KTD2026CEWE-TR

Overview

The KTD2026CEWE-TR is a 3-channel RGB LED driver IC manufactured by Kinetic Technologies. It features an I2C control interface and operates within a supply voltage range of 2.7 V to 5.5 V. The device provides constant current outputs with a maximum output current of 24 mA per channel. It utilizes Boost and Buck topologies for adjustable output voltages. The component is housed in an 8-pin UTDFN package measuring 1.5x1.5 mm. It supports dimming functions and operates reliably across a temperature range of -40°C to +85°C, with a maximum power supply current of 650 µA.

Feature Summary

• Integrates three independent constant current channels specifically configured for RGB LED applications.
• Utilizes a two-wire I2C serial interface for programmable control and data transmission.
• Incorporates both boost and buck converter topologies to manage LED drive voltages efficiently.
• Supports digital dimming capabilities for precise brightness adjustment.

Applications

• RGB LED backlighting systems
• Small LCD bias power circuits
• Portable electronic display modules

Procurement Notes

Verify the specific suffix 'CEWE' against the manufacturer's official documentation to confirm pinout and functional compatibility. Ensure the ordering quantity aligns with the specified reel or cut tape packaging requirements. Confirm RoHS compliance status through the provided datasheet before finalizing procurement decisions.

Selection Notes

Select this component when a compact solution for driving three distinct RGB channels is required. The small 1.5x1.5 mm footprint makes it suitable for space-constrained designs. Verify that the system voltage falls within the 2.7 V to 5.5 V operating range and that I2C communication lines are available for control.

Part Context

This part belongs to the KTD2026 series from Kinetic Technologies, designed as a dedicated LED lighting driver. It is often compared with related models like the KTD2027EWE-TR, which offers four channels instead of three. Both share similar control interfaces and physical dimensions but differ in channel count and specific application targeting.

Replacement Considerations

The KTD2027EWE-TR serves as a direct substitute if a fourth channel is needed, maintaining the same package and interface. Other Kinetic Technologies RGB drivers may require schematic adjustments due to differing channel counts or pin configurations.
