Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes against official Texas Instruments documentation to ensure correct output configuration and package variant. Confirm AEC-Q100 certification requirements match specific vehicle safety integrity levels. Check moisture sensitivity classification and recommended reflow profiles prior to assembly planning.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V rail is required for automotive loads within the 3 V to 36 V input window. The 6 A current capability suits moderate power applications where space constraints favor the compact 22-pin QFN package. Ensure thermal design accounts for the 150°C maximum junction rating under expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM64460 family of high-efficiency synchronous buck converters designed for demanding automotive environments. It shares architectural similarities with other members like the LM64460APPQRYFRQ1 but differs in its fixed output voltage specification rather than adjustable output options.
