MAX20430ATIP/VY+

Power Management - Specialized Overview

The MAX20430ATIP/VY+ is a high-voltage, four-output DC-DC switching regulator IC designed for automotive applications. It operates with an input voltage range of 3.5V to 40V and provides four positive outputs with current ratings of 500mA, 2.5A, 3A, and 3A respectively. The device supports boost and buck topologies with a fixed switching frequency of 2.1MHz. Outputs are programmable or fixed at 0.8V, 3.3V, and 5V, reaching a maximum output voltage of 3.9875V. Packaged in a 28-SWTQFN (5x5mm) surface-mount case with exposed pad, it is qualified to AEC-Q100 standards and functions within a temperature range of -40°C to 125°C.

Power Management - Specialized Feature Summary

• Integrated four-output power management solution combining step-up and step-down regulators for compact system design
• Automotive-grade qualification ensuring reliability under harsh environmental conditions and wide operating temperatures
• High input voltage tolerance up to 40V suitable for direct connection to vehicle battery systems

Power Management - Specialized Applications

• Power supply for automotive compact radar systems
• High-voltage safety PMIC implementations
• Multi-rail power distribution in automotive electronic control units

Power Management - Specialized Procurement Notes

Verify the specific suffix variant, such as ATIA versus ATIP, as these denote different internal configurations or pinouts despite sharing the base model number. Confirm AEC-Q100 qualification status and ASIL compliance requirements match the target application safety integrity level. Ensure the 28-SWTQFN thermal pad soldering process aligns with PCB assembly capabilities to maintain thermal performance and mechanical stability during operation.

Power Management - Specialized Selection Notes

Select this component when a single IC must replace multiple discrete regulators to save board space in automotive designs. The 40V input range accommodates load dump conditions common in vehicle electrical systems. Consider the specific output current requirements of each rail to ensure the 500mA, 2.5A, and dual 3A channels meet the total system load without exceeding thermal limits in the confined QFN package.
