- Constant current LED driving circuits
Procurement Notes
This component is officially classified as obsolete by the manufacturer. Production has ceased, and no new units will be stocked once existing inventory is depleted. Engineers should verify the availability of alternative sources or consider redesigning with currently available components to ensure long-term supply chain stability.
Selection Notes
Select this part only if legacy compatibility with the FT883 series is required. Verify that the 35mA output current and 5kHz switching frequency align with specific load requirements. Ensure the 8-SOP package footprint matches the PCB layout constraints. Due to its obsolete status, confirm end-of-life implications before finalizing the design.
Part Context
The FT883A-RT belongs to the FT883 family of LED drivers from Fremont Micro Devices Ltd. This series focuses on integrated solutions for AC/DC offline applications, combining switching regulation and LED drive functions into a single compact package. The RT suffix indicates a specific tape-and-reel packaging configuration.
Replacement Considerations
No public confirmed substitute part numbers are documented for this obsolete component. Designers must evaluate cross-reference options independently based on electrical specifications and pinout compatibility.
