MAX20430ATIE/VY+

Power Management - Specialized Overview

The MAX20430ATIE/VY+ is a high-voltage, automotive-grade DC-DC converter IC featuring four non-isolated outputs. It operates within an input voltage range of 3.5V to 40V and utilizes a 2.1MHz switching frequency. The device provides three programmable buck outputs rated at 3A each and one boost/buck output rated at 500mA. It is housed in a 28-SWTQFN (5x5) package with exposed thermal pads for efficient heat dissipation.

Power Management - Specialized Feature Summary

• Automotive-grade reliability compliant with AEC-Q100 standards
• Integrated synchronous rectification for improved efficiency
• Flexible topology supporting both buck and boost configurations
• Compact surface-mount packaging designed for thermal performance

Power Management - Specialized Applications

• Automotive compact radar systems
• High-voltage power management in ASIL-rated applications
• Multi-rail power distribution for electronic control units
• Industrial power supplies requiring wide input ranges

Power Management - Specialized Procurement Notes

Verify the specific suffix 'ATIE/VY+' against the manufacturer's official datasheet to confirm the exact temperature grade and tape-and-reel specifications. Ensure that the ordering documentation explicitly references the Analog Devices or Maxim Integrated part number to avoid confusion with similar family members. Cross-reference the RoHS and REACH compliance status with the latest product release notes prior to finalizing procurement orders.

Power Management - Specialized Selection Notes

Select this component when designing systems requiring a single-chip solution for multiple voltage rails from a high-voltage source. The integrated nature of the four outputs reduces bill-of-materials complexity compared to discrete regulator designs. Consider the 2.1MHz switching frequency for balancing electromagnetic interference filtering requirements against passive component size constraints in space-limited automotive enclosures.

Power Management - Specialized Part Context

This part belongs to the MAX20430 series of specialized power management integrated circuits developed for demanding automotive environments. The series is engineered to meet stringent automotive quality and safety standards, providing robust power conversion capabilities. It serves as a critical component in modern vehicle electronics where reliable operation under varying load and temperature conditions is mandatory.

Power Management - Specialized Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitute part numbers. Ensure any replacement maintains compatibility with the 28-SWTQFN footprint and meets the same AEC-Q100 qualification level. Verify that alternative devices support the required 40V maximum input voltage and provide equivalent current ratings for all four channels.
