Procurement Notes
Verify component authenticity through authorized channels, as the AL8821SP-13 is listed as obsolete or discontinued by major distributors. Confirm final availability status directly with the manufacturer or certified suppliers before initiating procurement processes. Ensure compliance with RoHS standards and check for moisture sensitivity levels during storage handling.
Selection Notes
Select this component for designs requiring a compact boost topology with a 36V input limit and 2A output capability. The 1 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the SO-8EP package for thermal performance and board space constraints in single-channel LED applications.
Part Context
This part belongs to the AL88 series of LED drivers from Diodes Incorporated. It is categorized under Power Management ICs (PMIC) specifically for LED Lighting Drivers. The device serves as a specialized solution for converting lower input voltages to higher levels required by LED strings in various lighting fixtures.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. As the component is marked as obsolete, engineers should consult the manufacturer's official obsolescence notices or cross-reference guides for equivalent active parts.
