Procurement Notes
Verify the specific suffix and package variant against official MaxLinear documentation, as the XR46084 family includes multiple pin-compatible options such as SOT-89-5 and WDFN packages. Confirm lifecycle status, as some variants are marked obsolete. Ensure compatibility with existing PCB footprints and thermal requirements before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring integrated Triac dimming control in space-constrained designs. The absence of electrolytic capacitors reduces mechanical cost and improves reliability. Verify that the input voltage range and output current requirements align with the target LED load specifications.
Part Context
This part belongs to the XR46084 series of LED drivers from MaxLinear. The series focuses on high-voltage AC offline switching applications. Variants differ primarily by package type and specific electrical characteristics, serving general-purpose LED illumination needs.
Replacement Considerations
Check for direct substitutes within the XR46084 or XR46110 families. Verify pinout compatibility and thermal performance if replacing with other manufacturers' parts.
