Overview
The XRP6840AILBTR-F is a specialized LED driver IC from MaxLinear, designed for high-performance lighting applications. It features three independent output channels, each capable of delivering up to 1.43A of current. The device utilizes a switched-capacitor topology and supports I2C dimming control for precise regulation. Packaged in a 20-lead TQFN format, it is optimized for camera flash and general illumination systems requiring efficient power management.
Feature Summary
- Three-channel architecture with individual current regulation capabilities
- Integrated I2C interface for digital dimming and configuration
- Switched-capacitor topology for efficient voltage conversion
- Compact surface-mount packaging suitable for space-constrained designs
Applications
- Camera flash LED drivers

- General solid-state lighting applications
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix 'F' indicates RoHS compliance status as per official documentation. Ensure compatibility with existing PCB footprints and thermal management requirements before integration into final assemblies.
Selection Notes
Select this component when multi-channel LED control with digital interface is required. Consider the 1.43A per channel limit for load matching. Evaluate the TQFN package for thermal dissipation needs. Compare against single-channel alternatives if fewer outputs suffice for the target application design.
Part Context
This part belongs to the XRP6840 series of LED drivers. It shares functional similarities with variants like the XRP6840ILB-F but differs in specific electrical characteristics and packaging options. The series targets portable electronics and imaging devices requiring compact, efficient LED power solutions.
Replacement Considerations
Check for pin-compatible alternatives within the same MaxLinear family. Verify that substitute parts support the required three-channel configuration and I2C communication protocol. Ensure thermal performance matches the original design constraints.
