Procurement Notes

This component has reached its end-of-life stage and is scheduled for obsolescence by the manufacturer. Availability is limited to existing stock or last-time buys. Verify specific ordering suffixes against official documentation to ensure correct package and temperature ratings. Cross-reference replacement part numbers carefully, as functional equivalents may differ in control protocols or voltage limits. Confirm final procurement details directly with authorized distributors before placing orders.

Selection Notes

Select this IC for applications requiring a compact, high-efficiency boost converter for LED strings. The integrated diode simplifies PCB layout compared to discrete solutions. Ensure the design accommodates the 30V OVP limit. The choice between PWM and I2C control depends on the host system's interface capabilities. External resistor selection determines the specific current range required for the target LED configuration.

Part Context

Kinetic Technologies specializes in LED driver ICs for various lighting and display applications. This model belongs to their step-up driver family, designed for efficiency and minimal external parts. Similar products in the lineup include multi-channel backlight drivers and RGB controllers, catering to different panel sizes and complexity requirements.

Replacement Considerations

The KTD2801ECD-TR is a confirmed substitute part number from the same manufacturer. Note that the replacement utilizes ExpressWire control instead of I2C/PWM and offers a higher 36V OVP rating. Verify compatibility with existing control logic before switching.
