Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 qualification for automotive use. Confirm the 'T' suffix indicates tape-and-reel packaging. Check the datasheet revision date to ensure compatibility with your design requirements. Validate that the SOIC-8 package dimensions match your PCB footprint constraints before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 60 V is required in a compact SOIC-8 package. It is suitable for designs needing adjustable switching frequencies to minimize passive component size. Consider the thermal performance of the PowerPAD package for high-current applications. Ensure the load profile benefits from Eco-mode efficiency improvements at light loads.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS5436x-Q1 family of high-voltage synchronous buck converters. It shares core architecture with the non-automotive TPS54361 but meets stricter automotive reliability standards. The family offers various package options including WSON and SOIC variants to suit different thermal and space constraints in automotive electronics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

TPS54361DPRT is the commercial grade equivalent without automotive qualification. TPS54360QDDARQ1 offers similar electrical specifications but uses an 8-SO-PowerPad package instead of SOIC-8. Verify pin-to-pin compatibility and thermal characteristics when substituting.
