KTD2688AEUR-TR

Overview

The KTD2688AEUR-TR is a two-channel flash LED driver IC manufactured by Kinetic Technologies. It utilizes a boost topology to drive high-current LEDs with independent current control for each channel. The device supports an input voltage range of 2.7 V to 5.5 V and operates at switching frequencies of 2 MHz or 4 MHz. It delivers a maximum output current of 1.5 A per channel, with a specific torch current rating of 375 mA. The component is housed in a WLCSP-12 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Independent current control for dual output channels
• Integrated boost converter topology for LED driving
• Supports programmable switching frequencies

Applications

• Smartphone camera flash systems
• Mobile device torch lighting
• Compact electronic imaging modules

Procurement Notes

Verify the exact datasheet revision (e.g., 04b) against the manufacturer's official documentation before integration. Confirm that the WLCSP-12 package dimensions align with the PCB footprint design. Ensure the selected switching frequency configuration matches the external inductor specifications required for the target application efficiency.

Selection Notes

Select this component when independent dual-channel control is required for flash and torch operations. The WLCSP-12 package offers a compact solution suitable for space-constrained mobile devices. Consider the 2 MHz/4 MHz frequency options based on available passive component sizes and efficiency requirements.
