Procurement Notes
Verify the specific suffix 'AS' against official Diodes Incorporated documentation to confirm marking and tape/reel specifications. Ensure compatibility with required thermal management for the SOIC-8 package. Confirm RoHS compliance status through the manufacturer's latest environmental declaration before integration into production.
Selection Notes
Select this component for designs requiring integrated PFC and constant current regulation in a single IC. Consider the 80 kHz switching frequency for EMI filtering requirements. Evaluate the SOIC-8 footprint constraints against PCB layout guidelines provided in the datasheet to ensure adequate thermal dissipation and signal integrity.
Part Context
This part belongs to the AL1666 series of LED controllers from Diodes Incorporated. It is functionally related to variants such as AL1666S-13, differing primarily in packaging or marking details. The series targets cost-effective, high-reliability solutions for commercial and industrial LED lighting markets.
Replacement Considerations
Check for AL1666S-13 as a potential alternative if pinout and electrical characteristics match the design requirements. Verify that any substitute maintains the same SOIC-8 package dimensions and thermal performance.
