MP2489DQ-LF-P

LED Driver IC Overview

The MP2489DQ-LF-P is a Monolithic Power Systems LED lighting driver IC featuring a buck topology. It supports an input voltage range of 6 V to 60 V and delivers up to 1 A output current. The device operates at a fixed switching frequency of 600 kHz and utilizes a QFN-6 package. It is qualified under AEC-Q100 standards for automotive applications, ensuring reliability within a temperature range of -40°C to +125°C.

LED Driver IC Feature Summary

• Integrated high-voltage buck converter architecture designed for white LED driving
• Supports both analog and PWM dimming control methods
• Includes short circuit and thermal protection mechanisms

LED Driver IC Applications

• Automotive exterior lighting systems
• General LED illumination circuits
• High-voltage LED string drivers

LED Driver IC Procurement Notes

Verify the specific suffix 'AEC1' against the datasheet to confirm automotive qualification status, as standard variants may differ. Ensure the QFN-6 package footprint matches the target PCB layout. Confirm RoHS compliance details directly with the manufacturer documentation before finalizing procurement specifications.

LED Driver IC Selection Notes

Select this component when a wide input voltage range up to 60 V is required for single-channel LED applications. The fixed 600 kHz frequency allows for compact passive component selection. Consider the QFN-6 package constraints for thermal management in high-current scenarios compared to larger packages.

LED Driver IC Part Context

This part belongs to the MPS MP2489 series of LED drivers. It shares functional similarities with the MP24893 but offers higher input voltage tolerance. The MP2489DQ-LF-P is distinct from the MPQ2489DQ-AEC1-LF-P, which also carries automotive qualification but may have different internal characteristics or packaging options.

LED Driver IC Replacement Considerations

The MP24893DQ-LF-P is a related variant but is limited to a 36 V maximum input voltage. Verify if the lower voltage rating of the MP24893 meets the specific application requirements before substituting.
