MP3306EG-LF-P

LED Driver IC Overview

The MP3306EG-LF-P is a synchronous boost LED driver IC from Monolithic Power Systems, designed for white LED (WLED) applications. It features an integrated disconnect FET and supports a maximum output voltage of 30 V with a peak output current of 1.8 A. The device operates on a supply voltage range of 3 V to 12 V and utilizes a fixed switching frequency of 690 kHz. Packaged in a QFN-12 format, it is rated for operation between -40°C and +125°C.

LED Driver IC Feature Summary

• Integrated internal disconnect FET for enhanced safety and control
• Synchronous boost topology for improved power conversion efficiency
• Fixed high-frequency operation to minimize external component size

LED Driver IC Applications

• White LED backlighting for portable electronic devices
• Mobile phone display illumination systems
• General-purpose LED lighting drivers requiring compact form factors

LED Driver IC Procurement Notes

Verify the specific suffix 'P' indicates cut-tape packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation. Ensure the QFN-12 package dimensions match your PCB footprint requirements. Cross-reference the datasheet revision date to confirm technical specifications have not changed.

LED Driver IC Selection Notes

Select this component for designs requiring a single-output WLED driver with integrated protection. The 1.8 A current capability suits medium-brightness LED strings. The 3 V to 12 V input range accommodates single-cell lithium battery systems. Consider thermal performance within the QFN-12 package for high-duty-cycle applications.

LED Driver IC Part Context

This part belongs to the MP3306 series of LED drivers. It shares functional similarities with other MPS WLED controllers but is distinguished by its specific 30 V output limit and integrated disconnect feature. The LF designation typically indicates lead-free manufacturing processes compliant with environmental standards.

LED Driver IC Replacement Considerations

Direct substitutes include MP3306EG-LF-Z, which differs primarily in packaging format rather than electrical function. Verify pin compatibility and thermal characteristics when transitioning between packaging variants.
