MAX5092BATE+

Overview

The MAX5092BATE+ is a dual-output power management IC combining a synchronous buck converter and an LDO. It accepts input voltages from 4V to 72V. The buck output provides adjustable voltage up to 11V at 600mA with a 1MHz switching frequency. The LDO supports inputs up to 72V. Operating temperature range is -40°C to 125°C TJ. Package is 16-TQFN (5x5).

Feature Summary

• Integrates a high-voltage step-down converter and a linear regulator in a single package.
• Supports wide input voltage ranges suitable for industrial and automotive bus systems.
• Features synchronous rectification for improved efficiency in the buck stage.

Applications

• Industrial control systems requiring isolated or non-isolated power rails.
• Automotive electronics operating on 12V, 24V, or 48V architectures.
• Aerospace avionics power distribution networks.

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status and AEC-Q100 qualification if required for automotive applications. Check current production status as part numbers may be discontinued or superseded by newer revisions.

Selection Notes

Select this component when a combined buck and LDO solution is needed for space-constrained designs. Ensure the input voltage does not exceed the 72V absolute maximum rating. Verify that the thermal performance of the 16-TQFN package meets the application's heat dissipation requirements under full load conditions.

Part Context

This device belongs to the MAX509x family of high-voltage power management ICs designed for harsh environments. It addresses the need for compact power solutions in systems where multiple regulated outputs are derived from a single high-voltage source.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic replacements may differ in pin compatibility or thermal performance.
