MP3399EF-LF-P

Overview

The MP3399EF-LF-P is a monolithic LED lighting driver IC designed for high-voltage white LED applications. It features a boost topology with 12 independent output channels, supporting up to 12-string configurations. The device operates within an input voltage range of 5 V to 28 V and utilizes a TSSOP-28 package. It functions at a switching frequency of 570 kHz and supports PWM dimming control. The component is rated for operation between -40°C and +125°C, with a maximum power dissipation of 3.9 W.

Feature Summary

Supports cascading or parallel driving of up to 12 white LED strings
Integrates internal current regulation for precise string matching
Includes protection mechanisms for open LED and overvoltage conditions

Applications

Large LCD backlighting systems
High-density white LED arrays
Industrial display illumination

Procurement Notes

Verify the specific suffix 'P' indicates tube packaging versus 'Z' for reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the selected variant matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component for designs requiring multi-string white LED control with high voltage inputs. Consider the TSSOP-28 footprint for layout constraints. Evaluate the 570 kHz switching frequency against EMI requirements. Compare against lower-channel alternatives if fewer than 12 strings are needed.

Part Context

This part belongs to the MP3399 series from Monolithic Power Systems, specialized for extending LED channel counts in display backlights. It complements other MPS drivers like the MP3389 by offering higher channel density. The series targets professional lighting solutions requiring uniform current distribution across multiple LED paths.
