power systems requiring 36 V input compatibility
• Battery-powered equipment needing voltage boosting
• Distributed power architectures in automotive or telecom sectors

Procurement Notes

Verify the specific suffix ID against official datasheets to confirm package type and thermal characteristics. Confirm RoHS compliance status directly with the manufacturer documentation before integration into regulated environments.

Selection Notes

Select this component when a 36 V input capability and integrated synchronous rectification are required. Ensure the application load current remains within the 4 A switch limit. Verify that the 400 kHz frequency aligns with EMI constraints and inductor selection requirements.

Part Context

This part belongs to the Maxim Integrated PMIC portfolio, designed for robust power management in industrial and mobile applications. It complements other buck and boost regulators by providing high-density step-up solutions with integrated switching elements.

Replacement Considerations

Check for MAX20458ATIF/VY+ variants which may differ in pinout or thermal performance. Cross-reference with LT8060x series for alternative boost controllers if different switching frequencies are needed.
