Procurement Notes
Verify component authenticity through authorized Diodes Incorporated channels or certified distributors. Confirm RoHS compliance status via the official datasheet before integration. Ensure the SO-7 package variant matches design requirements. Check for end-of-life notifications as availability may be limited. Validate electrical parameters against specific application needs prior to procurement.
Selection Notes
Select this component for designs requiring high power factor correction in offline LED applications. The wide input voltage range suits universal AC mains operation. Ensure the 2A output current aligns with LED string requirements. Verify that the SO-7 package fits the PCB layout constraints. Consider the 4kHz switching frequency for EMI management in the final system design.
Part Context
This part belongs to the AL1676 series of offline LED drivers by Diodes Incorporated. It shares functional similarities with other members like the AL1676-40DS7-13 but differs in output current specifications.
