Procurement Notes
Verify the specific suffix 'SP-13' against the manufacturer's latest datasheet to confirm packaging details and tape-and-reel specifications. Ensure compatibility with the target PCB footprint, specifically the 8-SO-EP exposed pad configuration. Confirm RoHS compliance status through official documentation before integration into regulated environments.
Selection Notes
Select this component when a single-channel, high-input voltage buck driver is required. It is suitable for designs needing up to 1A output current with integrated switching elements. Consider the 8-SO-EP package for thermal performance requirements. Verify that the application does not require multiple independent channels or higher current capacities than 1A.
Part Context
This part belongs to the AL8866 series of LED drivers from Diodes Incorporated. The series focuses on high-voltage, single-output solutions for general lighting. The SP-13 designation typically indicates the specific reel quantity and packaging format provided by the distributor.
Replacement Considerations
The AL8862SP-13 is a related part in the same family but may differ in specific electrical characteristics or feature sets. Verify pinout compatibility and exact current ratings before substitution.
