LED Driver IC datasheet and documents for LP5009RUKR
LED Driver IC Overview
The LP5009RUKR is a nine-channel LED lighting driver IC manufactured by Texas Instruments, housed in a WQFN-20 package. It operates as a boost converter with an input voltage range of 2.7 V to 5.5 V and delivers up to 35 mA per channel. The device features I2C control for constant current regulation and supports RGB applications. It functions within a temperature range of -40°C to +85°C.
LED Driver IC Feature Summary
- Nine independent output channels for multi-color LED arrays
- I2C interface for digital control and configuration
- Constant current regulation for consistent brightness
- Boost topology supporting high-voltage LED strings
LED Driver IC Applications
- RGB LED backlighting systems
- Multi-channel LED indicator arrays
- Digital display illumination modules
- Compact LED lighting fixtures requiring I2C control
LED Driver IC Procurement Notes
Verify the specific suffix RUKR against the official datasheet to confirm package type and tape-and-reel specifications. Ensure the design accounts for the WQFN-20 thermal requirements and I2C address settings. Confirm RoHS compliance status through the manufacturer's documentation before finalizing procurement.
LED Driver IC Selection Notes
Select this component when nine individually controllable constant-current outputs are required from a single IC. It is suitable for designs needing I2C communication rather than analog dimming. Verify that the input voltage range of 2.7 V to 5.5 V aligns with the system power supply and that the boost topology meets the LED forward voltage requirements.
LED Driver IC Part Context
The LP5009 belongs to Texas Instruments' LP series of LED drivers, designed for efficient and compact lighting solutions. This specific model integrates multiple channels into a small footprint, reducing board space compared to discrete solutions. It targets applications requiring precise color mixing and digital control in consumer and industrial electronics.
LED Driver IC Replacement Considerations
