MP3351DQ-LF-P

LED Driver IC Overview

The MP3351DQ-LF-P is a xenon flash charger IC from Monolithic Power Systems, designed for camera flash applications. It operates as a DC-DC regulator with flyback topology, delivering up to 2A output current and supporting a maximum output voltage of 60V. The device functions within an input supply range of 3V to 6V and withstands operating temperatures from -40°C to +85°C. Packaged in a 16-pin QFN (3x3mm) with exposed pad, it integrates charge management features for efficient energy storage in flash capacitors.

LED Driver IC Feature Summary

• Integrated xenon flash charge management controller
• Flyback DC-DC regulator topology for high-voltage generation
• Compact surface-mount QFN package design

LED Driver IC Applications

• Camera flash systems
• Mobile phone imaging modules
• Portable electronic devices requiring xenon illumination

LED Driver IC Procurement Notes

Verify the specific suffix 'P' against official MPS documentation to confirm packaging details such as reel or cut tape specifications. Confirm that the component meets RoHS requirements as indicated by the 'LF' designation. Ensure compatibility with existing flyback transformer designs and capacitor ratings suitable for the 60V output requirement.

LED Driver IC Selection Notes

Select this component when designing xenon-based flash circuits requiring a compact solution. The 2A current capability supports rapid charging cycles. Verify that the system input voltage remains within the 3V to 6V range. Consider thermal performance due to the QFN package's exposed pad requirement for heat dissipation during high-current operation.

LED Driver IC Part Context

This part belongs to the MP3351 series of display drivers and controllers. It is specifically categorized under charge management ICs. The manufacturer identifies it as a specialized solution for powering xenon flashes, distinct from standard LED backlight drivers found in other MPS product lines.

LED Driver IC Replacement Considerations

Check for direct pin-to-pin replacements within the MP3351 family. Verify if alternative packages like the LF-Z variant offer identical electrical characteristics. Consult official substitution guides for any updated versions with improved thermal or efficiency metrics.
