MAX16911AUE/V+T

Overview

The MAX16911AUE/V+T is an automotive-grade power management integrated circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It functions as a miniaturized buck converter designed for high-efficiency voltage step-down applications in vehicle electronics. The device operates within an input voltage range of 4.5V to 36V, delivering a maximum output current of 2.5A. It features a fixed switching frequency of 1.2MHz and supports adjustable output voltages. The component is qualified to AEC-Q100 standards and housed in a compact 16-pin TSSOP package with an exposed pad for thermal dissipation.

Feature Summary

• Automotive qualification compliant with AEC-Q100 standards for reliability
• Miniaturized buck converter topology for space-constrained designs
• High switching frequency enabling small external component size
• Integrated protection mechanisms for robust operation

Applications

• Infotainment system power distribution
• Telematics control unit voltage regulation
• Body control module power supplies
• Sensor interface circuitry powering

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to obsolete status. Confirm lot traceability and RoHS compliance documentation prior to acquisition. Ensure storage conditions meet specified humidity sensitivity levels to prevent lead frame corrosion. Validate that the specific suffix matches design requirements for temperature grade and packaging format.

Selection Notes

Select this component when designing automotive systems requiring a compact, high-frequency step-down solution with proven automotive reliability. Consider the fixed 1.2MHz frequency for minimizing passive component footprint. Evaluate the 2.5A current limit against peak load demands. Ensure the 36V input tolerance aligns with vehicle bus transients. Compare thermal performance in the TSSOP-EP package against alternative packages if heat dissipation is critical.
