Overview
The KTD2042EUAC-TR is a 9-channel RGBW LED driver IC manufactured by Kinetic Technologies. It integrates a step-down (Buck) DC/DC regulator and supports I2C and PWM dimming interfaces. The device delivers an output current of 32 mA per channel with adjustable voltage control. It operates within a supply voltage range of 2.5 V to 5.5 V and features a switching frequency of 1 MHz. The component is housed in a 20-UQFN (3x3 mm) package, suitable for surface mount installation, and functions reliably across temperatures from -40°C to +85°C.
Feature Summary
- Integrates a Buck regulator for efficient power management in RGBW LED applications
- Supports digital control via I2C interface and analog dimming through PWM signals
- Provides constant current drive capability for multiple LED channels
Applications
- RGBW LED lighting systems requiring integrated regulation
- Portable electronic devices utilizing space-constrained SMD packages
- Display backlighting modules needing precise current control
Procurement Notes
Verify the specific suffix and package type against official manufacturer documentation before procurement. Ensure compatibility with I2C bus voltage levels and confirm thermal requirements for the UQFN footprint. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate that the Buck regulator topology aligns with the target LED load characteristics.
Selection Notes
Select this component when a compact solution combining LED driving and buck conversion is required. The 32 mA output current suits standard RGBW configurations. Consider the 20-pin UQFN package for PCB area constraints. Verify that the 1 MHz switching frequency meets EMI requirements for the specific application environment.
Part Context
This part belongs to the Kinetic Technologies LED driver family, designed for high-density lighting solutions. It complements other models like the KTD2052 and KTD2061 by offering a specific 9-channel RGBW configuration with integrated power regulation. The series emphasizes low component count and simplified design integration for modern LED applications.
Replacement Considerations
Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternative Kinetic models such as the KTD2041 or KTD2052 based on channel count and topology differences. Ensure pinout and electrical specifications match the existing design constraints before substitution.
