Procurement Notes
Verify the specific ordering suffix and marking code (e.g., KLY or KLYYZ) against the manufacturer's latest datasheet to ensure component authenticity. Confirm package dimensions match the 10-uDFN (2x2) specification during PCB layout review. Cross-reference the part number with official distributor catalogs to validate active status and availability before finalizing procurement plans.
Selection Notes
Select this component for applications requiring a compact solution for high-current LED flashing with minimal external components. The 2MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the design accommodates the single-wire dimming interface requirements and that the input voltage range aligns with the system power supply rails.
Part Context
This part belongs to Kinetic Technologies' portfolio of LED lighting drivers, specifically designed for mobile consumer electronics. It complements other models like the KTD2688AEUR-TR by offering a single-channel configuration optimized for space-constrained designs where single-wire control is preferred over multi-line interfaces.
Replacement Considerations
Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternative single-channel boost LED drivers from Kinetic Technologies or other manufacturers, ensuring compatibility with the 1.5A current rating, 2MHz frequency, and 10-uDFN package footprint.
FAQ
What is the maximum flash current supported by the KTD2694EDQ-TR?
The device supports a maximum output current of 1.5A for flash applications.
Does the KTD2694EDQ-TR support PWM dimming?
