Procurement Notes
Verify the obsolete product status before procurement planning. Confirm the 8-SOP/8-SOIC package dimensions match your PCB footprint requirements. Ensure compatibility with existing AC-DC offline switcher designs. Check for available substitute part numbers if supply continuity is required. Validate that the 1.4A output rating meets specific load demands.
Selection Notes
Select this component for applications requiring a single-output buck converter with integrated switching elements. Consider the 1.4A current limit when sizing thermal management solutions. Verify that the 8-SOP package fits within spatial constraints. Evaluate dimming requirements against supported control methods. Confirm suitability for offline AC-DC conversion topologies.
Part Context
This IC belongs to the family of AC-DC offline switchers designed for LED driving. It shares functional similarities with variants such as the RT8497GS and RT8497AGS, which offer comparable buck topology and dimming features. The series targets general lighting applications requiring compact, integrated power solutions.
Replacement Considerations
Publicly confirmed substitutes include RT8497GS and RT8497AGS. These variants share similar buck topology and dimming capabilities. Verify pinout compatibility and package dimensions before substitution.
