Procurement Notes
Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance status and check for End-of-Life (EOL) notifications, as this part may be discontinued. Ensure the specific suffix matches the required package variant and that all electrical parameters align with system requirements before procurement.
Selection Notes
Select this component when a small form factor is critical due to its TSOT-23-6 packaging. Choose this model if the application requires a single-output boost configuration with integrated switching capability. Consider the 1MHz frequency for minimizing external passive component sizes while maintaining stable LED current regulation.
Part Context
This part belongs to the RT9285 series of LED drivers from Richtek Technology Corporation. The series focuses on providing efficient power management solutions for portable electronics. The BGJ6 suffix indicates the specific package type and tape-and-reel configuration used for automated assembly processes.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Consult official cross-reference lists from Richtek or verify compatibility with equivalent boost LED drivers featuring similar pinouts and electrical characteristics.
