MPQ3386DR-AEC1-LF-P

Overview

The MPQ3386DR-AEC1-LF-P is an automotive-grade step-up converter featuring six independent current sources, designed for driving white LED arrays in large LCD panel backlighting applications. It operates within a supply voltage range of 4.5 V to 25 V and supports output voltages up to 50 V. The device integrates a fixed switching frequency of 1.25 MHz and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a QFN-24 format, it meets AEC-Q100 qualification standards for automotive reliability.

Feature Summary

• Integrates six independent constant-current channels for precise LED array control
• Automotive qualification compliant with AEC-Q100 standards
• Fixed high-frequency operation eliminates external inductor size requirements
• Designed specifically for large-size LCD panel backlighting systems

Applications

• Large size LCD panel backlighting
• White LED array driving
• Automotive display systems

Procurement Notes

Verify the specific suffix 'LF-P' against official Monolithic Power Systems documentation to confirm lead-free status and tape-and-reel packaging configuration. Ensure the component matches the required AEC-Q100 grade for your target application. Cross-reference the datasheet revision date to validate technical specifications before integration into production designs.

Selection Notes

Select this component when designing automotive displays requiring six-channel LED regulation. It is suitable for applications needing a boost topology with a wide input voltage range. Consider the QFN-24 package constraints for thermal management. Verify that the 1.25 MHz switching frequency aligns with electromagnetic interference requirements of the host system.

Part Context

This part belongs to the MPQ3386 series of multi-channel LED drivers manufactured by Monolithic Power Systems. It is the automotive-qualified variant of the MP3386, distinguished by its extended temperature rating and AEC-Q100 certification. The series is engineered to replace discrete solutions with a highly integrated IC approach for automotive lighting.

Replacement Considerations

The non-automotive MP3386DR-LF-P is a related component but lacks AEC-Q100 qualification and has a limited operating temperature range of -40°C to +85°C. Direct substitution requires verifying if the reduced temperature rating and lack of automotive certification meet the specific design requirements.
