DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'GETQ1' matches the required 24-VQFN package and tape-and-reel configuration. Confirm that the AEC-Q100 grade aligns with the target automotive application's thermal and reliability requirements. Ensure compatibility with the intended PCB footprint and soldering profile for the exposed pad thermal design.

DC DC Switching Controllers Selection Notes

Select this component when a wide input voltage range up to 42V is required alongside low quiescent current. It is suitable for designs needing a fixed 2.2MHz frequency to minimize passive component size. Consider alternatives if higher output currents or different topologies are necessary.

DC DC Switching Controllers Part Context

This part belongs to the LM25141-Q1 family of wide-input synchronous buck controllers. It shares architectural similarities with the LM5141 but offers optimized performance for lower input voltage ranges and specific automotive thermal profiles. The series focuses on compact solutions for high-density power management.
