Procurement Notes
Verify the exact suffix 'TBR' against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as availability may vary due to production lifecycle changes. Ensure compatibility with existing PCB footprints for the 25-TFBGA form factor before procurement.
Selection Notes
Select this component when designing camera flash circuits requiring integrated buck-boost regulation within a minimal footprint. The I2C interface allows for software-controlled brightness adjustments, suitable for modern mobile devices. Verify that the 800mA peak current capability meets the specific LED array requirements and that the 1.8MHz switching frequency aligns with EMI constraints in the design.
Part Context
This part belongs to STMicroelectronics' family of LED drivers optimized for portable electronics. It addresses the need for efficient power management in space-constrained mobile devices. The integration of control logic and power stages reduces external component count compared to discrete solutions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult STMicroelectronics technical support or authorized distributor databases for direct replacements or pin-compatible alternatives.
