MP2489DJ-LF-P

LED Driver IC Overview

The MP2489DJ-LF-P is a step-down white LED driver IC from Monolithic Power Systems. It operates with an input voltage range of 6V to 60V and provides a regulated output current of 1A. The device utilizes a buck topology and supports a switching frequency of 600kHz. It features both analog and PWM dimming capabilities for brightness control. The component is housed in a TSOT-23-5 package and is designed for operation within a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Supports wide input voltage range from 6V to 60V
• Integrates internal power switch for compact design
• Enables precise LED current regulation up to 1A
• Offers flexible dimming via analog or PWM signals

LED Driver IC Applications

• White LED lighting systems
• General illumination drivers
• Battery-powered LED applications

LED Driver IC Procurement Notes

Verify the specific suffix 'LF-P' against the manufacturer's official documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the ordering part number matches the required package variant, as suffixes may indicate differences in reel quantity or environmental compliance. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

LED Driver IC Selection Notes

Select this component for designs requiring a single-channel buck LED driver with high input voltage tolerance. The 1A output current capability suits medium-power LED strings. Consider the TSOT-23-5 package size for space-constrained PCB layouts. Verify that the application requires a fixed 600kHz switching frequency, as other variants in the series may offer different frequencies.

LED Driver IC Part Context

This part belongs to the MP2489 family of LED drivers from Monolithic Power Systems. The family includes variants with different input ranges, such as the MP24893 which supports up to 36V. The MP2489DJ-LF-P specifically targets higher voltage inputs up to 60V. It shares functional similarities with other MPS buck LED drivers but is distinguished by its specific voltage rating and package type.

LED Driver IC Replacement Considerations

The MP2489DJ-LF-Z is a direct pin-compatible alternative within the same series, differing primarily in packaging format (reel vs. cut tape). Designers should verify if the change in packaging affects handling requirements or inventory management without altering electrical performance.
