Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification status against the manufacturer's official datasheet. Confirm the package type matches the required PCB footprint. Ensure the fixed 1.8V output aligns with the target load requirements. Check for any recent product change notices regarding pinout or thermal characteristics.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when automotive reliability is required alongside compact size. The 2MHz frequency allows for smaller external passive components compared to lower-frequency converters. Consider the fixed 1.8V output constraint; if adjustable voltage is needed, choose a different variant within the LM3671 family. Evaluate thermal performance based on the small DSBGA-5 package dimensions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM3671 series of step-down DC-DC converters from Texas Instruments. The series offers various fixed and adjustable output voltages. The 'Q' designation typically signifies automotive-grade qualification, distinguishing it from standard commercial variants like the LM3671MF or LM3671TL series.
