MAX5064AATC+

Overview

The MAX5064AATC+ is a high-efficiency, synchronous step-down DC/DC converter manufactured by Analog Devices Inc. (Maxim Integrated). It operates with an input voltage range of 2.7V to 18V and delivers up to 3A of output current. The device integrates N-channel power switches and features a fixed switching frequency of 500kHz. Key electrical parameters include a quiescent current of 120µA in active mode and 2.5µA in shutdown mode. It supports adjustable output voltages from 0.8V to 15V with ±1% accuracy. The component is housed in a thermally enhanced 16-lead TSSOP package.

Feature Summary

• Integrates high-side and low-side N-channel power MOSFETs for efficient synchronous rectification
• Features constant-frequency peak current-mode control architecture
• Includes programmable soft-start and tracking capabilities for system sequencing
• Provides comprehensive protection against over-current, over-temperature, and short-circuit conditions

Applications

• Portable instrumentation and test equipment
• Industrial process control systems
• Battery-powered mobile devices
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix 'AATC+' against the manufacturer's official datasheet to confirm pinout compatibility and thermal performance specifications. Ensure that the ordering information matches the exact package type and temperature grade required for your design. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and supply chain integrity before procurement.

Selection Notes

Select this component when a compact solution is required for converting higher input voltages down to lower logic or analog supply rails. The integrated power switches reduce external component count compared to non-synchronous alternatives. Consider the 500kHz switching frequency as a balance between efficiency and passive component size. Verify that the load current requirements do not exceed the 3A continuous limit under worst-case thermal conditions.

Part Context

This part belongs to the MAX5064 family of synchronous buck converters designed for medium-power applications. It is distinct from the MAX5066 series which offers different current ratings and packaging options. The device is part of Maxim Integrated's portfolio of power management solutions now managed by Analog Devices following their acquisition.

Replacement Considerations

Consult the manufacturer's cross-reference tool for verified substitutes. Potential equivalents may include other 3A synchronous buck converters from the same product family or competitors offering similar input ranges and current capabilities.
