MAX5093AATE+T

Overview

The MAX5093AATE+T is a high-efficiency, synchronous step-down DC-DC converter paired with a low-dropout linear regulator. It operates within an input voltage range of 4.5V to 60V and integrates a 1MHz switching frequency for the buck converter section. The device provides two outputs: one regulated by the synchronous buck topology and another by the integrated LDO. Packaged in a compact 16-TQFN (5x5mm) format with an exposed pad for thermal dissipation, it is designed for space-constrained applications requiring dual power rails from a wide input source.

Feature Summary

• Integrates a high-efficiency synchronous step-down converter with a separate low-dropout linear regulator
• Supports a wide input voltage range suitable for various bus architectures
• Utilizes a fixed 1MHz switching frequency to minimize external component size
• Housed in a thermally enhanced 16-pin TQFN package

Applications

• Industrial control systems requiring isolated or multi-rail power supplies
• Automotive electronics operating on 12V or 24V nominal buses
• Telecommunications infrastructure equipment
• Portable instrumentation powered by battery or adapter sources

Procurement Notes

Verify the specific suffix 'ATE+' indicates lead-free compliance and tape-and-reel packaging configuration. Confirm the manufacturer designation as Analog Devices Inc. following the Maxim Integrated acquisition. Ensure the order quantity matches the reel specifications provided by authorized distributors. Check for RoHS3 compliance status in the latest datasheet revision before finalizing procurement.

Selection Notes

Select this component when a single IC solution is needed for both switching regulation and LDO functionality. The wide input range accommodates noisy or variable supply lines common in industrial environments. Consider the thermal performance of the exposed pad design for high-current applications. Evaluate the 1MHz frequency against EMI requirements and inductor size constraints.

Part Context

This part belongs to the MAX5093 family of mixed-signal power management ICs. It combines the efficiency of a synchronous buck converter with the simplicity of an LDO. The series is targeted at applications needing reliable power conversion from higher voltage rails down to lower logic levels.

Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio that offer similar input ranges. Verify if newer revisions of the MAX5093 series provide updated thermal characteristics or packaging options.
