Overview
The KTD2686EUD-TR is a flash LED driver IC manufactured by Kinetic Technologies, designed for mobile camera applications. It features three independent output channels with configurable current capabilities of 1.5 A, 1 A, and 0.5 A, supporting a total peak output of 1.8 A. The device utilizes a boost topology and operates within an input voltage range of 2.7 V to 5.5 V. It supports switching frequencies of 2 MHz and 4 MHz to optimize external component size. Packaged in a WLCSP-12 format, it integrates protection features suitable for compact smartphone designs.
Feature Summary
- Provides three independent output channels with distinct current ratings for flexible LED configuration
- Integrates a boost converter topology to drive high-voltage flash LEDs from low input sources
- Supports dual switching frequency options to balance efficiency and passive component size
Applications
- Smartphone camera flash systems
- Mobile device illumination modules
- Compact electronic imaging devices requiring multi-channel LED control
Procurement Notes
Verify the specific suffix and package variant against the manufacturer's latest datasheet before ordering. Confirm that the WLCSP-12 footprint matches your PCB layout requirements. Ensure compatibility with the required 2 MHz or 4 MHz switching frequency settings for your power stage design. Cross-reference the part number with official distributor catalogs to confirm availability and authenticity.
Selection Notes
Select this component when designing mobile camera systems requiring independent control over multiple flash LEDs. It is suitable for applications needing up to 1.8 A total peak current distributed across three channels. Consider the WLCSP-12 package constraints for board space limitations. Verify that the input voltage range aligns with the system's battery profile during discharge cycles.
Part Context
This part belongs to Kinetic Technologies' portfolio of LED lighting driver ICs specialized for consumer electronics. It complements other models like the KTD2692EJH-TR by offering multi-channel independence rather than single-channel high-current delivery. The series focuses on integrating power stages and control logic into minimal footprints for portable devices.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Evaluate alternative drivers based on channel count, current limits, and package compatibility if sourcing issues arise.
