Procurement Notes
Verify the complete part number including suffixes to ensure correct packaging and automotive qualification status. Confirm that the TSOT23-8 package matches the target PCB footprint and thermal requirements. Cross-reference the AEC-Q100 grade against specific project reliability standards. Ensure the operating temperature range aligns with the intended installation environment within the vehicle.
Selection Notes
Select this component when a compact solution for single-string LED driving is required in space-constrained automotive designs. The wide input voltage range accommodates load dump and cold crank conditions typical in automotive environments. Consider the adjustable frequency to minimize EMI interference with other sensitive onboard electronics while maintaining efficient power conversion.
Part Context
This part belongs to the MPS automotive-grade LED driver portfolio, specifically targeting high-reliability lighting applications. It complements other buck converters and smart switches in the MPQ series by providing dedicated boost functionality for forward-facing or accent lighting needs.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Direct replacement requires matching the boost topology, voltage ratings, and AEC-Q100 qualification independently.
