KTD2061EUAC-TR

Overview

The KTD2061EUAC-TR is a 36-channel RGB LED driver IC from Kinetic Technologies, designed for high-density lighting applications. It features integrated Boost and Buck topologies with an adjustable output voltage. The device operates on a supply voltage range of 2.5 V to 5.5 V and supports a working frequency of 1 MHz. Each channel delivers a maximum output current of 24 mA via multiplexed constant current outputs. Controlled via I2C interface, it includes hardware dimming engines and programmable rates. The component is housed in a 20-pin UQFN package (3 mm × 3 mm) and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates Boost and Buck converter topologies for flexible LED power management
• Supports up to 36 LEDs through a multiplexed 4-wire bus architecture
• Includes independent hardware dimming engines with programmable rates per LED
• Features automatic reduction of current absorption voltage drop

Applications

• AI speaker ambient lighting
• Bluetooth and Wi-Fi speaker illumination
• Automotive interior context lighting
• IoT devices and gaming keyboard backlighting

Procurement Notes

Verify the specific suffix 'EUAC' against the manufacturer's official documentation to confirm pinout compatibility and thermal characteristics. Ensure the I2C address configuration matches the system design requirements. Confirm that the UQFN-20 package dimensions align with the PCB footprint specifications. Validate that the operating temperature range meets the environmental constraints of the final assembly.

Selection Notes

Select this component for designs requiring high channel density with minimal PCB trace count. The integrated power stages simplify schematic design by reducing external inductor and capacitor requirements. Consider the 1 MHz switching frequency for EMI management and filter size optimization. Evaluate the 24 mA per channel limit against total LED array current demands to ensure adequate brightness without exceeding thermal limits.
