MPQ3386DR-LF-Z

Overview

The MPQ3386DR-LF-Z is a Monolithic Power Systems LED lighting driver IC designed for industrial applications. It features a boost topology with six independent output channels, specifically configured for driving white LEDs. The device operates within an input voltage range of 4.5 V to 25 V and supports a switching frequency of 1.25 MHz. Packaged in a QFN-24 format, it is rated for power dissipation up to 2.9 W. The component functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Six-channel architecture for simultaneous white LED string control
• Industrial-grade operational stability across wide thermal ranges
• Integrated boost converter topology for efficient voltage step-up

Applications

• Industrial white LED lighting systems
• Multi-string LED backlighting arrays
• High-reliability automotive or commercial illumination modules

Procurement Notes

Verify the specific suffix against official MPS documentation to confirm industrial qualification status. Ensure the ordering part number matches the required package variant and environmental rating. Cross-reference the manufacturer datasheet for any recent design revisions or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring six independent LED strings driven by a single controller. It is suitable for applications demanding high efficiency via boost conversion and robust performance under varying input voltages. Consider the QFN-24 footprint for compact PCB layouts requiring adequate thermal management capabilities.

Part Context

This part belongs to the MPQ3386 series of LED drivers from Monolithic Power Systems. It shares core architectural similarities with other members like the MPQ3386DR-AEC1-LF-Z but differs in its specific industrial qualification and lack of automotive AEC-Q100 certification. It serves as a specialized solution for non-automotive high-density lighting designs.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative MPS LED drivers based on channel count and boost topology requirements if direct substitution is necessary.
