Procurement Notes
Verify the End-of-Life (EOL) status prior to procurement, as discontinuance notifications have been issued for this product family. Confirm that the specific suffix matches the required pinout and electrical characteristics, as variations exist within the series. Ensure compliance with RoHS and REACH regulations for the intended market. Check moisture sensitivity level (MSL 3) handling requirements during storage and assembly processes.
Selection Notes
Select this component for designs requiring a single-chip solution for AC-DC LED driving with multi-step dimming capabilities. It is appropriate for applications utilizing Flyback, SEPIC, Buck, or Boost topologies. Consider the 8-SOIC package constraints and thermal performance given the 663 mW power dissipation limit. Verify input voltage ranges against the 8.8V to 25.5V supply specification.
Part Context
This part belongs to the NCL30185 series of LED lighting controllers. It is functionally related to other variants such as the NCL30186 and NCL30170, which share similar packaging but may differ in specific electrical parameters or feature sets. The series targets general illumination markets requiring efficient AC-DC conversion and controlled LED output.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, alternative sourcing should focus on compatible devices from the same manufacturer or cross-reference with updated series components.
